Historical and presettlement relationships between drought and wildfire have been well documented in much of North America, with forest fire occurrence and area burned clearly increasing in response to drought. Drought interacts with other controls (forest productivity, topography, and fire weather) to affect fire intensity and severity. Fire regime characteristics (area, frequency, severity) are the product of many individual fires, so both weather and climate - including short- and long-term droughts - are important. It is worth noting, however, that the factors controlling fire events and fire regimes are complex and extend beyond drought and climate alone, and so fire regimes and wildfires are affected by other variables from local-to-global scales. Fire history evidence from diverse climate regimes and forest ecosystems suggests that North American forest fire regimes were moderately to strongly controlled by climate prior to Euro-American settlement and subsequent fire exclusion and fire suppression (Flatley and others 2013, Hessl and others 2004, Heyerdahl and others 2002, Heyerdahl and others 2008, Swetnam 1990, Swetnam and Betancourt 1998, Weisberg and Swanson 2003). These presettlement fire histories indicate a relationship between low precipitation anomalies and widespread fire activity, especially in the Western United States. This is consistent with a regional depletion of soil and atmospheric moisture, which leads to low moisture in foliage and surface fuels and ultimately to the potential for widespread fire (Swetnam and Betancourt 1998). Some fire histories in the American Southwest also demonstrate a lagged relationship with above-average antecedent precipitation (Swetnam and Betancourt 1998) and/or cooler temperatures (Veblen and others 2000) in the year(s) prior to years of widespread fire. Most of these records are derived from fire-scarred trees that survived fire events and thus are primarily indicative of low- or mixedseverity fire regimes, although some work has focused also on evidence from high-severity fire regimes (Heyerdahl and others 2002).

