Over thousands of years the region and the river have changed ecologically due to ice retreat, lake level declines, settlement and industrialization.  Settlement and industrialization have greatly accelerated the rate of change, and the Grand Calumet River and its basin are now subject to the added effects of years of direct pollution.  For years, industries directly discharged into the waterway; and those contaminants remain locked in the sediment a century later.  In order to preserve the remaining surrounding natural areas and to improve the Grand Calumet River, buried contaminants would have to be dredged from the river.  Restoration needs to be implemented as part of the clean-up process, and recontamination should be prevented.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Proceedings of the Indiana Academy of Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Nevers, M.B., Whitman, R.L., and Gerovac, P.J., 2002, History and environmental setting of the Grand Calumet River: Proceedings of the Indiana Academy of Science, v. 108/109, p. 3-10.","productDescription":"p. 3-10","startPage":"3","endPage":"10","numberOfPages":"7","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133454,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"108/109","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a54e4b07f02db62c0a8","contributors":{"authors":[{"text":"Nevers, Meredith Becker","contributorId":35677,"corporation":false,"usgs":true,"family":"Nevers","given":"Meredith","email":"","middleInitial":"Becker","affiliations":[],"preferred":false,"id":309932,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Whitman, Richard L. rwhitman@usgs.gov","contributorId":542,"corporation":false,"usgs":true,"family":"Whitman","given":"Richard","email":"rwhitman@usgs.gov","middleInitial":"L.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":309930,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gerovac, Paul J.","contributorId":19920,"corporation":false,"usgs":true,"family":"Gerovac","given":"Paul","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":309931,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Over the past nine years considerable information has been generated on cormorant feeding ecology through the examination of approximately 12,000 pellets collected on LGI, where three distinct cormorant feeding periods, pre-chick, chick, and post-chick, are delineated by differences in diet composition and daily fish consumption. Yellow perch (</span><i>Perca flavescens</i><span>) were the major prey during pre-chick and post-chick feeding periods. Alewife (</span><i>Alosa pseudoharengus</i><span>), which move inshore to spawn in mid-June, dominated (&gt;60%) cormorant diets during the chick feeding period. Mean daily fish consumption (14.6) during the pre-chick feeding period was significantly greater than during the chick feeding (9.3) or post-chick feeding (8.0) periods. The proportion of smallmouth bass (</span><i>Micropterus dolomieu</i><span>) in the diet increased over the season (0.8% to 7.2%), while the size of bass consumed declined (214 mm to 143 mm). Forage fish (mainly alewife, three-spine sticklebacks [</span><i>Gasterosteus aculeatus</i><span>] and minnows) comprised 58% of the diet of LGI cormorants, followed by panfish (37%) (yellow perch, pumpkinseed [</span><i>Lepomis gibbosus</i><span>], rock bass [</span><i>Ambloplites rupestris</i><span>]) and gamefish (5%) (mostly smallmouth bass). On the average LGI cormorants consumed about 32.8 million fish annually, weighing about 1.4 million kilograms.

At the Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS EROS Data Center, the EOS Data and Information System (EOSDIS) is required to support heritage missions as well as Landsat 7, Terra, and Aqua. The original system concept of the early 1990'S changed as each community had its say - first the managers, then engineers, scientists, developers, operators, and then finally the general public. The systems at the LP DAAC - particularly the largest single system, the EOSDIS Core System (ECS) - are changing as experience accumulates, technology changes, and each user group gains influence. The LP DAAC has adapted as contingencies were planned for, requirements and therefore plans were modified, and expectations changed faster than requirements could hope to be satisfied. Although not responsible for Quality Assurance of the science data, the LP DAAC works to ensure the data are accessible and useable by influencing systems, capabilities, and data formats where possible, and providing tools and user support as necessary. While supporting multiple missions and instruments, the LP DAAC also works with and learns from multiple management and oversight groups as they review mission requirements, system capabilities, and the overall operation of the LP DAAC. Stakeholders, including the Land Science community, are consulted regularly to ensure that the LP DAAC remains cognizant and responsive to the evolving needs of the user community. Today, the systems do not look or function as originally planned, but they do work, and they allow customers to search and order of an impressive amount of diverse data.","conferenceTitle":"Earth Observing Systems VII","conferenceDate":"July 7-10, 2002","conferenceLocation":"Seattle, WA","language":"English","publisher":"SPIE","doi":"10.1117/12.451678","issn":"0277786X","usgsCitation":"Kalvelage, T.A., 2002, Operating the EOSDIS at the land processes DAAC managing expectations, requirements, and performance across agencies, missions, instruments, systems, and user communities, Earth Observing Systems VII, v. 4814, Seattle, WA, July 7-10, 2002, p. 380-391, https://doi.org/10.1117/12.451678.","productDescription":"12 p.","startPage":"380","endPage":"391","numberOfPages":"12","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":233223,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4814","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6e75e4b0c8380cd75662","contributors":{"editors":[{"text":"Barnes W.L.","contributorId":128354,"corporation":true,"usgs":false,"organization":"Barnes W.L.","id":536544,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Kalvelage, T.

