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.

Colorado River Project: Average growing season evapotranspiration and vegetation index remote-sensing data for the riparian corridor of the Colorado River Delta in Mexico from 2000-2020 Colorado River Project: Average growing season evapotranspiration and vegetation index remote-sensing data for the riparian corridor of the Colorado River Delta in Mexico from 2000-2020
These data were compiled for evaluating river-reach level plant water use, or evapotranspiration (ET), and vegetation greenness, or Normalized Difference Vegetation Index (NDVI), in the riparian corridor of the Colorado River delta as specified under Minute 319 of the 1944 Water Treaty. The seven reach areas from the Northerly International Boundary (NIB) to the end of the delta at the...
Estimated monthly water use for irrigation by 12-digit hydrologic unit in the conterminous United States for 2015 Estimated monthly water use for irrigation by 12-digit hydrologic unit in the conterminous United States for 2015
This data release contains the output of the Irrigation Water Use Estimation Disaggregation and Downscaling Model (IWUEDD) along with the scripts and data resources (IWUEDD_basic.zip) required to replicate the output results. The IWUEDD is used to estimate monthly irrigation withdrawals and consumptive use for each 12-digit hydrologic unit code (HUC 12) subwatershed in the conterminous...
Geochemical data including mercury for subsamples of deep cores from the Cache Creek Settling Basin, Yolo County, California Geochemical data including mercury for subsamples of deep cores from the Cache Creek Settling Basin, Yolo County, California
Sediment cores were collected in the Cache Creek Settling Basin (CCSB), Yolo County, California, during October 2011 at 10 locations (borehole sites) and during August 2012 at 5 other locations. Total core depths ranged from approximately 4.6 to 13.7 meters (15 to 45 feet), with penetration to about 9.1 meters (30 feet) at most locations. Detailed subsampling (3-centimeter intervals) was...
Mercury and Methylmercury Stable Isotope Measurements in Giant Petrels Mercury and Methylmercury Stable Isotope Measurements in Giant Petrels
Methylmercury (MeHg) and total mercury (HgT) stable isotope measurements were made by the USGS Mercury Research Lab (MRL) in different organs on the Giant Petrels (Macronectes spp.) to examine internal mercury cycling in these seabirds. These data were collected as a compliment to x-ray spectroscopy measurements made by the University of Grenoble, France. The tissues and feathers of the...
Precipitation, air temperature, streamflow, and water table depths from selected wells at the Panola Mountain Research Watershed, 2001 - 2003 Precipitation, air temperature, streamflow, and water table depths from selected wells at the Panola Mountain Research Watershed, 2001 - 2003
This dataset contains hourly average groundwater level time-series for 19 monitoring wells at the Panola Mountain Research Watershed (PMRW) from January 2001 to October 2002. The data was used in a hydrologic modeling study to test a model formulation that allowed for bi-direction fluxes between groundwater and surface water in a bucket type hydrologic model. Some wells had missing data...
The Geochemistry of Mercury and Other Constituents in Redox Manipulated Sediment cores from Clear Lake, Lake County, California The Geochemistry of Mercury and Other Constituents in Redox Manipulated Sediment cores from Clear Lake, Lake County, California
Clear Lake, located within the Coast Range west of California's Central Valley, is the largest natural freshwater lake contained fully within the state and geologically is considered to be the oldest lake in North America. Clear Lake is popular for recreation and provides critical habitat to a wide variety of fish and bird species. Water quality in Clear Lake is degraded by both by...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2020 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2020
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2020. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
Model Output Tabular Summaries for Central Valley Water and Land Use Futures: Land Use Change, Flooded Area, and Flooded Habitat Change Model Output Tabular Summaries for Central Valley Water and Land Use Futures: Land Use Change, Flooded Area, and Flooded Habitat Change
To support coordinated conservation, wetland restoration, and climate adaptation planning, we have developed five future scenarios of the Central Valley's seasonally flooded cropland and wetland waterbird habitat based on the State's most recent climate and land use projections (Wilson et al. 2021).The USGS Western Geographic Science Center and Point Blue Conservation Science modeled a...
North American Bird Banding Program Dataset 1960-2021 retrieved 2021-07-25 North American Bird Banding Program Dataset 1960-2021 retrieved 2021-07-25
The North American Bird Banding Program is directed in the United States by the U.S. Geological Survey (USGS) Bird Banding Laboratory (BBL), Eastern Ecological Science Center at the Patuxent Research Refuge (EESC) and in Canada by the Bird Banding Office (BBO), Environment and Climate Change Canada (ECCC). The respective banding offices have similar functions and policies and use the...
Model Archive Summary for acoustic derived suspended-sediment concentration at 14144700 Columbia River at Vancouver, WA Model Archive Summary for acoustic derived suspended-sediment concentration at 14144700 Columbia River at Vancouver, WA
Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Vancouver site - USGS site ID# 14144700.

Peak-flow frequency analysis for U.S. Geological Survey streamgage 06810000 Nishnabotna River above Hamburg, Iowa, in the Nishnabotna River Basin, Iowa, based on data through water year 2020 Peak-flow frequency analysis for U.S. Geological Survey streamgage 06810000 Nishnabotna River above Hamburg, Iowa, in the Nishnabotna River Basin, Iowa, based on data through water year 2020
This data release presents a peak-flow frequency analysis (Eash and others, 2013) for U.S. Geological Survey streamgage 06810000 Nishnabotna River above Hamburg, Iowa. These methods are used to provide estimates of peak-flow quantiles for 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs). Annual peak-flow data used in the peak-flow frequency analysis...
Precipitation, soil moisture, and vegetation data from 36 experimental plots in southeastern Utah, near Canyonlands National Park (2015 - 2018) Precipitation, soil moisture, and vegetation data from 36 experimental plots in southeastern Utah, near Canyonlands National Park (2015 - 2018)
These data were compiled for a study that investigated the effects of drought seasonality and plant community composition on two dominant perennial grasses, Achnatherum hymenoides (C3 photosynthesis), and Pleuraphis jamesii (C4 photosynthesis), in a dryland ecosystem. In 2015 USGS Ecologists recorded vegetation and soil moisture data in 36 experimental plots which manipulated...