There are no naturally landlocked populations, so all populations require access to fresh water and salt water to complete a natural life cycle. The species is amphidromous with use of fresh water and salt water (the estuary) varied across the species range, a pattern that may reflect whether freshwater or saltwater habitats provide optimal foraging and growth conditions. Migration is a dominant behavior during life history, beginning when fish are hatchling free embryos (southern SNS) or larvae (northeastern and far northern SNS). Migration continues by juveniles and nonspawning adult life stages on an individual time schedule with fish moving between natal river and estuary to forage or seek refuge, and by spawning adults migrating to and from riverine spawning grounds. Coastal movements by adults throughout the range (but particularly in the Gulf of Maine = GOM and among southern rivers) suggest widespread foraging, refuge use, and widespread colonization of new rivers. Colonization may also be occurring in the Potomac River, MD–VA–DC (midAtlantic region). Genetic studies (mtDNA and nDNA) identified distinct individual river populations of SNS, and recent rangewide nDNA studies identified five distinct evolutionary lineages of SNS in the USA: a northern metapopulation in GOM rivers; the Connecticut River; the Hudson River; a Delaware River–Chesapeake Bay metapopulation; and a large southern metapopulation (SC rivers to Altamaha River, GA). The Saint John River, NB, Canada, in the Bay of Fundy (north of the GOM), is the sixth distinct genetic lineage within SNS. Life history information from telemetry tracking supports the genetic information documenting extensive movement of adults among rivers within the three metapopulations. However, individual river populations with spawning adults are still the best basal unit for management and recovery planning. The focus on individual river populations should be complemented with attention to migratory processes and corridors that foster metapopulation level risks and benefits. The species may be extirpated at the center of the range, i.e., the midAtlantic region (Chesapeake Bay, MD–VA, and probably, NC), but large rivers in VA, including the James and Potomac rivers, need study. The largest SNS populations in GOM and northeastern rivers, like the Kennebec, Hudson, and Delaware rivers, typically have tens of thousands of adults. This contrasts with southern rivers, where rivers typically have much fewer (<2500) adults, except for the Altamaha River (>6000 adults). River damming in the 19th and 20th Centuries extirpated some populations, and also, created two dysfunctional segmented populations: the Connecticut River SNS in CT–MA and the SanteeCooper rivers–Lake Marion SNS in SC. The major anthropogenic impact on SNS in marine waters is fisheries bycatch. The major impacts that determine annual recruitment success occur in freshwater firstly, where adult spawning migrations and spawning are blocked or spawning success is affected by river regulation and secondly, where poor survival of early life stages is caused by river dredging, pollution, and unregulated impingement/entrainment in water withdrawal facilities. Climate warming has the potential to reduce abundance or eliminate SNS in many rivers, particularly in the South. In 1998, the National Marine Fisheries Service (NMFS) recommended management of 19 rivers as distinct population segments (DPSs) based on strong fidelity to natal rivers. A Biological Assessment completed in 2010 reaffirmed this approach. NMFS has not formally listed DPSs under the ESA and the species remains listed as endangered rangewide in the USA.","language":"English","publisher":"Wiley","doi":"10.1111/jai.13244","usgsCitation":"Kynard, B., Bolden, S., Kieffer, M., Collins, M., Brundage, H., Hilton, E., Litvak, M., Kinnison, M.T., King, T.L., and Peterson, D.C., 2016, Life history and status of Shortnose Sturgeon (Acipenser brevirostrum LeSueur, 1818): Journal of Applied Ichthyology, v. 32, no. 51, p. 208-248, https://doi.org/10.1111/jai.13244.","productDescription":"11 p.","startPage":"208","endPage":"248","ipdsId":"IP-049173","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":470303,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doi.org/10.1111/jai.13244","text":"External Repository"},{"id":350345,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","volume":"32","issue":"51","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationDate":"2017-01-16","publicationStatus":"PW","scienceBaseUri":"5a60fc66e4b06e28e9c23e22","contributors":{"authors":[{"text":"Kynard, Boyd","contributorId":197212,"corporation":false,"usgs":false,"family":"Kynard","given":"Boyd","affiliations":[],"preferred":false,"id":712954,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bolden, Stephania","contributorId":197213,"corporation":false,"usgs":false,"family":"Bolden","given":"Stephania","affiliations":[],"preferred":false,"id":712955,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kieffer, Micah 0000-0001-9310-018X mkieffer@usgs.gov","orcid":"https://orcid.org/0000-0001-9310-018X","contributorId":2641,"corporation":false,"usgs":true,"family":"Kieffer","given":"Micah","email":"mkieffer@usgs.gov","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":true,"id":712953,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Collins, Mark","contributorId":197214,"corporation":false,"usgs":false,"family":"Collins","given":"Mark","email":"","affiliations":[],"preferred":false,"id":712956,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brundage, Hal","contributorId":197215,"corporation":false,"usgs":false,"family":"Brundage","given":"Hal","email":"","affiliations":[],"preferred":false,"id":712957,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hilton, Eric","contributorId":197216,"corporation":false,"usgs":false,"family":"Hilton","given":"Eric","email":"","affiliations":[],"preferred":false,"id":712958,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Litvak, Mark","contributorId":197217,"corporation":false,"usgs":false,"family":"Litvak","given":"Mark","email":"","affiliations":[],"preferred":false,"id":712959,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Kinnison, Michael T.","contributorId":169617,"corporation":false,"usgs":false,"family":"Kinnison","given":"Michael","email":"","middleInitial":"T.","affiliations":[{"id":7063,"text":"University of Maine","active":true,"usgs":false}],"preferred":false,"id":712960,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"King, Tim L. tlking@usgs.gov","contributorId":3520,"corporation":false,"usgs":true,"family":"King","given":"Tim","email":"tlking@usgs.gov","middleInitial":"L.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":true,"id":712961,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Peterson, Douglas C.","contributorId":140154,"corporation":false,"usgs":false,"family":"Peterson","given":"Douglas","email":"","middleInitial":"C.","affiliations":[{"id":13267,"text":"Warnell School of Forestry and Natural Resources, University of Georgia","active":true,"usgs":false}],"preferred":false,"id":712962,"contributorType":{"id":1,"text":"Authors"},"rank":10}]}} ,{"id":70191678,"text":"70191678 - 2016 - A simple rubric for Stratigraphic Fidelity (β) of paleoenvironmental time series","interactions":[],"lastModifiedDate":"2017-10-25T12:42:00","indexId":"70191678","displayToPublicDate":"2016-12-31T00:00:00","publicationYear":"2016","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3481,"text":"Stratigraphy","active":true,"publicationSubtype":{"id":10}},"title":"A simple rubric for Stratigraphic Fidelity (β) of paleoenvironmental time series","docAbstract":"The Pliocene, specifically the late Pliocene, has been a focus of paleoclimate research formore than 25 years.

In the Iniskin–Tuxedni area, Detterman and Hartsock (1966) divided the formation into three mappable units including, from oldest to youngest, the Marsh Creek Breccia, the Portage Creek Agglomerate, and the Horn Mountain Tuff Members. The Horn Mountain Tuff Member was thought to include rocks deposited in a nonmarine setting based on the presence of “tree stumps in an upright position” (Detterman and Hartsock, 1966, p. 19) near the top of the type section at Horn Mountain. Bull (2015) recognized possible nonmarine volcaniclastic rocks in the member during the 2014 field season in a saddle on the north side of Horn Mountain (figs. 2-1 and 2-2). The authors visited this location in 2015 and measured a short stratigraphic section to document facies, interpret depositional setting, and constrain age.

