Hourly Sediment Moisture Content, Salinity, and Temperature Measurements for Madeira Beach, Florida, USA (January 25 – August 31, 2023) Hourly Sediment Moisture Content, Salinity, and Temperature Measurements for Madeira Beach, Florida, USA (January 25 – August 31, 2023)
This dataset contains hourly moisture content, salinity, and temperature measurements for sediment within a dune profile at Madeira Beach, Florida, USA. The data was collected between January 25, 2023, and August 31, 2023, following impacts from Hurricane Idalia. Data were collected using 5 moisture probes that extended 90 centimeters (cm) below the surface, with sensors spaced 10 cm...
Water quality data from wetlands in North Dakota, USA, 2019 Water quality data from wetlands in North Dakota, USA, 2019
This data release describes data that were contributed to the Global Lakes Ecosystem Observation Network (GLEON) FunAqua project, a global data compilation effort. Goals of the FunAqua project are to document the drivers of global aquatic fungal diversity and determine the breadth of the niche of aquatic fungi locally, globally, and in relation to soil and leaves. Data contributed by the...
Digital elevation model of the lava dome in the crater of Mount St. Helens, April 14, 1984 Digital elevation model of the lava dome in the crater of Mount St. Helens, April 14, 1984
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is that the May 18 eruption marked the beginning of a period of eruptive activity that lasted through 1986. Beginning in October 1980, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most...
Simulated Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2023 Simulated Nutrient and Sediment Concentrations from Major Rivers in Illinois Based on Continuous Monitoring from October 1, 2015, through September 30, 2023
During water years 2016–2023 (a water year is the period from October 1 to September 30 and is designated by the year in which it ends), the U.S. Geological Survey (USGS), in cooperation with the Illinois Environmental Protection Agency (Illinois EPA), operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from...
Geochemical data for the Cenomanian-Turonian Greenhorn Formation recorded in the USGS#1 Portland Core of central Colorado Geochemical data for the Cenomanian-Turonian Greenhorn Formation recorded in the USGS#1 Portland Core of central Colorado
Geochemical and mineralogical characterization data was collected for samples of the Greenhorn Formation taken from the USGS Portland 1 core, which is stored in the USGS Core Research Center (library number E099 https://my.usgs.gov/crcwc/core/report/11834). The data was integrated with sedimentological descriptions in a manuscript (Flaum and others, 2025) that includes revised...
Industrial Waste Ditch surface sediment chemical and physical properties, Idaho National Laboratory, Idaho Industrial Waste Ditch surface sediment chemical and physical properties, Idaho National Laboratory, Idaho
The U.S. Geological Survey (USGS), in cooperation with the U.S. Department of Energy and Naval Reactors Facility (NRF), collected sediment samples along the Industrial Waste Ditch (IWD) located on the northern boundary of the NRF. Sediment samples were collected at various intervals downstream from the outfall at different positions within the ditch as well as dredge pile sediments...