The geochemistry of sulfur is of particular interest in the Everglades because of its link, through processes mediated by sulfate-reducing bacteria, to the production of toxic methylmercury in this wetland ecosystem. Methylmercury, a neurotoxin that is bioaccumulated, has been found in high concentrations in freshwater fish from the Everglades, and poses a potential threat to fish-eating wildlife and to human health through fish consumption. Results show that surface water in large portions of the Everglades is heavily contaminated with sulfate, with the highest concentrations observed in canals and marsh areas receiving canal discharge. Spatial patterns in the range of concentrations and δ</span><sup>34</sup><span>S values of sulfate in surface water indicate that the major source of sulfate in sulfur-contaminated marshes is water from canals draining the Everglades Agricultural Area.

The δ</span><sup>34</sup><span>S results implicate agricultural fertilizer as a major contributor to the sulfate contaminating the Everglades, but ground water under the Everglades Agricultural Area (EAA) may also be a contributing source.

The investigation was initiated as a cooperative effort between the U.S. Geological Survey and the Flandreau Santee Sioux Tribe.\r\n\r\nMembers of the Flandreau Santee Sioux Tribe have expressed concern that Tribal members residing in the city of Flandreau experience more health problems than the general population in the surrounding area. Prior to December 2000, water for the city of Flandreau was supplied by wells completed in the Big Sioux aquifer within the city of Flandreau. After December 2000, water for the city of Flandreau was supplied by the Big Sioux Community Water System from wells completed in the Big Sioux aquifer along the Big Sioux River near Egan, about 8 river miles downstream of Flandreau. There is some concern that the public and private water supplies provided by wells completed in the Big Sioux aquifer near the Big Sioux River may contain chemicals that contribute to the health problems.\r\n\r\nData compiled from other investigations provide information about the water quality of the Big Sioux River and the Big Sioux aquifer in the Flandreau area from 1978 through 2001. The median, minimum, and maximum values are presented for fecal bacteria, nitrate, arsenic, and atrazine. Nitrate concentrations of water from Flandreau public-supply wells occasionally exceeded the Maximum Contaminant Level of 10 milligrams per liter for public drinking water.\r\n\r\nFor this study, untreated-water samples were collected from the Big Sioux River in Flandreau and from five wells completed in the Big Sioux aquifer in and near Flandreau. Treated-water samples from the Big Sioux Community Water System were collected at a site about midway between the treatment facility near Egan and the city of Flandreau. The first round of sampling occurred during July 9-12, 2001, and the second round of sampling occurred during August 20-27, 2001. Samples were analyzed for a broad range of compounds, including major ions, nutrients, trace elements, pesticides, antibiotics, and organic wastewater compounds, some of which might cause adverse health effects after long-term exposure. Samples collected on August 27, 2001, from the Big Sioux River also were analyzed for human pharmaceutical compounds.\r\n\r\nThe quality of the water in the Big Sioux River and the Big Sioux aquifer in the Flandreau area cannot be thoroughly characterized with the limited number of samples collected within a 2-month period, and for many analytes, neither drinking-water standards nor associations with adverse health effects have been established. Concentrations of some selected analytes were less than U.S. Environmental Protection Agency drinking-water standards at the time of the sampling, and concentrations of most organic compounds were less than the respective method reporting levels for most of the samples.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02474","usgsCitation":"Schaap, B.D., 2002, Reconnaissance-level assessment of water quality near Flandreau, South Dakota: U.S. Geological Survey Open-File Report 2002-474, iv, 32 p., https://doi.org/10.3133/ofr02474.","productDescription":"iv, 32 p.","costCenters":[],"links":[{"id":173731,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":415111,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_54229.htm","linkFileType":{"id":5,"text":"html"}},{"id":4005,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02474/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"South Dakota","city":"Flandreau","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -96.6667,\n              44.1\n            ],\n            [\n              -96.6667,\n              43.9833\n            ],\n            [\n              -96.5333,\n              43.9833\n            ],\n            [\n              -96.5333,\n              44.1\n            ],\n            [\n              -96.6667,\n              44.1\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48d1e4b07f02db54772c","contributors":{"authors":[{"text":"Schaap, Bryan D.","contributorId":63438,"corporation":false,"usgs":true,"family":"Schaap","given":"Bryan","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":236247,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