The Sudbury River is a National Wild and Scenic River located in suburban Boston, Massachusetts (Northeastern US) with myriad impairments (e.g., mainstem impoundments, withdrawals, and urbanization) that is under increasing pressure from hydrologic alteration. We sampled fish, mussel, and macroinvertebrate assemblages in the Sudbury River and used species traits to investigate potential effects of past and future flow alteration on biota. Analysis of 33 years of stream gage data indicates continued hydrologic alteration of the Sudbury River, likely related to increased urbanization and water withdrawals over that time. These changes include a roughly 200% increase in rise rates of flows, an approximate 65% decrease in 1-day minimum flows, and a trend towards increasing high flow pulse counts. Biotic sampling in summer of 2014 demonstrated that the Sudbury River is now dominated by generalist species. Of five mussel species sampled, all are generalists in their habitat requirements. Though one mussel species of special concern was sampled, the most abundant species collected were the widespread Eastern elliptio (58%) and Eastern lampmussel (40%). We used the target fish community (TFC) model to assess the degree to which the fish assemblage deviated from that expected for a river with similar zoogeographic and physical features. Overall, the current community has a 22.7% similarity to the TFC. Of the four fluvial specialist species present in the TFC, only fallfish was sampled in our study. While the TFC showed that the historical assemblage was likely dominated by fluvial specialist and fluvial dependent species, the current assemblage is overwhelmingly dominated by macrohabitat generalists (90.6% of fishes sampled). These results are consistent with other studies that show shifts in assemblages from fluvial specialists to habitat generalists with hydrologic alteration. If the current trends continue, it is likely that biotic assemblages will experience increasing pressure from hydrologic alteration. While hydrologic alteration is likely impacting biotic assemblages in the Sudbury River, other factors such as high temperatures, low dissolved oxygen, high nutrients, low availability of high-quality habitat, and poor habitat connectivity may also be negatively impacting biotic assemblages. Comparisons to other rivers and a complete longitudinal habitat survey could help to identify availability of unique habitats and representativeness of this study. While this study suggests impacts of flow on biota, future studies with quantitative, habitat-specific sampling during different flow levels could help to directly identify links between hydrologic alteration and biotic impairment in the Sudbury River.

A hallmark of SDM is the explicit incorporation of values and science, which often includes participation from multiple stakeholders, helping to garner trust and ultimately result in a decision that is more likely to be implemented. The core steps in the SDM process are used to structure thinking about natural resources management choices, and include: (1) properly defining the problem and the decision context, (2) determining the objectives that help describe the aspirations of the decision maker, (3) devising management actions or alternatives that can achieve those objectives, (4) evaluating the outcomes or consequences of each alternative on each of the objectives, (5) evaluating trade-offs, and (6) implementing the decision. Participatory modeling for SDM includes engaging stakeholders in some or all of the steps of the SDM process listed above. In addition, participatory modeling often is crucial for creating qualitative and quantitative models of how the system works, providing data for these models, and eliciting expert opinion when data are unavailable. In these ways, SDM provides a framework for decision making in natural resources management that includes participation from stakeholder groups throughout the process, including the modeling phase.

As a result of variable beneficiation methods over the history of mining activity, these piles remain with large quantities of unrecovered Pb and Zn and to a lesser extent cadmium (Cd). Quantifying the residual content of trace metals in chat piles is problematic because of the extensive field effort that must go into collecting elevation points for volumetric analysis. This investigation demonstrates that publicly available lidar point data from the U.S. Geological Survey 3D Elevation Program (3DEP) can be used to effectively calculate chat pile volumes as a method of more accurately estimating the total residual trace metal content in these mining wastes. Five chat piles located in St. Francois County, Missouri, were quantified for residual trace metal content. Utilizing lidar point cloud data collected in 2011 and existing trace metal concentration data obtained during remedial investigations, residual content of these chat piles ranged from 9247 to 88,579 metric tons Pb, 1925 to 52,306 metric tons Zn, and 51 to 1107 metric tons Cd. Development of new beneficiation methods for recovering these constituents from chat piles would need to achieve current Federal soil screening standards. To achieve this for the five chat piles investigated, 42 to 72% of residual Pb would require mitigation to the 1200 mg/kg Federal non-playground standard, 88 to 98% of residual Zn would require mitigation to the Ecological Soil Screening level (ESSL) for plant life, and 70% to 98% of Cd would require mitigation to achieve the ESSL. Achieving these goals through an existing or future beneficiation method(s) would remediate chat to a trace metal concentration level that would support its use as a safe agricultural soil amendment.","language":"English","publisher":"AIMS Press","doi":"10.3934/environsci.2016.3.509","usgsCitation":"Witt, E.C., 2016, Use of lidar point cloud data to support estimation of residual trace metals stored in mine chat piles in the Old Lead Belt of southeastern, Missouri: AIMS Environmental Science, v. 3, no. 3, p. 509-524, https://doi.org/10.3934/environsci.2016.3.509.","productDescription":"16 p.","startPage":"509","endPage":"524","ipdsId":"IP-073845","costCenters":[{"id":5074,"text":"Center for Geospatial Information Science (CEGIS)","active":true,"usgs":true}],"links":[{"id":470298,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3934/environsci.2016.3.509","text":"Publisher Index Page"},{"id":348883,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Missouri","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -91,\n 37.39634613318923\n ],\n [\n -90.33,\n 37.39634613318923\n ],\n [\n -90.33,\n 37.94419750075404\n ],\n [\n -91,\n 37.94419750075404\n ],\n [\n -91,\n 37.39634613318923\n ]\n ]\n ]\n }\n }\n ]\n}","volume":"3","issue":"3","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5a60fc66e4b06e28e9c23e1f","contributors":{"authors":[{"text":"Witt, Emitt C.

