This USGS data release includes a shapefile of outlet point locations for 12-digit hydrologic units (HU12s) from the Watershed Boundary Dataset (WBD), dated August 13, 2020 (U.S. Geological Survey and others, 2020), draining to the Gulf of Mexico in the south-central and southeastern United States. The outlet locations were derived by combining the WBD boundaries with flow direction grids from the

This digital dataset contains historical geochemical and other information for 100 samples of groundwater from 71 wells located within 3 miles of the Poso Creek Oil Field in Kern County, California. An additional 12 wells in the Poso Creek study area, but co-located within 3 miles of the adjacent Rosedale and Rosedale Ranch Oil Fields, were not included in this data release; these data are planned

The National Park Service (NPS), in collaboration with the U.S. Geological Survey (USGS), recognizes the need to quantify the sediment budget of the barrier islands within the Gulf Islands National Seashore (GINS) to understand the coastal processes affecting island resiliency. To achieve this goal, identifying and quantifying the physical parameters that drive long-term change is necessary to mod

In 2016, the U.S. Geological Survey (USGS) conducted ground penetrating radar (GPR) surveys and sediment sampling at Fire Island, New York to characterize and quantify spatial variability in the subaerial geology (Forde and others, 2018). These surveys, in combination with historical data, allowed for a preliminary reconstruction of the barriers long-term evolution. In 2021, scientists from the US

Coho salmon have been shown to be highly sensitive to the tire transformation chemical 6PPD-quinone, with concentrations contained in stormwater sufficient to induce mortality in up to 90% of the entire fall coho run. Other salmonid species (chinook, sockeye, chum) are much less sensitive to 6PPD-quinone induced mortality. This data examines the varying species sensitivities across salmoids using

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River on June 21-22 and July 20, 2021, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence of dissolved organic matter were recorded

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River and St. Lucie River July 13-15, 2020 and the Caloosahatchee River September 22 and 23 of 2019, south Florida. The St. Lucie portion of the surveys was not able to be completed in September due to boat engine failure. Geo-referenced measurements of near surface water temperatu

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the St. Lucie and Caloosahatchee Rivers in October 2017, Lake Okeechobee and the Caloosahatchee River in July 2018 and the Caloosahatchee River, St. Lucie River and Lake Okeechobee in August of 2018, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, d

This data release provides data for quantifying the aquatic export of total carbon in a cypress swamp within the Big Cypress National Preserve, and is part of a larger carbon budget study. The U.S. Geological Survey operated two continuous streamflow and water-quality monitoring stations within the Big Cypress National Preserve in southern Florida from September 2015 to October 2017. Site-specific

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River, St. Lucie River and Lake Okeechobee July 15-18 and August 19-21 of 2019, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence

This data release contains meteorological sensor data (6-minute intervals) collected at Great South Bay at Watch Hill on Fire Island (USGS station number, 01305575), New York, from 2017 to 2022. Measured parameters include: air pressure, air temperature, precipitation, relative humidity, solar radiation, wind direction and speed, and wind-gust direction and speed. Data users are encouraged to revi

This U.S. Geological Survey (USGS) data release provides water-quality data collected from the Caloosahatchee River and 12 fiberglass tanks located within the Caloosahatchee River. The tanks were open to the atmosphere, and were closed to the river. Tanks were filled with native water within 1-2 hours prior to the first profile collected on May 6, July 8, and September 16.