In Chesapeake Bay, we obtained sediment cores as much as 20 m in length and used numerous radiocarbon ages measured by accelarator mass spectrometry methods to provide the first detailed chronologies of Holocene sediment accumulation in the bay. Carbon in these sediments is a complex mixture of materials from a variety of sources. Analyses of different components of the sediments show that total organic carbon ages are largely unreliable, because much of the carbon (including coal) has been transported to the bay from upstream sources and is older than sediments in which it was deposited. Mollusk shells (clams, oysters) and foraminifera appear to give reliable results, although reworking and burrowing are potential problems. Analyses of museum specimens collected alive before atmospheric nuclear testing suggest that the standard reservoir correction for marine samples is appropriate for middle to lower Chesapeake Bay. The biogenic carbonate radiocarbon ages are compatible with 210 Pb and 137 Cs data and pollen stratigraphy from the same sites. Post-settlement changes in sediment transport and accumulation is an important environmental issue in many estuaries, including the Chesapeake. Our data show that large variations in sediment mass accumulation rates occur among sites. At shallow water sites, local factors seem to control changes in accumulation rates with time. Our two relatively deep-water sites in the axial channel of the bay have different long-term average accumulation rates, but the history of sediment accumulation at these sites appears to reflect overall conditions in the bay. Mass accumulation rates at the two deep-water sites rapidly increased by about fourfold coincident with widespread land clearance for agriculture in the Chesapeake watershed.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1006/qres.2001.2285","issn":"00335894","usgsCitation":"Colman, S.M., Baucom, P., Bratton, J., Cronin, T.M., McGeehin, J., Willard, D., Zimmerman, A., and Vogt, P., 2002, Radiocarbon dating, chronologic framework, and changes in accumulation rates of holocene estuarine sediments from Chesapeake Bay: Quaternary Research, v. 57, no. 1, p. 58-79, https://doi.org/10.1006/qres.2001.2285.","productDescription":"22 p.","startPage":"58","endPage":"79","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":232907,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207730,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1006/qres.2001.2285"}],"volume":"57","issue":"1","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a93e2e4b0c8380cd810aa","contributors":{"authors":[{"text":"Colman, Steven M. 0000-0002-0564-9576","orcid":"https://orcid.org/0000-0002-0564-9576","contributorId":77482,"corporation":false,"usgs":true,"family":"Colman","given":"Steven","email":"","middleInitial":"M.","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":403525,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Baucom, P.C.","contributorId":77978,"corporation":false,"usgs":true,"family":"Baucom","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":403526,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bratton, J.F.","contributorId":94354,"corporation":false,"usgs":true,"family":"Bratton","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":403527,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cronin, T.

Since this is more than double the number of published records of shortnose sturgeon in the Chesapeake Bay between 1876 and 1995, little information has been available on distributions and movement. We used fishery dependent data collected during the reward program to determine the distribution of shortnose sturgeon in the Chesapeake Bay.

In contrast, SHE resulted in easily identifiable biozones and ensured temporal continuity within them. In general, the cluster analysis produced more zones than the SHE analysis. About 87% of the cluster zones and 64% of the SHE zones were correlated across more than one core. The average age range for correlated biozone boundaries among the three cores, based on radiocarbon dates, was 821 years using cluster analysis and 296 years using SHE.

