Channel Cross Sections of the Nooksack River near North Cedarville, WA, 2017-2021 Channel Cross Sections of the Nooksack River near North Cedarville, WA, 2017-2021
This data release contains channel cross sections of the Nooksack River near North Cedarville, WA, collected during routine streamgaging and discharge measurement efforts at USGS streamgage 12210700. All cross sections were collected using an acoustic doppler current profiler (ADCP) from the downstream side of the Highway 542 bridge. Raw ADCP measurement data were processed using a...
Channel steepness and chi data for part of the northern San Francisco Bay Region including parts of the Russian River and Cache Creek watersheds, northern California Channel steepness and chi data for part of the northern San Francisco Bay Region including parts of the Russian River and Cache Creek watersheds, northern California
The California Coast Range are an area with a long-lived deformation history which includes modern, ongoing right lateral strike slip faulting. Large strike slip faults in the region include the San Andreas fault, the Maacama fault, the Bartlett Springs fault among many others. In areas where strike slip fault geometry changes, either in restraining or releasing bends, vertical motion...
Characterizing projected future (2056-95) droughts in south Florida based on the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 Characterizing projected future (2056-95) droughts in south Florida based on the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5
The South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS) have evaluated projections of future (2056-95) droughts for south Florida based on climate model output from the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 (CMIP5). The emission scenarios evaluated include...
Cheatgrass and Medusahead annual Phenology extraction in Snake River Plain and Northern Basin and Range Cheatgrass and Medusahead annual Phenology extraction in Snake River Plain and Northern Basin and Range
Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. The cheatgrass and medusahead phenology in the Snake River Plain (SRP) and Northern Basin and Range (NBR) based on 30m near seamless Harmonized Landsat and Sentinel-2 (HLS) Normalized Difference...
Chemical and Biological Data from a Study on Evaluation of Chronic Effects of Potassium Chloride and Nickel on Survival, Growth, and Reproduction of a Unionid Mussel (Lampsilis siliquoidea) Chemical and Biological Data from a Study on Evaluation of Chronic Effects of Potassium Chloride and Nickel on Survival, Growth, and Reproduction of a Unionid Mussel (Lampsilis siliquoidea)
We conducted multiple toxicity tests to (1) evaluate the survival and growth of juvenile mussels (Fatmucket, Lampsilis siliquoidea) in a standard 4-week and a longer-term 12-week exposures following a method refined from the standard method using two common reference toxicants (potassium chloride [KCl] and nickel [Ni]); (2) evaluate reproductive endpoints from reproductive KCl and Ni...
Chemical and Biological Data from a Study on Evaluation of Survival and Growth of Fatmucket (Lampsilis siliquoidea) in Short-Term Chronic Toxicity Tests with Nickel and Ammonia Chemical and Biological Data from a Study on Evaluation of Survival and Growth of Fatmucket (Lampsilis siliquoidea) in Short-Term Chronic Toxicity Tests with Nickel and Ammonia
Short-term 7-day ammonia and nickel toxicity tests were conducted with juvenile Fatmucket. This data release reports individual biological, chemical, and water quality measurements in each toxicity test.
Chemical and isotopic compositions of gases from volcanic and geothermal areas in California Chemical and isotopic compositions of gases from volcanic and geothermal areas in California
Gas chemical and isotopic compositions are reported for samples collected from 9 volcanic and geothermal areas in California: Medicine Lake Volcano, Mount Shasta, Lassen Volcanic Center, Clear Lake Volcanic Field, Mono Lake Volcanic Field, Long Valley Caldera, Mammoth Mountain, Coso Volcanic Field, and Salton Sea Geothermal Field. Beginning in 2014, gas samples were collected as part of...
Chemical and isotopic data from wetland pond water samples collected in the Cottonwood Lake Study Area, Stutsman County, North Dakota, USA, 2015–2019 Chemical and isotopic data from wetland pond water samples collected in the Cottonwood Lake Study Area, Stutsman County, North Dakota, USA, 2015–2019
This U.S. Geological Survey data release contains chemical, isotopic, and physical data from wetland pond water samples collected at the Cottonwood Lake Study Area, Stutsman County, North Dakota, USA. Samples were collected monthly during the growing season (April or May through September) in 2015, 2016, 2017, and 2019 and in August 2018. Temperature, specific conductance, and pH were...
Chemical and physical data for sediment source tracking of streambed sediment in Black Creek, Indiana, tributary to the Maumee River and western Lake Erie, July 2019 Chemical and physical data for sediment source tracking of streambed sediment in Black Creek, Indiana, tributary to the Maumee River and western Lake Erie, July 2019
Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed from the Black Creek basin, Allen County, Indiana that was collected in July 2019. These data will be used in a sediment-source mixing model in order to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were...
Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2022 Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2022
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), organic carbon, and general water quality characteristics in Pinyon Plain Mine containment pond water, invertebrate, vegetation and sediment samples, collected in calendar year 2022.
Chemistry data from leachates of hydraulic fracturing proppants collected from southeastern New Mexico, 2018-2019 Chemistry data from leachates of hydraulic fracturing proppants collected from southeastern New Mexico, 2018-2019
Proppants used during hydraulic fracturing of oil and gas wells are manufactured to maximize petroleum yield by controlling the size, shape, density, and strength of the proppant material. The most common types of proppants are mined silica sand and manufactured ceramics, some of which are further modified with organic resin coatings to improve performance. Much of the work on the...
Chesapeake Bay Tidal Shoreline, Chesapeake Bay Program Phase 7 Model Chesapeake Bay Tidal Shoreline, Chesapeake Bay Program Phase 7 Model
This polygon dataset represents the tidal water shoreline of the Chesapeake Bay and its tributaries. It is based primarily on shoreline data with horizontal positional accuracy of +/- 2meters provided by the Virginia Institute of Marine Science (VIMS) Center for Coastal Resources Management (CCRM), with minor modifications in seven locations. In six instances, the modifications were made...