This review synthesizes current understanding of high-latitude (≥50°N and ≥40°S) dust source geography and dynamics and provides a prospectus for future research on the topic. Although the fundamental processes controlling aeolian dust emissions in high latitudes are essentially the same as in temperate regions, there are additional processes specific to or enhanced in cold regions. These include low temperatures, humidity, strong winds, permafrost and niveo-aeolian processes all of which can affect the efficiency of dust emission and distribution of sediments. Dust deposition at high latitudes can provide nutrients to the marine system, specifically by contributing iron to high-nutrient, low-chlorophyll oceans; it also affects ice albedo and melt rates. There have been no attempts to quantify systematically the expanse, characteristics, or dynamics of high-latitude dust sources. To address this, we identify and compare the main sources and drivers of dust emissions in the Northern (Alaska, Canada, Greenland, and Iceland) and Southern (Antarctica, New Zealand, and Patagonia) Hemispheres. The scarcity of year-round observations and limitations of satellite remote sensing data at high latitudes are discussed. It is estimated that under contemporary conditions high-latitude sources cover >500,000 km2 and contribute at least 80–100 Tg yr−1 of dust to the Earth system (~5% of the global dust budget); both are projected to increase under future climate change scenarios.","language":"English","publisher":"American Geophysical Union","doi":"10.1002/2016RG000518","usgsCitation":"Bullard, J.E., Baddock, M., Bradwell, T., Crusius, J., Darlington, E., Gaiero, D., Gasso, S., Gisladottir, G., Hodgkins, R., McCulloch, R., NcKenna Neuman, C., Mockford, T., Stewart, H., and Thorsteinsson, T., 2016, High-latitude dust in the Earth system: Reviews of Geophysics, v. 54, no. 2, p. 447-485, https://doi.org/10.1002/2016RG000518.","productDescription":"13 p.","startPage":"447","endPage":"485","ipdsId":"IP-073865","costCenters":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"links":[{"id":470302,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2016rg000518","text":"Publisher Index Page"},{"id":345726,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"54","issue":"2","publishingServiceCenter":{"id":12,"text":"Tacoma PSC"},"noUsgsAuthors":false,"publicationDate":"2016-06-04","publicationStatus":"PW","scienceBaseUri":"59bb952ee4b091459a578180","contributors":{"authors":[{"text":"Bullard, Joanna E","contributorId":196439,"corporation":false,"usgs":false,"family":"Bullard","given":"Joanna","email":"","middleInitial":"E","affiliations":[],"preferred":false,"id":710355,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baddock, Matthew","contributorId":196440,"corporation":false,"usgs":false,"family":"Baddock","given":"Matthew","affiliations":[],"preferred":false,"id":710356,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bradwell, Tom","contributorId":196441,"corporation":false,"usgs":false,"family":"Bradwell","given":"Tom","email":"","affiliations":[],"preferred":false,"id":710357,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Crusius, John 0000-0003-2554-0831 jcrusius@usgs.gov","orcid":"https://orcid.org/0000-0003-2554-0831","contributorId":2155,"corporation":false,"usgs":true,"family":"Crusius","given":"John","email":"jcrusius@usgs.gov","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":710354,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Darlington, Eleanor","contributorId":196442,"corporation":false,"usgs":false,"family":"Darlington","given":"Eleanor","email":"","affiliations":[],"preferred":false,"id":710358,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Gaiero, Diego","contributorId":196443,"corporation":false,"usgs":false,"family":"Gaiero","given":"Diego","email":"","affiliations":[],"preferred":false,"id":710359,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Gasso, Santiago","contributorId":196444,"corporation":false,"usgs":false,"family":"Gasso","given":"Santiago","email":"","affiliations":[],"preferred":false,"id":710360,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Gisladottir, Gudrun","contributorId":196445,"corporation":false,"usgs":false,"family":"Gisladottir","given":"Gudrun","email":"","affiliations":[],"preferred":false,"id":710361,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Hodgkins, Richard","contributorId":196446,"corporation":false,"usgs":false,"family":"Hodgkins","given":"Richard","email":"","affiliations":[],"preferred":false,"id":710362,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"McCulloch, Robert","contributorId":196447,"corporation":false,"usgs":false,"family":"McCulloch","given":"Robert","email":"","affiliations":[],"preferred":false,"id":710363,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"NcKenna Neuman, Cheryl","contributorId":196448,"corporation":false,"usgs":false,"family":"NcKenna Neuman","given":"Cheryl","email":"","affiliations":[],"preferred":false,"id":710364,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Mockford, Tom","contributorId":196449,"corporation":false,"usgs":false,"family":"Mockford","given":"Tom","email":"","affiliations":[],"preferred":false,"id":710365,"contributorType":{"id":1,"text":"Authors"},"rank":12},{"text":"Stewart, Helena","contributorId":196450,"corporation":false,"usgs":false,"family":"Stewart","given":"Helena","email":"","affiliations":[],"preferred":false,"id":710366,"contributorType":{"id":1,"text":"Authors"},"rank":13},{"text":"Thorsteinsson, Throstur","contributorId":196451,"corporation":false,"usgs":false,"family":"Thorsteinsson","given":"Throstur","email":"","affiliations":[],"preferred":false,"id":710367,"contributorType":{"id":1,"text":"Authors"},"rank":14}]}} ,{"id":70189834,"text":"70189834 -