This technique allows rapid estimation of objective, GPS-based shoreline positions over hundreds of kilometers of coast, essential for the assessment of large-scale coastal behavior. Shoreline position, defined as the cross-shore position of a vertical shoreline datum, is found by fitting a function to cross-shore profiles of laser altimetry data located in a vertical range around the datum and then evaluating the function at the specified datum. Error bars on horizontal position are directly calculated as the 95% confidence interval on the mean value based on the Student's t distribution of the errors of the regression. The technique was tested using lidar data collected with NASA's Airborne Topographic Mapper (ATM) in September 1997 on the Outer Banks of North Carolina. Estimated lidar-based shoreline position was compared to shoreline position as measured by a ground-based GPS vehicle survey system. The two methods agreed closely with a root mean square difference of 2.9 m. The mean 95% confidence interval for shoreline position was ?? 1.4 m. The technique has been applied to a study of shoreline change on Assateague Island, Maryland/Virginia, where three ATM data sets were used to assess the statistics of large-scale shoreline change caused by a major 'northeaster' winter storm. The accuracy of both the lidar system and the technique described provides measures of shoreline position and change that are ideal for studying storm-scale variability over large spatial scales.","language":"English","publisher":"Coastal Education and Research Foundation","issn":"07490208","usgsCitation":"Stockdon, H., Sallenger, A.H., List, J.H., and Holman, R., 2002, Estimation of shoreline position and change using airborne topographic lidar data: Journal of Coastal Research, v. 18, no. 3, p. 502-513.","productDescription":"12 p.","startPage":"502","endPage":"513","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":233231,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":345280,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://journals.fcla.edu/jcr/article/view/81307/78447"}],"country":"United States","state":"Maryland, North Carolina, Virginia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -75.69580078125,\n              37.47485808497102\n            ],\n            [\n              -74.92675781249999,\n              37.47485808497102\n            ],\n            [\n              -74.92675781249999,\n              38.44498466889473\n            ],\n            [\n              -75.69580078125,\n              38.44498466889473\n            ],\n            [\n              -75.69580078125,\n              37.47485808497102\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.2890625,\n              34.97600151317588\n            ],\n            [\n              -74.92675781249999,\n              34.97600151317588\n            ],\n            [\n              -74.92675781249999,\n              36.58024660149866\n            ],\n            [\n              -76.2890625,\n              36.58024660149866\n            ],\n            [\n              -76.2890625,\n              34.97600151317588\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"18","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0baae4b0c8380cd5280f","contributors":{"authors":[{"text":"Stockdon, H.F. 0000-0003-0791-4676","orcid":"https://orcid.org/0000-0003-0791-4676","contributorId":55992,"corporation":false,"usgs":true,"family":"Stockdon","given":"H.F.","affiliations":[],"preferred":false,"id":401772,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sallenger, A.

Grass carp had few noticeable effects on macrophyte communities until 19 months following stocking. After 19 months, submersed macrophytes were either completely eradicated (39% of the lakes) or not controlled (42% of the lakes) in most lakes. Intermediate control of submersed macrophytes occurred in 18% of lakes at a median stocking rate of 24 fish per vegetated surface acre. Most of the landowners interviewed (83%) were satisfied with the results of introducing grass carp. For sites where all submersed macrophytes were eradicated, average turbidity was higher (11 nephelometric turbidity units, NTU) than at sites where macrophytes were controlled to intermediate levels (4 NTU) or unaffected by grass carp grazing (5 NTU). Chlorophyll a was not significantly different between levels of macrophyte control; therefore, we concluded that most of this turbidity was abiotic and not algal. Triploid grass carp were a popular control option and effectively grazed most submersed macrophytes in Washington State.

