We used our data as well as data from previous research to compile species lists for the memorial, assess inventory completeness, and make suggestions on future monitoring efforts. \r\n\r\nThere have been 940 species of plants and vertebrates recorded at Coronado NM (Table 1), of which 46 (5%) are non-native. The species richness of the memorial is one of the highest in the Sonoran Desert Network of park units, third only to park units that are two and one-half (Chiricahua National Monument), 19 (Saguaro National Park) and 70 (Organ Pipe Cactus National Monument) times larger in area. The high species diversities are due to the large elevational gradient, overlap of bigeographical regions, wide range of geology and soils, and diverse vegetation communities present at the memorial. \r\n\r\nChanges in species composition have occurred at the memorial over the last 20 years in all major taxonomic groups. These changes are likely due to increases in grassy plant species (both native and non-native) at the lower elevations of the memorial. We suspect that grassy plant cover has increased because of changes in grazing intensity, introduction of some non-native species, and a recent fire. All recent vertebrate inventories have yielded grassland obligate species not previously recorded at the memorial. \r\n\r\nBased on the review of past studies, we believe the inventory for most taxa, except bats, is nearly complete, though some rare or elusive species will likely be added with additional survey effort.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20071393","collaboration":"Prepared in cooperation with the University of Arizona School of Natural Resources","usgsCitation":"Powell, B., Swann, D.E., and Halvorson, W., 2007, Vascular Plant and Vertebrate Inventory of Coronado National Memorial (Version 1.0): U.S. Geological Survey Open-File Report 2007-1393, xiv, 114 p., https://doi.org/10.3133/ofr20071393.","productDescription":"xiv, 114 p.","onlineOnly":"Y","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":118675,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2007_1393.jpg"},{"id":12849,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1393/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.4,31.3 ], [ -110.4,31.4 ], [ -110.2,31.4 ], [ -110.2,31.3 ], [ -110.4,31.3 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7afde4b0b2908510dd80","contributors":{"editors":[{"text":"Schmidt, Cecilia A.","contributorId":47483,"corporation":false,"usgs":true,"family":"Schmidt","given":"Cecilia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":742840,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Powell, Brian F.","contributorId":25644,"corporation":false,"usgs":true,"family":"Powell","given":"Brian F.","affiliations":[],"preferred":false,"id":302905,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Swann, Don E.","contributorId":90002,"corporation":false,"usgs":true,"family":"Swann","given":"Don","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":302907,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halvorson, William L.","contributorId":97194,"corporation":false,"usgs":true,"family":"Halvorson","given":"William L.","affiliations":[],"preferred":false,"id":302908,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

From 2001 to 2003 we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at the district to document the presence of species within its boundaries. Park staff also carried out extensive infrared-triggered camera work for medium and large mammals from 2002-2005 and results from that effort are reported here. Our spatial sampling design for all taxa employed a combination of random and nonrandom survey sites. Survey effort was greatest for medium and large mammals and herpetofauna. Because we used repeatable study designs and standardized field methods, these inventories can serve as the first step in a biological monitoring program for the district. We also provide an overview of previous survey efforts in the district. We use data from our inventory and other surveys to compile species lists and to assess inventory completeness. \r\n\r\nThe survey effort for herpetofauna, birds, and medium and large mammals was the most comprehensive ever undertaken in the district. We recorded a total of 320 plant and vertebrate species, including 21 species not previously found in the district (Table 1). Based on a review of our inventory and past research at the district, there have been a total of 723 species of plants and vertebrates found there. We believe inventories for most taxonomic groups are nearly complete. \r\n\r\nBased on our surveys, we believe the native plant and vertebrate community compositions of the district are relatively intact, though some species loss has occurred and threats are increasing, particularly to herpetofauna and larger mammals. Of particular note is the relatively small number of non-native species and their low abundance in the district, which is in contrast to many nearby natural areas. Rapidly expanding development on the west, north, and east sides of the district is cause for concern that the park continue its commitment to environmental restoration, which is largely responsible for reducing the threats posed by non-native plants. With continued maintenance of natural processes and the ecological structure of the park's biodiversity, the park will become an increasingly important place to both the general public and the scientific community.\r\n\r\nThis report supersedes results reported in Powell et al.