The RC frames with masonry infills are commonly constructed in urban and semi-urban areas. Most of these buildings are three to five stories high, and most privately owned buildings are non-engineered. High rise buildings (up to 17 stories high) are also found in Kathmandu, but their number is limited. Burnt clay bricks are widely used as masonry infill walls; external walls are generally one full brick thick (~ 230 mm), and internal walls are one half brick thick. URM bearing wall buildings are an obvious choice for the population in rural areas and the outskirts of cities, primarily to limit the material expenses. Such buildings are generally two to four stories high and constructed using burnt clay brick masonry or stone masonry with cement, lime, or mud mortar. In some of the older constructions, a different mortar known as Vajra (a mix of lime and brick dust) is also observed. These buildings have either wooden or reinforced concrete flooring. A hybrid type of construction also prevails in semi-urban and rural areas, where wood frames are used in the ground story front façade, and rest of the house is made of unreinforced masonry bearing walls. Wood frame houses (generally two to three stories high) are also observed in rural areas where the material for such construction is easily available.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"EERI Earthquake Reconnaissance Team Report: M7.8 Gorkha, Nepal Earthquake on April 25, 2015 and its Aftershocks","largerWorkSubtype":{"id":9,"text":"Other Report"},"language":"English","publisher":"Earthquake Engineering Research Institute","usgsCitation":"Kaushik, H., Bevington, J., Jaiswal, K.S., Lizundia, B., and Shrestha, S., 2016, Buildings (EERI Earthquake Reconnaissance Team Report: M7.8 Gorkha, Nepal Earthquake on April 25, 2015 and its Aftershocks), 26 p.","productDescription":"26 p.","startPage":"5-1","endPage":"5-26","ipdsId":"IP-076061","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":344407,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Nepal","otherGeospatial":"Kathmandu Valley","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n 84.715576171875,\n 27.176469131898898\n ],\n [\n 86.0888671875,\n 27.176469131898898\n ],\n [\n 86.0888671875,\n 27.97499795326776\n ],\n [\n 84.715576171875,\n 27.97499795326776\n ],\n [\n 84.715576171875,\n 27.176469131898898\n ]\n ]\n ]\n }\n }\n ]\n}","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"597afba6e4b0a38ca2750b5b","contributors":{"authors":[{"text":"Kaushik, Hemant","contributorId":195193,"corporation":false,"usgs":false,"family":"Kaushik","given":"Hemant","email":"","affiliations":[],"preferred":false,"id":706498,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bevington, John","contributorId":195194,"corporation":false,"usgs":false,"family":"Bevington","given":"John","email":"","affiliations":[],"preferred":false,"id":706499,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jaiswal, Kishor S. 0000-0002-5803-8007 kjaiswal@usgs.gov","orcid":"https://orcid.org/0000-0002-5803-8007","contributorId":149796,"corporation":false,"usgs":true,"family":"Jaiswal","given":"Kishor","email":"kjaiswal@usgs.gov","middleInitial":"S.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":706500,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lizundia, Bret","contributorId":195195,"corporation":false,"usgs":false,"family":"Lizundia","given":"Bret","email":"","affiliations":[],"preferred":false,"id":706501,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shrestha, Surya","contributorId":150710,"corporation":false,"usgs":false,"family":"Shrestha","given":"Surya","email":"","affiliations":[{"id":18073,"text":"National Society for Earthquake Technology","active":true,"usgs":false}],"preferred":false,"id":706502,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":70197971,"text":"70197971 - 2016 - Changes in blast zone albedo patterns around new martian impact craters","interactions":[],"lastModifiedDate":"2018-11-01T15:04:16","indexId":"70197971","displayToPublicDate":"2016-12-31T00:00:00","publicationYear":"2016","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1963,"text":"Icarus","active":true,"publicationSubtype":{"id":10}},"title":"Changes in blast zone albedo patterns around new martian impact craters","docAbstract":"“Blast zones” (BZs) around new martian craters comprise various albedo features caused by the initial impact, including diffuse halos, extended linear and arcuate rays, secondary craters, ejecta patterns, and dust avalanches. We examined these features for changes in repeat images separated by up to four Mars years. Here we present the first comprehensive survey of the qualitative and quantitative changes observed in impact blast zones over time. Such changes are most likely due to airfall of high-albedo dust restoring darkened areas to their original albedo, the albedo of adjacent non-impacted surfaces. Although some sites show drastic changes over short timescales, nearly half of the sites show no obvious changes over several Mars years. Albedo changes are more likely to occur at higher-latitude sites, lower-elevation sites, and at sites with smaller central craters. No correlation was seen between amount of change and Dust Cover Index, relative halo size, or historical regional albedo changes. Quantitative albedo measurements of the diffuse dark halos relative to their surroundings yielded estimates of fading lifetimes for these features. The average lifetime among sites with measurable fading is ∼15 Mars years; the median is ∼8 Mars years for a linear brightening. However, at approximately half of sites with three or more repeat images, a nonlinear function with rapid initial fading followed by a slow increase in albedo provides a better fit to the fading behavior; this would predict even longer lifetimes. The predicted lifetimes of BZs are comparable to those of slope streaks, and considered representative of fading by global atmospheric dust deposition; they last significantly longer than dust devil or rover tracks, albedo features that are erased by different processes. These relatively long lifetimes indicate that the measurement of the current impact rate by Daubar et al. does not suffer significantly from overall under-sampling due to blast zones fading before new impact sites can be initially discovered. However, the prevalence of changes seen around smaller craters may explain in part their shallower size frequency distribution.