Microbial decomposition of dissolved organic carbon (DOC) contributes to overall stream metabolism and can influence many processes in the nitrogen cycle, including nitrification. Little is known, however, about the relative decomposition rates of different DOC sources and their subsequent effect on nitrification. 2. In this study, labile fraction and overall microbial decomposition of DOC were measured for leaf leachates from 18 temperate forest tree species. Between 61 and 82% (mean, 75%) of the DOC was metabolized in 24 days. Significant differences among leachates were found for labile fraction rates (P < 0.0001) but not for overall rates (P = 0.088). 3. Nitrification rates in stream sediments were determined after addition of 10 mg C L-1 of each leachate. Nitrification rates ranged from below detection to 0.49 ??g N mL sediment-1 day-1 and were significantly correlated with two independent measures of leachate DOC quality, overall microbial decomposition rate (r = -0.594, P = 0.0093) and specific ultraviolet absorbance (r = 0.469, P = 0.0497). Both correlations suggest that nitrification rates were lower in the presence of higher quality carbon. 4. Nitrification rates in sediments also were measured after additions of four leachates and glucose at three carbon concentrations (10, 30, and 50 mg C L-1). For all carbon sources, nitrification rates decreased as carbon concentration increased. Glucose and white pine leachate most strongly depressed nitrification. Glucose likely increased the metabolism of heterotrophic bacteria, which then out-competed nitrifying bacteria for NH4+. White pine leachate probably increased heterotrophic metabolism and directly inhibited nitrification by allelopathy.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1046/j.1365-2427.2002.00776.x","issn":"00465070","usgsCitation":"Strauss, E., and Lamberti, G.A., 2002, Effect of dissolved organic carbon quality on microbial decomposition and nitrification rates in stream sediments: Freshwater Biology, v. 47, no. 1, p. 65-74, https://doi.org/10.1046/j.1365-2427.2002.00776.x.","startPage":"65","endPage":"74","numberOfPages":"10","costCenters":[],"links":[{"id":209533,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1046/j.1365-2427.2002.00776.x"},{"id":236096,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"47","issue":"1","noUsgsAuthors":false,"publicationDate":"2002-01-11","publicationStatus":"PW","scienceBaseUri":"505a05d5e4b0c8380cd50fac","contributors":{"authors":[{"text":"Strauss, E.A.","contributorId":26010,"corporation":false,"usgs":true,"family":"Strauss","given":"E.A.","email":"","affiliations":[],"preferred":false,"id":403813,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lamberti, G.

Hemlock forests throughout eastern North America have been declining because of the hemlock woolly adelgid, an exotic insect pest. We found aquatic invertebrate community structure to be strongly correlated with forest composition. Streams draining hemlock forests supported significantly more total taxa than streams draining mixed hardwood forests, and over 8% of the taxa were strongly associated with hemlock. In addition, invertebrate taxa were more evenly distributed (i.e., higher Simpson's evenness values) in hemlock-drained streams. In contrast, the number of rare species and total densities were significantly lower in streams draining hemlock, suggesting that diversity differences observed between forest types were not related to stochastic factors associated with sampling and that streams draining mixed hardwood forests may be more productive. Analysis of stream habitat data indicated that streams draining hemlock forests had more stable thermal and hydrologic regimes. Our findings suggest that hemlock decline may result in long-term changes in headwater ecosystems leading to reductions in both within-stream (i.e., alpha) and park-wide (i.e., gamma) benthic community diversity.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/f02-003","issn":"0706652X","usgsCitation":"Snyder, C., Young, J., Lemarie, D.P., and Smith, D., 2002, Influence of eastern hemlock (Tsuga canadensis) forests on aquatic invertebrate assemblages in headwater streams: Canadian Journal of Fisheries and Aquatic Sciences, v. 59, no. 2, p. 262-275, https://doi.org/10.1139/f02-003.","startPage":"262","endPage":"275","numberOfPages":"14","costCenters":[],"links":[{"id":232963,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":207766,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/f02-003"}],"volume":"59","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3b2ce4b0c8380cd622bf","contributors":{"authors":[{"text":"Snyder, C.D.","contributorId":73540,"corporation":false,"usgs":true,"family":"Snyder","given":"C.D.","email":"","affiliations":[],"preferred":false,"id":402732,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Young, J.A. 0000-0002-4500-3673","orcid":"https://orcid.org/0000-0002-4500-3673","contributorId":37674,"corporation":false,"usgs":true,"family":"Young","given":"J.A.","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":402730,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lemarie, D.