From 2001 to 2003, we surveyed for vascular plants and vertebrates (amphibians, reptiles, birds, and mammals) at Tonto NM to record species presence. We focused most of our efforts along the Cave Springs riparian area, but surveyed other areas as well. We recorded 149 species in the riparian area, and 369 species overall in the monument, including 65 plant species and four bird species that were previously unrecorded for the monument. We recorded 78 plant species in the riparian area that previous studies had not indicated were present there. \r\n\r\nSeveral species of each taxonomic group were found only in the riparian area, suggesting that because of their concentration in this small area these populations are vulnerable to disturbance and may be of management concern. Four of the bird species that we recorded (Bell's vireo, yellow warbler, summer tanager, and Abert's towhee) have been identified as riparian 'obligate' species by other sources. Bird species that are obligated to riparian areas are targets of conservation concern due to widespread degradation of riparian areas in the desert southwest over the last century. \r\n\r\nThe flora and fauna of the riparian area would benefit from continued limited public access. The dependence of the riparian area on the spring and surface flow suggests monitoring of this resource per se would benefit management of the riparian area's flora and fauna as well. The monument would benefit from incorporating monitoring protocols developed by the Sonoran Desert Network Inventory and Monitoring program rather than initiating a separate program for the riparian area. Park managers can encourage the Inventory and Monitoring program to address the unique monitoring challenges presented by small spatial areas such as this riparian area, and can request specific monitoring recommendations. We suggest that repeat inventories for vertebrates, and census (rather than sampling) of perennial vegetation may be the most effective long-term monitoring strategies in the riparian area to verify species persistence through time in this unique and spatially limited environment.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr20071295","collaboration":"Prepared in cooperation with the University of Arizona School of Natural Resources","usgsCitation":"Albrecht, E.W., Powell, B., Halvorson, W., and Schmidt, C., 2007, Vascular Plant and Vertebrate Inventory of Tonto National Monument (Version 1.0): U.S. Geological Survey Open-File Report 2007-1295, xii, 57 p., https://doi.org/10.3133/ofr20071295.","productDescription":"xii, 57 p.","onlineOnly":"Y","temporalStart":"2001-01-01","temporalEnd":"2003-12-31","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":125449,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_2007_1295.jpg"},{"id":12805,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1295/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.8,33.3 ], [ -110.8,33.4 ], [ -110.7,33.4 ], [ -110.7,33.3 ], [ -110.8,33.3 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48d4e4b07f02db548efa","contributors":{"authors":[{"text":"Albrecht, Eric W.","contributorId":8568,"corporation":false,"usgs":true,"family":"Albrecht","given":"Eric","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":302782,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Powell, Brian F.","contributorId":25644,"corporation":false,"usgs":true,"family":"Powell","given":"Brian F.","affiliations":[],"preferred":false,"id":302783,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Halvorson, William L.","contributorId":97194,"corporation":false,"usgs":true,"family":"Halvorson","given":"William L.","affiliations":[],"preferred":false,"id":302785,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schmidt, Cecilia A.","contributorId":25645,"corporation":false,"usgs":true,"family":"Schmidt","given":"Cecilia A.","affiliations":[],"preferred":false,"id":302784,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Two units of the Gulf Islands National Seashore (GUIS), located on Santa Rosa Island, a barrier island off the Panhandle coast of Florida, were highly impacted during the hurricanes of 2004 (Ivan) and 2005 (Cindy, Dennis, Katrina and Rita).  In addition to the loss of or damage to natural and cultural resources within the park, damage to park infrastructure, including park access roads and utilities, occurred in areas experiencing rapid shoreline retreat.  The main park road was located as close as 50 m to the pre-storm (2001) shoreline and was still under repair from damage incurred during Hurricane Ivan when the 2005 hurricanes struck.  A new General Management Plan is under development for the Gulf Islands National Seashore.  This plan, like the existing General Management Plan, strives to incorporate natural barrier island processes, and will guide future efforts to provide access to units of Gulf Islands National Seashore on Santa Rosa Island.  To assess changes in island geomorphology and provide data for park management, the National Park Service and the U.S. Geological Survey are currently analyzing shoreline change to better understand long-term (100+ years) shoreline change trends as well as short-term shoreline impact and recovery to severe storm events.  Results show that over an ~140-year period from the late 1800s to May 2004, the average shoreline erosion rates in the Fort Pickens and Santa Rosa units of GUIS were -0.7m/yr and -0.1 m/yr, respectively.  Areas of historic erosion, reaching a maximum rate of -1.3 m/yr, correspond to areas that experienced overwash and road damage during the 2004 hurricane season.  The shoreline eroded as much as ~60 m during Hurricane Ivan, and as much as ~88 m over the course of the 2005 storm season.  The shoreline erosion rates in the areas where the park road was heavily damaged were as high as -70.2 m/yr over the 2004-2005 time period.  Additional post-storm monitoring of these sections of the island, to assess whether erosion rates stabilize, will help to parks to determine the best long-term management strategy for the park infrastructure.","language":"English","publisher":"U.S. Geological Survey.","collaboration":"  PDF on file: 6885_Hapke.pdf","usgsCitation":"Hapke, C., and Christiano, M., 2007, Long-term and storm-related shoreline change trends in the Florida Gulf Islands National Seashore: Open-File Report 2007-1392., 18.","productDescription":"18","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202971,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6de4b07f02db63edb9","contributors":{"authors":[{"text":"Hapke, C.J.","contributorId":108233,"corporation":false,"usgs":true,"family":"Hapke","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":327545,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Christiano, M.","contributorId":6975,"corporation":false,"usgs":true,"family":"Christiano","given":"M.","affiliations":[],"preferred":false,"id":327544,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

I have implemented this method in the statistical computing language R (R Development Core Team, 2007), so that it is freely and easily available to researchers and practitioners that may find it useful. I originally applied an early version of these routines to seismic cone penetration test data (SCPT) to analyze the horizontal variability of shear-wave velocity within the sediments in the San Francisco Bay area (Thompson et al., 2006). A more recent version of these codes was used to analyze the influence of interface-selection and model assumptions on velocity/slowness estimates and the resulting differences in site amplification (Boore and Thompson, 2007). The R environment has many benefits for scientific and statistical computation; I have chosen R to disseminate these routines because it is versatile enough to program specialized routines, is highly interactive which aids in the analysis of data, and is freely and conveniently available to install on a wide variety of computer platforms.\r\n\r\nThese scripts are useful for the interpretation of layered velocity models from surface-source downhole seismic data such as deep boreholes and SCPT data. The inputs are the travel-time data and the offset of the source at the surface. The travel-time arrivals for the P- and S-waves must already be picked from the original data. An option in the inversion is to include estimates of the standard deviation of the travel-time picks for a weighted inversion of the velocity profile. The standard deviation of each travel-time pick is defined relative to the standard deviation of the best pick in a profile and is based on the accuracy with which the travel-time measurement could be determined from the seismogram.