In aquifers that are electrically-resistive relative to adjacent layers in a horizontally stratified sequence, transmissivity has been shown to correlate with bulk transverse resistance. Conversely, in aquifers that are electrically-conductive relative to adjacent layers, transmissivity has been shown to correlate with bulk longitudinal conductance. In both cases, previous investigations have relied on small datasets (on average less than eight observations) that have yielded coefficients of determination (R2) that are typically in the range of 0.6 to 0.7 to substantiate these relations. Compared to previous investigations, this paper explores hydraulic-electrical relations using a much larger dataset. Geophysical data collected from 26 boreholes in Emirate Abu Dhabi, United Arab Emirates, are used to correlate transmissivity modeled from neutron porosity logs to the bulk electrical properties of the surficial aquifer that are computed from deep-induction logs. Transmissivity is found to be highly correlated with longitudinal conductance. An R2 value of 0.853 is obtained when electrical effects caused by variations in pore-fluid salinity are taken into consideration.

Of the six formations in the group (Detterman, 1963), the basal Red Glacier Formation is the only unit that includes fine-grained rocks in outcrop that appear to be organic-rich (fig. 3-1). In an effort to better understand the stratigraphy and source-rock potential of the Red Glacier Formation, the Alaska Division of Geological & Geophysical Surveys, in collaboration with the Alaska Division of Oil and Gas and the U.S. Geological Survey, has been investigating the unit in outcrop between Tuxedni Bay and the type section at Lateral and Red glaciers (Stanley and others, 2013; LePain and Stanley, 2015; Helmold and others, 2016 [this volume]). Fieldwork in 2015 focused on a southeast-trending ridge south of Hungryman Creek, where the lower 60–70 percent of the formation (400–500 m) is exposed and accessible, except for the near-vertical faces of three segments near the southeast end of the ridge (figs. 3-2 and 3-3). Three stratigraphic sections were measured along the ridge to document facies and depositional environments (figs. 3-3 and 3-4). Steep terrain precluded study of the upper part of the formation exposed east of the ridge. This report includes a preliminary summary of findings from the 2015 field season.

The Middle Jurassic Tuxedni Group is recognized as a major source of oil in Tertiary reservoirs (Magoon, 1994), although the potential for Tuxedni reservoirs remains largely unknown. As part of this program, five days of the 2015 field season were spent examining outcrops, largely sandstones, of the Middle Jurassic Red Glacier Formation (Tuxedni Group) approximately 6.4 km northeast of Johnson Glacier on the western side of Cook Inlet (fig. 4-1). Three stratigraphic sections (fig. 4-2) totaling approximately 307 m in thickness were measured and described in detail (LePain and others, 2016 [this volume]). Samples were collected for a variety of analyses including palynology, Rock-Eval pyrolysis, vitrinite reflectance, detrital zircon geochronology, and petrology. This report summarizes our initial impressions of the petrology and reservoir quality of sandstones encountered in these measured sections. Interpretations are based largely on hand-lens observations of hand specimens and are augmented by stereomicroscope observations. Detailed petrographic (point-count) analyses and measurement of petrophysical properties (porosity, permeability, and grain density) are currently in progress.

Existing methods for estimating the location of central places from telemetry data require user‐specified thresholds and ignore common nuances like measurement error. We present a fully model‐based approach for locating central places from telemetry data that accounts for multiple sources of uncertainty and uses all of the available locational data. Our general framework consists of an observation model to account for large telemetry measurement error and animal movement, and a highly flexible mixture model specified using a Dirichlet process to identify the location of central places. We also quantify temporal patterns in central place use by incorporating ancillary behavioral data into the model; however, our framework is also suitable when no such behavioral data exist. We apply the model to a simulated data set as proof of concept. We then illustrate our framework by analyzing an Argos satellite telemetry data set on harbor seals (Phoca vitulina) in the Gulf of Alaska, a species that exhibits fidelity to terrestrial haul‐out sites.

