Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Digital data from USGS OFR 83-250: Selected data for low-temperature (less than 90 degrees C) geothermal systems in the United States; reference data for U.S. Geological Survey Circular 892 Digital data from USGS OFR 83-250: Selected data for low-temperature (less than 90 degrees C) geothermal systems in the United States; reference data for U.S. Geological Survey Circular 892
The data in the csv and text files provided in this release are an update to the data tables originally published in USGS Open-File Report (OFR) 83-250 (https://doi.org/10.3133/cir892). Those data were published as paper tables and have until now only been available as pdf image documents that were not machine readable. USGS OFR 83-250 presented data for 2071 geothermal sites which are
Groundwater-quality data in the Northern San Joaquin Valley Domestic-Supply Aquifer Study Unit, 2019: Results from the California GAMA Priority Basin Project Groundwater-quality data in the Northern San Joaquin Valley Domestic-Supply Aquifer Study Unit, 2019: Results from the California GAMA Priority Basin Project
The U.S. Geological Survey collected groundwater samples from 46 wells used for domestic and small system drinking water supplies in San Joaquin, Calaveras, and Stanislaus counties, California in 2019. The wells were sampled for the Northern San Joaquin Valley Domestic-Supply Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and...
GSFLOW and MODSIM-GSFLOW model used to evaluate the potential effects of increased temperature on the Carson Valley watershed and agricultural system in eastern California and western Nevada GSFLOW and MODSIM-GSFLOW model used to evaluate the potential effects of increased temperature on the Carson Valley watershed and agricultural system in eastern California and western Nevada
The USGS developed an integrated river operations-groundwater model using GSFLOW and MODSIM GSFLOW to simulate streamflow derived from snowmelt, the distribution of surface water based on the existing prior appropriations water doctrine, supplemental pumping in response to surface water shortfalls, and the resulting surface water-groundwater interactions in the Carson Valley in...
Discrete Carbonate System Parameter Measurements in Middle Tampa Bay, Florida and the Eastern Gulf of Mexico, USA Discrete Carbonate System Parameter Measurements in Middle Tampa Bay, Florida and the Eastern Gulf of Mexico, USA
This data set contains time series measurements of discrete seawater samples analyzed for carbonate system and basic water quality parameters including water temperature (degrees C), salinity, pHT (pH on the total scale), total alkalinity (micromol/kg), dissolved inorganic carbon (micromol/kg), nitrate + nitrite (micromol/L), nitrite (micromol/L), silicate (micromol/L), ammonium...
Travel Time and Dissolved Oxygen Data from August 2020 Along a 1-Mile Reach of the Blue River near 58th Street, Kansas City, Missouri Travel Time and Dissolved Oxygen Data from August 2020 Along a 1-Mile Reach of the Blue River near 58th Street, Kansas City, Missouri
These data were collected during a travel time and dissolved oxygen study along a 1-mile reach of the Blue River downstream from 58th Street in Kansas City, Missouri. The study was a cooperative effort between the U.S. Geological Survey (USGS), the U.S. Environmental Protection Agency Urban Waters Federal Partnership program, and the Kansas City, Missouri, Water Services Department. This...
Lake Ontario Water Quality and Velocity Transect Data 2015-18 Lake Ontario Water Quality and Velocity Transect Data 2015-18
From May of 2015 through September of 2018, water-quality were collected at 178 locations and velocity data were collected along 7 transects from select tributaries, embayments, and nearshore lake locations along New York's Lake Ontario waterfront in support of the Great Lakes Restoration Initiative and the Lakewide Action Management Plan. These data include: depth, velocity magnitude...
Predicted Calving and Post-calving Season Resource Use of the Porcupine Caribou Herd During 2012–2018 With Future Projections for the 2030s, 2040s, and 2050s Predicted Calving and Post-calving Season Resource Use of the Porcupine Caribou Herd During 2012–2018 With Future Projections for the 2030s, 2040s, and 2050s
This dataset contains rasters and polygon shapefiles related to predicted resource use of the Porcupine Caribou Herd (PCH) during the calving (26 May-10 June) and post-calving (11-30 June) seasons in Alaska and the Yukon Territory. Resource selection was analyzed for each season using random forest models, which compared female caribou GPS collar locations (2012-2018) to available...
Landsat 8 Collection 1 cloud truth mask validation set Landsat 8 Collection 1 cloud truth mask validation set
The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 48 unique Landsat 8 Collection 1 images. These images were selected at random from the Landsat 8 archive from various locations around the world. While these validation images were subjectively designed by a single analyst, they provide...
Sea Otter Survey Data, Carcass Recovery Data, and Blood Chemistry Data from Southwest Alaska Sea Otter Survey Data, Carcass Recovery Data, and Blood Chemistry Data from Southwest Alaska
Three data sets are included here to aid in assessment of the sea otter population collapse in southwest Alaska. One data set consists of results of sea otter surveys conducted between 1959 and 2015 at Bering Island, Russia and a selection of western Aleutian Islands in Alaska. Sea otter counts are reduced to a comparable value of otters per linear kilometer. Another data set consists...
Persistent Organic Pollutants in Sea Otter Blood and in Blue Mussels from the Aleutian Islands and Southeast Alaska Persistent Organic Pollutants in Sea Otter Blood and in Blue Mussels from the Aleutian Islands and Southeast Alaska
Two data sets concerning organic contaminants are included here to aid in assessment of the sea otter population collapse in southwest Alaska. One data set consists of levels of organic pollutant compounds found in wild sea otter blood collected from captured animals in 1997 (Jessup et al., 2010). These sea otters were captured from islands in the western Aleutians and from outside the...