\r\n\r\nThe analysis of the travel-time data consists of two parts: the identification of layer-interfaces, and the inversion for the velocity of each layer. The analyst usually picks layer-interfaces by visual inspection of the travel-time data. I have also developed an algorithm that automatically finds boundaries which can save a significant amount of the time when analyzing a large number of sites. The results of the automatic routines should be reviewed to check that they are reasonable. The interactivity of these scripts allows the user to add and to remove layers quickly, thus allowing rapid feedback on how the residuals are affected by each additional parameter in the inversion. In addition, the script allows many models to be compared at the same time.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20071124","usgsCitation":"Thompson, E., 2007, Surface-source downhole seismic analysis in R (Version 1.0): U.S. Geological Survey Open-File Report 2007-1124, Report: iii, 14 p.; Install Packages, https://doi.org/10.3133/ofr20071124.","productDescription":"Report: iii, 14 p.; Install Packages","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":195789,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":12288,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1124/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae6e4b07f02db68b7b8","contributors":{"authors":[{"text":"Thompson, Eric M.","contributorId":79193,"corporation":false,"usgs":false,"family":"Thompson","given":"Eric M.","affiliations":[{"id":6608,"text":"San Diego State University","active":true,"usgs":false}],"preferred":false,"id":301455,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

At the Beatson, Ellamar, and Threeman mine sites (fig. 1), rocks containing Fe, Cu, Zn, and Pb sulfide minerals are exposed to chemical weathering in abandoned mine workings and remnant waste piles that extend into the littoral zone. Field investigations in 2003 and 2005 as well as analytical data for rock, sediment, precipitate, water, and biological samples reveal that the oxidation of sulfides at these sites is resulting in the generation of acid mine drainage and the transport of metals into the marine environment (Koski and others, 2008; Stillings and others, 2008). \r\n\r\nAt the Ellamar and Threeman sites, plumes of acidic and metal-enriched water are flowing through beach gravels into the shallow offshore environment. Interstitial water samples collected from beach sediment at Ellamar have low pH levels (to ~3) and high concentrations of metals including iron, copper, zinc, cobalt, lead, and mercury. The abundant precipitation of the iron sulfate mineral jarosite in the Ellamar gravels also signifies a low-pH environment. At the Beatson mine site (the largest copper mine in the region) seeps containing iron-rich microbial precipitates drain into the intertidal zone below mine dumps (Foster and others, 2008). A stream flowing down to the shoreline from underground mine workings at Beatson has near-neutral pH, but elevated levels of zinc, copper, and lead (Stillings and others, 2008). Offshore sediment samples at Beatson are enriched in these metals. Preliminary chemical data for tissue from marine mussels collected near the Ellamar, Threeman, and Beatson sites reveal elevated levels of copper, zinc, and lead compared to tissue in mussels from other locations in Prince William Sound (Koski and others, 2008). \r\n\r\nThree papers presenting results of this ongoing investigation of sulfide oxidation in Prince William Sound are in press. Koski and others (2008) provide an overview of rock alteration, surface water chemistry, and the distribution of metals at the Ellamar, Threeman, and Beatson mine sites. Based on a 60-day, stream-discharge experiment at Beatson in 2005, Stillings and others (2008) analyze changes in water chemistry during storm events and the flux of metals to the shoreline. Foster and others (2008) investigate the biomass and diversity of microbial communities present in surface waters (streams, seeps, pore waters) using fatty acid methyl ester (FAMES) data and principal component analysis.

This study documents historical shoreline changes at Rincon for the period 1936-2006 and constitutes a significant expansion and revision of previous work. The study area extends approximately 8 km from Punta Higuero to Punta Cadena. Fourteen historical shoreline positions were compiled from existing data, new orthophotography, and Global Positioning System (GPS) field surveys.\r\n\r\nThe study area can be divided into four distinct reaches on the basis of observed erosion rates, consistent with previous work. The coast of Reach A, from Punta Higuero to the north end of the Balneario de Rincon, is fairly stable and has a long-term (70 years) average erosion rate of -0.2 ? 0.1 m/yr. The coast of Reach B, from the Balneario de Rincon to 500 m south of the mouth of Quebrada los Ramos, has an average long-term erosion rate of -1.1 ? 0.3 m/yr. The coast of Reach C, from 500 m south of the mouth of Quebrada los Ramos to Corcega, has an average long-term erosion rate of -0.4 ? 0.2 m/yr. The coast of Reach D, from Corcega to Punta Cadena, has an average long-term change rate of -0.2 ? 0.2 m/yr.\r\n\r\nPrevious work (Thieler and others, 1995) identified an apparent increase in erosion rate in Reach B that probably began between 1977 and 1987. New data and statistical analysis suggest that long-term and short-term rates of shoreline change are statistically similar. Nevertheless, the coast in Reach B is eroding at a rapid and statistically significant rate that is 2 to 10 times greater than in the other three reaches. Comparison of the 1994 and 2006 GPS shoreline positions indicates the following erosion rates occurred over the past 12 years: Reach A, -0.3 ? 0.4 m/yr; Reach B, -1.0 ? 0.4 m/yr; Reach C, -0.7 ? 0.4 m/yr; and Reach D, -0.3 ? 0.4 m/yr.\r\n\r\nThieler and others (1995) speculated that the increased erosion rate in Reach B could be attributed to the effects of marina construction in 1983 on the local sediment budget. New data and analysis suggest, however, that other factors may be equally or perhaps more important. For example, high-resolution lidar bathymetric data collected in 2001 show a complex nearshore bathymetry that may substantially affect wave refraction, diffraction, and reflection in Reach B where erosion rates are the highest. In addition, several historical photographs dating from 1951 to 2006 show a wide array of complex wave patterns that suggest the bathymetric influence on nearshore processes to be a long-term, rather than recent, phenomenon. In addition, removal of sand from the beach system may be contributing further to the elevated erosion rates in Reach B.\r\n\r\nDevelopment of potential options for addressing coastal erosion in Rincon was beyond the scope of this study, but the data and interpretations presented here provide a sound scientific foundation for further work to identify the causes of the increased erosion and to develop strategies to mitigate its effect.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20071017","usgsCitation":"Thieler, E.R., Rodriguez, R.W., and Himmelstoss, E., 2007, Historical Shoreline Changes at Rincon, Puerto Rico, 1936-2006: U.S. Geological Survey Open-File Report 2007-1017, v, 32 p., https://doi.org/10.3133/ofr20071017.","productDescription":"v, 32 p.","temporalStart":"1936-01-01","temporalEnd":"2006-12-31","costCenters":[{"id":680,"text":"Woods Hole Science Center","active":false,"usgs":true}],"links":[{"id":195508,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":11353,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://woodshole.er.usgs.gov/pubs/of2007-1017/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -67.28333333333333,18.284444444444446 ], [ -67.28333333333333,18.366666666666667 ], [ -67.2175,18.366666666666667 ], [ -67.2175,18.284444444444446 ], [ -67.28333333333333,18.284444444444446 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6ade89","contributors":{"authors":[{"text":"Thieler, E.