These faults are on the upper plate of a subduction zone ~350-450 km inboard of the paleotrench. In southwestern Alaska, dextral displacement is 134 km on the Denali fault, at least 88-94 km on the Iditarod-Nixon Fork fault, and perhaps tens of kilometers on the Dishna River fault. The strike-slip regime coincided with Late Cretaceous sedimentation and then folding in the Kuskokwim basin, and with episodes of magmatism and mineralization at ~70, ~60, and ~30 Ma. No single driving mechanism can explain all of the ~95 million-year history of strike-slip faulting. Since ~40 Ma, the observed dextral sense of strike slip has run contrary to the sense of subduction obliquity. This may be explained by northward motion of the Pacific plate driving continental margin slivers into and/or around the oroclinal bend. From 44 to 66 Ma, oroclinal rotation, perhaps involving large-scale flexural slip, may have been accompanied by westward escape of crustal blocks along strike-slip faults. However, reconstructions of this period involve unproven assumptions about the identity of the subducting plate, the position of subducting ridges, and the exact timing of oroclinal bending, thus obscuring the driving mechanisms of strike slip. Prior to 66 Ma, oblique subduction is the most plausible driving mechanism for dextral strike slip. Cumulative displacement on all faults of the western limb of the orocline is at least 400 km, about half that on the eastern limb; this discrepancy might be explained by a combination of thrusting and unrecognized strike-slip faulting.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1086/339531","issn":"00221376","usgsCitation":"Miller, M.L., Bradley, D., Bundtzen, T., and McClelland, W.C., 2002, Late Cretaceous through Cenozoic strike-slip tectonics of southwestern Alaska: Journal of Geology, v. 110, no. 3, p. 247-270, https://doi.org/10.1086/339531.","startPage":"247","endPage":"270","numberOfPages":"24","costCenters":[],"links":[{"id":235909,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":209452,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1086/339531"}],"volume":"110","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a44d9e4b0c8380cd66e3f","contributors":{"authors":[{"text":"Miller, Marti L. 0000-0003-0285-4942 mlmiller@usgs.gov","orcid":"https://orcid.org/0000-0003-0285-4942","contributorId":561,"corporation":false,"usgs":true,"family":"Miller","given":"Marti","email":"mlmiller@usgs.gov","middleInitial":"L.","affiliations":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":403548,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bradley, Dwight 0000-0001-9116-5289 bradleyorchard2@gmail.com","orcid":"https://orcid.org/0000-0001-9116-5289","contributorId":2358,"corporation":false,"usgs":true,"family":"Bradley","given":"Dwight","email":"bradleyorchard2@gmail.com","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true},{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":403545,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bundtzen, Thomas K.","contributorId":83560,"corporation":false,"usgs":true,"family":"Bundtzen","given":"Thomas K.","affiliations":[],"preferred":false,"id":403547,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McClelland, William C.","contributorId":194066,"corporation":false,"usgs":false,"family":"McClelland","given":"William","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":403546,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Analyses of 868 plant samples were binned into 10 groups (e.g., terrestrial riparian, freshwater phytoplankton, salt marsh) to determine whether C‐N isotopes can be used as biomarkers for tracing the origins of organic matter in this river‐marsh‐estuary complex. Variability of δ<sup>13</sup>C and δ<sup>15</sup>N was high (~5–10‰) within each plant group, and we identified three modes of variability: (1) between species and their microhabitats, (2) over annual cycles of plant growth and senescence, and (3) between living and decomposing biomass. These modes of within‐group variability obscure any source specific isotopic signatures, confounding the application of C‐N isotopes for identifying the origins of organic matter. A second confounding factor was large dissimilarity between the δ<sup>13</sup>C‐δ<sup>15</sup>N of primary producers and the organic matter pools in the seston and sediments. Both confounding factors impede the application of C‐N isotopes to reveal the food supply to primary consumers in ecosystems supporting diverse autotrophs and where the isotopic composition of organic matter has been transformed and become distinct from that of its parent plant sources. Our results support the advice of others: variability of C‐N stable isotopes within all organic‐matter pools is high and must be considered in applications of these isotopes to trace trophic linkages from primary producers to primary consumers. Isotope‐based approaches are perhaps most powerful when used to complement other tools, such as molecular biomarkers, bioassays, direct measures of production, and compilations of organic‐matter budgets.</p></div>","language":"English","publisher":"ASLO","doi":"10.4319/lo.2002.47.3.0713","usgsCitation":"Cloern, J., Canuel, E.A., and Harris, D., 2002, Stable carbon and nitrogen isotope composition of aquatic and terrestrial plants of the San Francisco Bay estuarine system: Limnology and Oceanography, v. 47, no. 3, p. 713-729, https://doi.org/10.4319/lo.2002.47.3.0713.","productDescription":"17 p.","startPage":"713","endPage":"729","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true},{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true},{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":478701,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4319/lo.2002.47.3.0713","text":"Publisher Index Page"},{"id":438882,"rank":1,"type":{"id":30,"text":"Data Release"},"url":"https://doi.org/10.5066/P98ZSO0X","text":"USGS data release","linkHelpText":"Stable isotope analysis of San Francisco Bay-Delta primary producers (1990-2000)"},{"id":235946,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -122.64862060546875,\n              37.391981943533544\n            ],\n            [\n              -121.74362182617188,\n              37.391981943533544\n            ],\n            [\n              -121.74362182617188,\n              38.238180119798635\n            ],\n            [\n              -122.64862060546875,\n              38.238180119798635\n            ],\n            [\n              -122.64862060546875,\n              37.391981943533544\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"47","issue":"3","noUsgsAuthors":false,"publicationDate":"2002-05-07","publicationStatus":"PW","scienceBaseUri":"505b9660e4b08c986b31b487","contributors":{"authors":[{"text":"Cloern, J.