Recent interest in gar (Lepisosteidae) ecology and conservation led us to explore the use of mini-fyke nets to capture age-0 gar and specifically how capture is affected by lead length of the fyke net. In the summers of 2012, 2013, and 2015, mini-fyke nets with two different lead lengths (4.57 m and 9.14 m) were set at random sites in backwaters and coves of the Red River arm of Lake Texoma, Oklahoma. Mean CPUE (catch-per-unit-effort; number per net night) was significantly lower for mini-fyke nets with short leads (0.52) compared to those with long leads (1.51). Additionally, Spotted Gar (Lepisosteus oculatus) were captured at a higher rate than the other three gar species present in Lake Texoma, although this could have been an artifact of sampling location. We found that differences in length-frequency of captured gar between gear types were nearly significant, with total length ranging from 47mm to 590mm. Mini-fyke nets with longer leads increased the efficiency of sampling for age-0 gar by increasing catch rate without affecting estimates of other population parameters and appear to be useful for this purpose.

By selecting locations or habitats with many benefits (e.g., food, shelter, mates) and few costs (e.g., predators), animals improve their ability to survive and reproduce. Biologists track animal movement using radio telemetry technology to study habitat selection so they can better provide species with habitats that promote population growth. We present a curriculum in which students locate “animals” (transmitters) using radio telemetry equipment and apply math skills (use of fractions and percentages) to assess their “animal's” habitat selection by comparing the availability of habitat types with the proportion of “animals” they find in each habitat type.

These observations show that changes in the global albedo patterns of Mars take place by a combination of dust storms and strong winds. Many of the observed surface changes took place along the tracks of seasonally repeating winter dust storms cataloged by Wang and Richardson (2015). These storms tend to sweep dust towards the equator, progressively shifting albedo boundaries and continuing surface changes that began before the arrival of MGS. The largest and most conspicuous changes took place during the global dust storm of 2001 (MY 25), which blanketed Syrtis Major, stripped dust from the Tharsis region, and injected dust into Solis Planum. High wind speeds but low wind stresses are predicted in Syrtis, Tharsis and Solis by the NASA Ames GCM. Frequent changes in these regions show that dust accumulations are quickly removed by stronger winds that are not predicted by the GCM, but may result from smaller-scale influences such as unresolved topography.","language":"English","publisher":"Elsevier","doi":"10.1016/j.icarus.2016.05.023","usgsCitation":"Geissler, P.E., Fenton, L., Enga, M., and Mukherjee, P., 2016, Orbital monitoring of martian surface changes: Icarus, v. 278, p. 279-300, https://doi.org/10.1016/j.icarus.2016.05.023.","productDescription":"22 p.","startPage":"279","endPage":"300","ipdsId":"IP-054080","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":355749,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"278","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5b6fc7d7e4b0f5d57878ebf3","contributors":{"authors":[{"text":"Geissler, Paul E. pgeissler@usgs.gov","contributorId":2811,"corporation":false,"usgs":true,"family":"Geissler","given":"Paul","email":"pgeissler@usgs.gov","middleInitial":"E.","affiliations":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"preferred":true,"id":740273,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fenton, L.K.","contributorId":206378,"corporation":false,"usgs":false,"family":"Fenton","given":"L.K.","email":"","affiliations":[{"id":37319,"text":"SETI Institute","active":true,"usgs":false}],"preferred":false,"id":740274,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Enga, M.","contributorId":206379,"corporation":false,"usgs":false,"family":"Enga","given":"M.","email":"","affiliations":[{"id":37320,"text":"Macomb Community College","active":true,"usgs":false}],"preferred":false,"id":740275,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mukherjee, P.","contributorId":206380,"corporation":false,"usgs":false,"family":"Mukherjee","given":"P.","email":"","affiliations":[{"id":13342,"text":"Mesa Community College","active":true,"usgs":false}],"preferred":false,"id":740276,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70193304,"text":"70193304 - 2016 - A special issue devoted to proterozoic iron oxide-apatite (±REE) and iron oxide copper-gold and affiliated deposits of Southeast Missouri, USA, and the Great Bear Magmatic Zone, Northwest Territories, Canada: Preface","interactions":[],"lastModifiedDate":"2017-11-28T12:43:14","indexId":"70193304","displayToPublicDate":"2016-12-31T00:00:00","publicationYear":"2016","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1472,"text":"Economic Geology","active":true,"publicationSubtype":{"id":10}},"title":"A special issue devoted to proterozoic iron oxide-apatite (±REE) and iron oxide copper-gold and affiliated deposits of Southeast Missouri, USA, and the Great Bear Magmatic Zone, Northwest Territories, Canada: Preface","docAbstract":"No abstract available.

This heterogeneity is evident regionally within the same host rock, as well as within districts. Future recovery of elements associated with uranium in these deposits will be strongly dependent on mining and ore-processing methods.