Scott and Kepler (1985) provided a comprehensive review of the status of native Hawaiian birds based on the extensive Hawaii Forest Bird Survey (HFBS) of the main islands (Scott et al. 1986). At that time, they documented declining populations and decreasing ranges for most species, and the extinction of several species over the previous 50 years. Many native bird species continue to decline throughout Hawai`i (Camp et al. In review, Gorresen et al. In prep.).\r\nThe focus of this study is the mid-to-high elevation rainforest on the southeast windward slopes of Mauna Loa Volcano (Figure 1). Known as Ka`u, the region encompasses forest lands protected by Kamehameha Schools, The Nature Conservancy, Hawai`i Volcanoes National Park (HVNP), and the State of Hawai'i's Ka`u Forest Reserve, Kapapala Forest Reserve and Kapapala Cooperative Game Management Area,. Together these lands support one of three main concentrations of native forest birds on the Hawai`i Island (the other two being centered on the Hakalau Forest National Wildlife Refuge and Kulani-Keauhou area in the north and central windward part of the island, respectively.)\r\nBecause this region harbors important populations of native and endangered forest birds in some of the best remaining forest habitat on the island, it has been a focus of forest bird surveys since the 1970s. The Ka`u region was first quantitatively surveyed in 1976 by the Hawaii Forest Bird Survey (Scott et al. 1986). Surveys were conducted by State of Hawai`i Division of Forestry and Wildlife in 1993 and 2002 and by the U.S. National Park Service and the U.S. Geological Survey in 2004 and 2005.\r\nIn this report, we present analyses of the density, distribution and trends of native and introduced forest bird within the Ka`u region of Hawai`i Island. The analyses cover only those species with sufficient detections to model detection probability and calculate density. These include three endangered native passerines: `Akiapola`au (Hemignathus munroi), Hawai`i Creeper (Oreomystis mana), and Hawai`i `Akepa (Loxops coccineus); five more common native passerines: the Hawai`i `Elepaio (Chasiempis sandwichensis), `Oma`o (Myadestes obscurus), Hawai`i `Amakihi (Hemignathus virens), `I`iwi (Vestiaria coccinea) and `Apapane (Himatione sanguinea); and three non-native species: Red-billed Leiothrix (Leiothrix lutea), Japanese White-eye (Zosterops japonicus), and Northern Cardinal (Cardinalis cardinalis).","language":"ENGLISH","publisher":"Geological Survey (U.

More than a dozen facilities are, or soon will be, online to benefit native fish. When this study began in 2005 no self-supporting communities of either bonytail or razorback sucker existed. Razorback suckers were removed from Rock Tank in 1997 and the communities at High Levee Pond had been compromised by largemouth bass in 2004. This project reversed that trend with the establishment of the Davis Cove native fish community in 2005. Bonytail and razorback sucker successfully produced young in Davis Cove in 2006. Bonytail successfully produced young in Parker Dam Pond in 2007, representing the first successful sanctuary established solely for bonytail. This past year, Three Fingers Lake received 135 large razorback suckers, and Federal and State agencies have agreed to develop a cooperative management approach dedicating a portion of that lake toward grow-out and (or) the establishment of another sanctuary. Two ponds at River's Edge Golf Course in Needles, California, were renovated in June and soon will be stocked with bonytail. Similar activities are taking place at Mohave Community College, Cerbat Cliffs Golf Course, Cibola High Levee Pond, Office Cove, Emerald Canyon Golf Course, and Bulkhead Cove. Recruitment can be expected as fish become sexually mature at these facilities. Flood-plain facilities have the potential to support 6,000 adult razorback suckers and nearly 20,000 bonytail if native fish management is aggressively pursued. This sanctuary project has assisted agencies in developing 15 native fish communities by identifying specific resource objectives for those sites, listing and prioritizing research opportunities and needs, and strategizing on management approaches through the use of resource-management plans. Such documents have been developed for Davis Cove, Cibola High Levee Pond, Parker Dam Pond, and Three Fingers Lake. We anticipate similar documents will be developed in the near future for River's Edge Golf Course Ponds, Office Cove, Emerald Canyon Golf Course Ponds, Bulkhead Cove, Mohave Community College, and Cerbat Cliffs Golf Course ponds as these facilities come on line or are developed in the future. The following report discusses the process that went into the development of these facilities. Sites were visited, assessed as to their suitability based on the control of nonnative predators, habitat suitability, conversion cost, logistics, geographical location, and willingness of landowners. They were then prioritized according to their suitability, cost, timely conversion, and willingness of landowners. Existing native fish facilities were included in this evaluation for their value in helping to determine physical and biological parameter ranges. This report describes the approaches that led to success, those leading to failure, and some of the biological, institutional, and management issues of implementing native fish sanctuary development.</p>","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20081126","collaboration":"Prepared in cooperation with the Bureau of Reclamation, Interagency Acquisition No. 05AA300014, Lower Colorado Regional Office, Boulder City, Nevada","usgsCitation":"Mueller, G.A., 2007, Native Fish Sanctuary Project - Sanctuary Development Phase, 2007 Annual Report (Version 1.0): U.S. Geological Survey Open-File Report 2008-1126, viii, 59 p., https://doi.org/10.3133/ofr20081126.","productDescription":"viii, 59 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":195227,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":11309,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2008/1126/","linkFileType":{"id":5,"text":"html"}},{"id":320127,"rank":101,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2008/1126/pdf/OF08-1126.pdf","linkFileType":{"id":1,"text":"pdf"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1ae4b07f02db606343","contributors":{"authors":[{"text":"Mueller, Gordon A.","contributorId":86420,"corporation":false,"usgs":true,"family":"Mueller","given":"Gordon","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":295011,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The principal causes of the observed declines are difficult to confirm, however, because only a few of the many factors that affect mussel-species populations have been identified (Strayer and Ralley, 1993; Strayer, 1999; Baldigo and others, 2003; Strayer and others, 2006).