Alkaline igneous rocks and associated hydrothermal deposits formed at two times. The first was during the Laramide orogeny (about 70–40&nbsp;Ma), with deposits restricted spatially to the Colorado mineral belt (CMB). Other alkaline igneous rocks and associated gold deposits formed later, during the transition from a compressional to an extensional regime (about 35–27&nbsp;Ma). These younger rocks and associated deposits are more widespread, following the Rocky Mountain front southward, from Cripple Creek in Colorado through New Mexico. All of these deposits are on the eastern margin of the Cordillera, with voluminous calc-alkaline rocks to the west. The largest deposits in the belt include Cripple Creek and those in the CMB. The most important factor in the formation of all of the gold deposits was the near-surface emplacement of relatively oxidized volatile-rich alkaline magmas. Strontium and lead isotope compositions suggest that the source of the magmas was subduction-modified subcontinental lithosphere. However, Cripple Creek alkaline rocks and older Laramide alkaline rocks in the CMB that were emplaced through hydrously altered LREE-enriched rocks of the Colorado (Yavapai) province have&nbsp;</span><sup>208</sup><span>Pb/</span><sup>204</sup><span>Pb ratios that suggest these magmas assimilated and mixed with significant amounts of lower crust. The anomalously hot, thick, and light crust beneath Colorado may have been a catalyst for large-scale transfer of volatiles and crustal melting. Increased dissolved H</span><sub>2</sub><span>O (and CO</span><sub>2</sub><span>, F, Cl) of these magmas may have resulted in more productive gold deposits due to more efficient magmatic-hydrothermal systems. High volatile contents may also have promoted Te and V enrichment, explaining the presence of fluorite, roscoelite (vanadium-rich mica) and tellurides in the CMB deposits and Cripple Creek as opposed to deposits to the south. Deep-seated structures of regional extent that formed during the Proterozoic allowed the magmas to rise to shallow crustal levels. Proterozoic sites of intrusions at 1.65, 1.4, and 1.1&nbsp;Ga were also important precursors to alkaline-related gold deposits. Many of the larger gold deposits are located at sites of Proterozoic intrusions, and are localized at the intersection of northeast-trending ductile shear zones formed during Mesoproterozoic deformation, and an important north-trending fault formed during 1.1&nbsp;Ga rifting.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s00126-001-0229-4","usgsCitation":"Kelley, K.D., and Ludington, S., 2002, Cripple Creek and other alkaline-related gold deposits in the Southern Rocky Mountains, USA: Influence of regional tectonics: Mineralium Deposita, v. 37, no. 1, p. 38-60, https://doi.org/10.1007/s00126-001-0229-4.","productDescription":"23 p.","startPage":"38","endPage":"60","numberOfPages":"23","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":233143,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, New Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -110,\n              31\n            ],\n            [\n              -102,\n              31\n            ],\n            [\n              -102,\n              42\n            ],\n            [\n              -110,\n              42\n            ],\n            [\n              -110,\n              31\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"37","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fcafe4b0c8380cd4e3a4","contributors":{"authors":[{"text":"Kelley, Karen D. kdkelley@usgs.gov","contributorId":431,"corporation":false,"usgs":true,"family":"Kelley","given":"Karen","email":"kdkelley@usgs.gov","middleInitial":"D.","affiliations":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"preferred":false,"id":402765,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ludington, Steve","contributorId":60657,"corporation":false,"usgs":true,"family":"Ludington","given":"Steve","affiliations":[],"preferred":false,"id":402766,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