The St. Francois Mountains terrane lies along the southeastern margin of Laurentia as part of the eastern granite-rhyolite province. The province formed during two major pulses of igneous activity: (1) an older early Mesoproterozoic (ca. 1.50–1.44 Ga) episode of volcanism and granite plutonism, and (2) a younger middle Mesoproterozoic (ca. 1.33–1.30 Ga) episode of bimodal gabbro and granite plutonism. The volcanic rocks are predominantly high-silica rhyolite pyroclastic flows, volcanogenic breccias, and associated volcanogenic sediments with lesser amounts of basaltic to andesitic volcanic and associated subvolcanic intrusive rocks. The iron oxide deposits are all hosted in the early Mesoproterozoic volcanic and volcaniclastic sequences. Previous studies have characterized the St. Francois Mountains terrane as a classic, A-type within-plate granitic terrane. However, our new whole-rock geochemical data indicate that the felsic volcanic rocks are effusive derivatives from multicomponent source types, having compositional similarities to A-type within-plate granites as well as to S- and I-type granites generated in an arc setting. In addition, the volcanic-hosted IOA and IOCG deposits occur within bimodal volcanic sequences, some of which have volcanic arc geochemical affinities, suggesting an extensional tectonic setting during volcanism prior to emplacement of the ore-forming systems.

Our survey area spans the Kathmandu valley and areas to the east and north of the valley. Damage of buildings in the Kathmandu valley was localized, and the percentage of the totally collapsed buildings was less than 5 %. East of the Kathmandu valley, especially in Sindhupalchok district, damage of buildings was more severe. In the center of Chautara and Bahrabise, towns in Sindhupalchok district, the percentage of the totally collapsed houses exceeded 40 %. North of the Kathmandu valley, the damage was moderate, and 20–30 % of the buildings were totally collapsed in Dhunche. Based on the past studies and our microtremor observations near the strong motion station, the H/V spectrum in Kathmandu has a peak at around 0.3 Hz, which reflects the velocity contrast of the deep sedimentary basin. The H/V spectra in Bahrabise, Chautara, and Dhunche do not show clear peaks, which suggests that the sites have stiff soil conditions. Therefore, the more severe damage outside the Kathmandu valley compared with the relatively light damage levels in the valley is probably due to the source characteristics of the earthquake and/or the seismic performance of buildings, rather than the local site conditions.","language":"English","publisher":"Springer","doi":"10.1186/s40623-016-0483-4","usgsCitation":"Yamada, M., Hayashida, T., Mori, J., and Mooney, W., 2016, Building damage survey and microtremor measurements for the source region of the 2015 Gorkha, Nepal, earthquake: Earth, Planets and Space, e117; 8 p., https://doi.org/10.1186/s40623-016-0483-4.","productDescription":"e117; 8 p.","ipdsId":"IP-070252","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":470301,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1186/s40623-016-0483-4","text":"Publisher Index Page"},{"id":355765,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Nepal","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n 84.0179443359375,\n 27.36201054924028\n ],\n [\n 85.484619140625,\n 27.36201054924028\n ],\n [\n 85.484619140625,\n 28.73394733840369\n ],\n [\n 84.0179443359375,\n 28.73394733840369\n ],\n [\n 84.0179443359375,\n 27.36201054924028\n ]\n ]\n ]\n }\n }\n ]\n}","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2016-07-13","publicationStatus":"PW","scienceBaseUri":"5b6fc7d7e4b0f5d57878ebf1","contributors":{"authors":[{"text":"Yamada, Masumi","contributorId":206385,"corporation":false,"usgs":false,"family":"Yamada","given":"Masumi","email":"","affiliations":[{"id":37321,"text":"University of Kyoto","active":true,"usgs":false}],"preferred":false,"id":740312,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hayashida, Takumi","contributorId":206386,"corporation":false,"usgs":false,"family":"Hayashida","given":"Takumi","email":"","affiliations":[{"id":34873,"text":"Building Research Institute, Tsukuba, Japan","active":true,"usgs":false}],"preferred":false,"id":740313,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mori, James","contributorId":206387,"corporation":false,"usgs":false,"family":"Mori","given":"James","affiliations":[{"id":37321,"text":"University of Kyoto","active":true,"usgs":false}],"preferred":false,"id":740314,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mooney, Walter 0000-0002-5310-3631","orcid":"https://orcid.org/0000-0002-5310-3631","contributorId":206384,"corporation":false,"usgs":true,"family":"Mooney","given":"Walter","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":false,"id":740311,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70194342,"text":"70194342 - 2016 - Modeling ancient land use and resilient forests in the Jemez Mountains","interactions":[],"lastModifiedDate":"2017-11-28T11:06:20","indexId":"70194342","displayToPublicDate":"2016-12-31T00:00:00","publicationYear":"2016","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":5568,"text":"Archaeology Southwest Magazine","active":true,"publicationSubtype":{"id":10}},"title":"Modeling ancient land use and resilient forests in the Jemez Mountains","docAbstract":"No abstract available.