\r\n\r\nThe Neversink River, which drains the Catskill Mountains in southeastern New York (fig. 1), contains seven species of mussels (Strayer and Ralley, 1991; Strayer and Jirka, 1997). Populations of the endangered dwarf wedgemussel (Alasmidonta heterodon) and the threatened swollen wedgemussel (Alasmidonta varicosa) coexist with other unionid mussels in the Neversink River (Strayer and Ralley, 1991, 1993; Baldigo and others, 2003). Dwarf wedgemussel populations had previously been found only downstream from the site of an abandoned dam in the lower part of the river at Cuddebackville (fig. 1), and swollen wedgemussels were only found in the lower and middle reaches of the river. The limited distribution of these two species suggests that they may be susceptible to local extinctions.\r\n\r\nThe distribution of mussel populations can be limited by impoundments. Mussel larvae develop in species-specific host fish; thus, impoundments that restrict passage of these host fish also restrict the extent of mussels. The Neversink River is impounded by the Neversink Reservoir [241 square kilometers (km2)], a major source of drinking water for the City of New York, and was also impounded 50 km downstream by the Cuddebackville Dam until 2004, when the latter was removed by The Nature Conservancy (TNC) and the U.S. Army Corps of Engineers to improve fish passage. The removal of this dam has provided previously unavailable habitat for diadromous and other fish species that act as hosts for rare mussel species. In addition, releases from the Neversink Reservoir that mimic the river?s original flow patterns have recently been proposed by TNC and could benefit the established mussel populations and aquatic communities. The ability to protect mussel populations and the potential to increase mussel richness in the Neversink River is unknown, however, because the environmental factors that affect the seven mussel species are poorly defined, and the distribution of mussel beds is patchy and thus difficult to quantify.\r\n\r\nIn 1997, the U.S. Geological Survey, in cooperation with TNC, began a 6-year study along the Neversink River and its tributaries to (1) document the current distribution of each mussel species, (2) assess environmental factors in relation to mussel-species richness and distribution, and (3) identify the factors that most strongly affect mussel populations and develop an equation that relates environmental factors to mussel-species richness. This report (a) summarizes the methods used to quantify or qualify environmental factors and mussel-species distribution and abundance, (b) presents a list of environmental factors that were correlated with mussel-species richness, and (c) offers an empirical model to predict richness of mussel species in benthic communities throughout the basin.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20071283","collaboration":"Prepared in cooperation with The Nature Conservancy and Sullivan County Division of Planning and Environmental Management","usgsCitation":"Baldigo, B.P., Ernst, A., Schuler, G.E., and Apse, C.D., 2007, Relations of Environmental Factors with Mussel-Species Richness in the Neversink River, New York: U.S. Geological Survey Open-File Report 2007-1283, 8 p., https://doi.org/10.3133/ofr20071283.","productDescription":"8 p.","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":190570,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10910,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1283/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b31e4b07f02db6b411a","contributors":{"authors":[{"text":"Baldigo, Barry P. 0000-0002-9862-9119 bbaldigo@usgs.gov","orcid":"https://orcid.org/0000-0002-9862-9119","contributorId":1234,"corporation":false,"usgs":true,"family":"Baldigo","given":"Barry","email":"bbaldigo@usgs.gov","middleInitial":"P.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":294213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ernst, Anne G.","contributorId":37825,"corporation":false,"usgs":true,"family":"Ernst","given":"Anne G.","affiliations":[],"preferred":false,"id":294215,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schuler, George E.","contributorId":37005,"corporation":false,"usgs":true,"family":"Schuler","given":"George","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":294214,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Apse, Colin D.","contributorId":54680,"corporation":false,"usgs":true,"family":"Apse","given":"Colin","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":294216,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Water level within the pool was reduced by 0.3 m (1.0 ft) beginning July 5, 1995, exposing about 1,591 ha (3,931 acres) of sediment; the reduced water level was maintained until October 25 of that year. A total of 15 transects was established along the pool margin before the drawdown, extending perpendicular from the pool edge to 19.5 m (64.0 ft) in elevation. Plant species composition and cover were recorded at six to seven quadrats on each transect; 14 of the transects were also monitored three times during the drawdown and in June 1996. Soil near five of the original transects was disturbed two weeks into the drawdown by scraping the soil surface with a bulldozer. Soil cores were collected to characterize soil organic matter, texture class, carbon and nitrogen content, and plant nutrient concentrations; soil samples were also collected to identify species present in the seed bank prior to and during the drawdown.\r\n\r\nPlant species, several of which were high quality food sources for waterfowl, colonized the drawdown zone within four weeks. Vegetation response, measured by species richness, total cover, and cover of Cyperus species, was often greater at low compared to high elevations in the drawdown zone; this effect was probably intensified by low rainfall during the summer of 1995. Vegetation response on the disturbed transects was reduced compared to that on the undisturbed transects. This effect was attributed to two factors: (1) removal of the existing seed bank by the disturbance technique applied and (2) reduced incorporation of seeds recruited during the drawdown because of unusually low summer rainfall. Seed bank studies demonstrated that several species persisted despite nearly 10 years of continual flooding, and that seed bank species richness increased during the drawdown. Analyses indicated that predominantly clay soils containing relatively low organic matter were present along the pool margin. Levels of the plant nutrients measured were consistent with normal values reported for soils. Although conclusions from this study are limited by its one-year time frame, it is unlikely that permanent change to plant community function in the drawdown zone resulted from the lowered water levels during the summer of 1995. While species composition in the summer following the drawdown differed from that prior to the drawdown, the plant community remained dominated by annual floating-leaved or submersed species. It is probable that any future decrease in summer water levels in the pool will result in increased growth of desirable waterfowl food plants, such as Cyperus erythrorhizos (red-root flat sedge) and Leptochloa fascicularis var. fascicularis (bearded sprangletop), in the drawdown zone.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20071379","usgsCitation":"Howard, R.J., and Wells, C.J., 2007, Vegetation Response to the 1995 Drawdown of the Navigation Pool at Felsenthal National Wildlife Refuge, Crossett, Arkansas (Version 1.0): U.S. Geological Survey Open-File Report 2007-1379, vi, 52 p., https://doi.org/10.3133/ofr20071379.","productDescription":"vi, 52 p.","onlineOnly":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":110767,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_83406.htm","linkFileType":{"id":5,"text":"html"},"description":"83406"},{"id":194913,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10898,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1379/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a14e4b07f02db602733","contributors":{"authors":[{"text":"Howard, Rebecca J. 0000-0001-7264-4364 howardr@usgs.gov","orcid":"https://orcid.org/0000-0001-7264-4364","contributorId":2429,"corporation":false,"usgs":true,"family":"Howard","given":"Rebecca","email":"howardr@usgs.gov","middleInitial":"J.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true}],"preferred":true,"id":294179,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wells, Christopher J. wellsc@usgs.gov","contributorId":5607,"corporation":false,"usgs":true,"family":"Wells","given":"Christopher","email":"wellsc@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":294180,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

One approach to understanding the dynamics of coastal systems is to monitor changes in barrier-island sub-environments through time. This involves examining morphological and topographic change at time scales ranging from millennia to years and space scales ranging from tens of kilometers to meters. Of particular interest are the processes that produce those changes and determining whether or not those processes are likely to persist into the future. In these analyses of hazards and change, both natural and anthropogenic influences are considered. Quantifying past magnitudes and rates of coastal change and knowing the principal factors that govern those changes are critical to predicting what changes are likely to occur under different scenarios, such as short-term impacts of extreme storms or long-term impacts of sea-level rise. Assateague Island MD/VA was selected for detailed mapping of barrier island morphology and topography because the island offers a diversity of depositional sub-environments that are representative of other barrier islands along the middle Atlantic coast. The geomorphology and sub-environment map emphasizes the origins of the surficial features and it also serves as a basis for documenting which sub-environments are relatively stable, such as the barrier island core, and those that are highly dynamic, such as the beach and active overwash zones.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20071388","usgsCitation":"Morton, R., Bracone, J.E., and Cooke, B., 2007, Geomorphology and depositional sub-environments of Assateague Island MD/VA: U.S. Geological Survey Open-File Report 2007-1388, HTML Document, https://doi.org/10.3133/ofr20071388.","productDescription":"HTML Document","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":293642,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2007/1388/start.html","linkFileType":{"id":5,"text":"html"}},{"id":195707,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20071388.PNG"},{"id":10896,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1388/","linkFileType":{"id":5,"text":"html"}},{"id":408106,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_83417.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryland, Virginia","otherGeospatial":"Assateague Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.08468627929688,\n              38.320649556775365\n            ],\n            [\n              -75.10116577148438,\n              38.326036454199986\n            ],\n            [\n              -75.17738342285156,\n              38.20365531807149\n            ],\n            [\n              -75.24124145507812,\n              38.08052761936274\n            ],\n            [\n              -75.27626037597656,\n              38.0470096014159\n            ],\n            [\n              -75.31196594238281,\n              38.00049145082287\n            ],\n            [\n              -75.31196594238281,\n              37.97289115798956\n            ],\n            [\n              -75.32638549804688,\n              37.95123660520783\n            ],\n            [\n              -75.32157897949219,\n              37.94311450175187\n            ],\n            [\n              -75.34629821777344,\n              37.92090950501414\n            ],\n            [\n              -75.37925720214844,\n              37.91007536562636\n            ],\n            [\n              -75.40191650390624,\n              37.86997517701081\n            ],\n            [\n              -75.39779663085938,\n              37.84069909534387\n            ],\n            [\n              -75.35316467285156,\n              37.85804928797244\n            ],\n            [\n              -75.25978088378906,\n              37.99562156537659\n            ],\n            [\n              -75.18562316894531,\n              38.09457899232251\n            ],\n            [\n              -75.14785766601562,\n              38.194481913956864\n            ],\n            [\n              -75.08468627929688,\n              38.320649556775365\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c4e1","contributors":{"authors":[{"text":"Morton, Robert A.","contributorId":88333,"corporation":false,"usgs":true,"family":"Morton","given":"Robert A.","affiliations":[],"preferred":false,"id":294176,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bracone, Jeremy E.","contributorId":16944,"corporation":false,"usgs":true,"family":"Bracone","given":"Jeremy","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":294174,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cooke, Brian","contributorId":22456,"corporation":false,"usgs":true,"family":"Cooke","given":"Brian","email":"","affiliations":[],"preferred":false,"id":294175,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Even at Fire Island National Seashore, a barrier-island coastal park in New York where extratropical storms (northeasters) dominate storm activity, the beaches are vulnerable to the powerful, sand-moving forces of hurricanes. The vulnerability of park beaches to inundation, and associated extreme coastal change, during a direct hurricane landfall can be assessed by comparing the elevations of storm-induced mean-water levels (storm surge) to the elevations of the crest of the sand dune that defines the beach system. Maps detailing the inundation potential for Category 1-4 hurricanes can be used by park managers to determine the relative vulnerability of various barrier-island parks and to assess which areas of a particular park are more susceptible to inundation and extreme coastal changes.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20071389","usgsCitation":"Stockdon, H.F., and Thompson, D.M., 2007, Vulnerability of National Park Service beaches to inundation during a direct hurricane landfall: Fire Island National Seashore: U.S. Geological Survey Open-File Report 2007-1389, 8 p., https://doi.org/10.3133/ofr20071389.","productDescription":"8 p.","numberOfPages":"8","onlineOnly":"Y","costCenters":[{"id":277,"text":"Florida Integrated Science Center - St. Petersburg","active":false,"usgs":true}],"links":[{"id":195191,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20071389.PNG"},{"id":10886,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1389/","linkFileType":{"id":5,"text":"html"}},{"id":294992,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2007/1389/ofr2007-1389.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":415292,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_83415.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"New York","otherGeospatial":"Fire Island National Seashore","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -73.4,40.55 ], [ -73.4,40.8 ], [ -72.7,40.8 ], [ -72.7,40.55 ], [ -73.4,40.55 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49a2e4b07f02db5bf1e2","contributors":{"authors":[{"text":"Stockdon, Hilary F. 0000-0003-0791-4676 hstockdon@usgs.gov","orcid":"https://orcid.org/0000-0003-0791-4676","contributorId":2153,"corporation":false,"usgs":true,"family":"Stockdon","given":"Hilary","email":"hstockdon@usgs.gov","middleInitial":"F.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true},{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"preferred":true,"id":294151,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thompson, David M. 0000-0002-7103-5740 dthompson@usgs.gov","orcid":"https://orcid.org/0000-0002-7103-5740","contributorId":3502,"corporation":false,"usgs":true,"family":"Thompson","given":"David","email":"dthompson@usgs.gov","middleInitial":"M.","affiliations":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":294152,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The preservation of the Nisqually delta ecosystem coupled with extensive restoration of approximately 1,000 acres of diked estuarine habitat is identified as the highest priority action for the recovery of naturally spawning Nisqually River Fall Chinook salmon (Oncorhynchus tshawytscha) in the Nisqually Chinook Recovery Plan.\r\n\r\nIn order to evaluate the response of Chinook salmon to restoration, a pre-restoration baseline of life history diversity and estuary utilization must be established. Otolith analysis has been proposed as a means to measure Chinook salmon life history diversity, growth, and residence in the Nisqually estuary. Over time, the information from the otolith analyses will be used to: (1) determine if estuary restoration actions cause changes to the population structure (i.e. frequency of the different life history trajectories) for Nisqually River Chinook, (2) compare pre and post restoration residence times and growth rates, and (3) suggest whether estuary restoration yields substantial benefits for Chinook salmon.\r\n\r\nOtoliths are calcium carbonate structures in the inner ear that grow in proportion to the overall growth of the fish. Daily growth increments can be measured so date and fish size at various habitat transitions can be back-calculated. Careful analysis of otolith microstructure can be used to determine the number of days that a fish resided in the estuary as a juvenile (increment counts), size at entrance to the estuary, size at egress, and the amount that the fish grew while in the estuary. Juvenile Chinook salmon can exhibit a variety of life history trajectories ? some enter the sea (or Puget Sound) as fry, some rear in the estuary before entering the sea, and some rear in the river and then move rapidly through the estuary into the sea as smolts.\r\n\r\nThe purpose of this study is to evaluate and use analysis of otolith microstructure as a tool for characterizing the importance of the estuary to Chinook salmon in the Nisqually River before and after restoration efforts at the Nisqually National Wildlife Refuge (NNWR). This tool is used to quantify changes in habitat use and help assess restoration benefits to the federally threatened Nisqually River Chinook salmon population.\r\n\r\nAnalysis of otolith microstructure typically is superior to the alternative of traditional mark-recapture methods. The latter are extremely expensive or inadequate in estuary habitats, typically are biased and substantially underestimate use, and do not directly reveal the importance or contribution to adult recruitment (i.e., they do not account for differential survival afterward in Puget Sound or the ocean). Analysis of otolith microstructure for these purposes, while new, is proving highly successful in a similar study that USGS and partners are conducting in the Skagit River estuary system located in northern Puget Sound. This work has been based on research by Neilson et al. (1985). We expect to use the Skagit River data as a reference for the before/after restoration comparison in the Nisqually River.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20081021","usgsCitation":"Lind-Null, A., Larsen, K., and Reisenbichler, R., 2007, Pre-Restoration Habitat Use by Chinook Salmon in the Nisqually Estuary Using Otolith Analysis: U.S. Geological Survey Open-File Report 2008-1021, iii, 13 p., https://doi.org/10.3133/ofr20081021.","productDescription":"iii, 13 p.","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":190958,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10833,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2008/1021/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad1e4b07f02db681200","contributors":{"authors":[{"text":"Lind-Null, Angela","contributorId":92356,"corporation":false,"usgs":true,"family":"Lind-Null","given":"Angela","email":"","affiliations":[],"preferred":false,"id":294002,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Larsen, Kimberly","contributorId":95569,"corporation":false,"usgs":true,"family":"Larsen","given":"Kimberly","affiliations":[],"preferred":false,"id":294003,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Reisenbichler, Reginald","contributorId":29903,"corporation":false,"usgs":true,"family":"Reisenbichler","given":"Reginald","affiliations":[],"preferred":false,"id":294001,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Goleta map overlaps an earlier preliminary geologic map of the central part of the coastal plain (Minor and others, 2002) that provided coverage within the coastal, central parts of the Goleta and contiguous Santa Barbara quadrangles. In addition to new mapping in the northern part of the Goleta quadrangle, geologic mapping in other parts of the map area has been revised from the preliminary map compilation based on new structural interpretations supplemented by new biostratigraphic data. All surficial and bedrock map units are described in detail in the accompanying map pamphlet. Abundant biostratigraphic and biochronologic data based on microfossil identifications are presented in expanded unit descriptions of the marine Neogene Monterey and Sisquoc Formations. Site-specific fault-kinematic observations (including slip-sense determinations) are embedded in the digital map database.\r\n\r\nThe Goleta quadrangle is located in the western Transverse Ranges physiographic province along an east-west-trending segment of the southern California coastline about 100 km (62 mi) northwest of Los Angeles. The Santa Barbara coastal plain surface, which spans the central part of the quadrangle, includes several mesas and hills that are geomorphic expressions of underlying, potentially active folds and partly buried oblique and reverse faults of the Santa Barbara fold and fault belt (SBFFB). Strong earthquakes have occurred offshore within 10 km of the Santa Barbara coastal plain in 1925 (6.3 magnitude), 1941 (5.5 magnitude) and 1978 (5.1 magnitude). These and numerous smaller seismic events located beneath and offshore of the coastal plain, likely occurred on reverse-oblique-slip faults that are similar to, or continuous with, Quaternary reverse faults crossing the coastal plain. Thus, faults of the SBFFB pose a significant earthquake hazard to the approximately 200,000 people living within the major coastal population centers of Santa Barbara and Goleta. In addition, numerous Quaternary landslide deposits along the steep southern flank of the Santa Ynez Mountains indicate the potential for continued slope failures and mass movements in developed areas. Folded, faulted, and fractured sedimentary rocks in the subsurface of the coastal plain and adjacent Santa Barbara Channel are sources and form reservoirs for economic deposits of oil and gas, some of which are currently being extracted offshore. Shallow, localized sedimentary aquifers underlying the coastal plain provide limited amounts of water for the urban areas, but the quality of some of this groundwater is compromised by coastal salt-water contamination. The present map compilation provides a set of uniform geologic digital coverages that can be used for analysis and interpretation of these and other geologic hazards and resources in the Goleta region.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr20071403","usgsCitation":"Minor, S.A., Kellogg, K., Stanley, R.G., and Brandt, T.R., 2007, Geologic Map of the Goleta Quadrangle, Santa Barbara County, California (Version 1.0): U.S. Geological Survey Open-File Report 2007-1403, Pamphlet: 41 p.; Map: 60 x 36 inches; Downloads Directory; ReadMe; Metadata, https://doi.org/10.3133/ofr20071403.","productDescription":"Pamphlet: 41 p.; Map: 60 x 36 inches; Downloads Directory; ReadMe; Metadata","additionalOnlineFiles":"Y","costCenters":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":110763,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_83282.htm","linkFileType":{"id":5,"text":"html"},"description":"83282"},{"id":190604,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10791,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2007/1403/","linkFileType":{"id":5,"text":"html"}}],"scale":"24000","projection":"Polyconic","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -119.86749999999999,34.3675 ], [ -119.86749999999999,34.5 ], [ -119.75,34.5 ], [ -119.75,34.3675 ], [ -119.86749999999999,34.3675 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a8514","contributors":{"authors":[{"text":"Minor, Scott A. 0000-0002-6976-9235 sminor@usgs.gov","orcid":"https://orcid.org/0000-0002-6976-9235","contributorId":765,"corporation":false,"usgs":true,"family":"Minor","given":"Scott","email":"sminor@usgs.gov","middleInitial":"A.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":293893,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kellogg, Karl S.","contributorId":89896,"corporation":false,"usgs":true,"family":"Kellogg","given":"Karl S.","affiliations":[],"preferred":false,"id":293896,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stanley, Richard G. 0000-0001-6192-8783 rstanley@usgs.gov","orcid":"https://orcid.org/0000-0001-6192-8783","contributorId":1832,"corporation":false,"usgs":true,"family":"Stanley","given":"Richard","email":"rstanley@usgs.gov","middleInitial":"G.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":293895,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brandt, Theodore R. 0000-0002-7862-9082 tbrandt@usgs.gov","orcid":"https://orcid.org/0000-0002-7862-9082","contributorId":1267,"corporation":false,"usgs":true,"family":"Brandt","given":"Theodore","email":"tbrandt@usgs.gov","middleInitial":"R.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":293894,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}
