Suspended Sediment and Water Temperature Data in the Suiattle River and the Downey Creek Tributary, Washington for select time periods over 2013 - 2017 Suspended Sediment and Water Temperature Data in the Suiattle River and the Downey Creek Tributary, Washington for select time periods over 2013 - 2017
This data release provides suspended-sediment (concentration and load) and water temperature data for two locations along the Suiattle River (USGS 1217900 and 12188380) and a tributary, Downey Creek (USGS 1217985) in Washington State for partial periods over 2013-2017. Suspended-sediment and water temperature data were collected over two summer seasons from May through September 2016 and...
Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos) Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos)
This data set is composed of data collected from an experimental study inoculating mallard ducks (Anas platyrhynchos) with Saxitoxin and associated control ducks. Data includes the specific of inoculation, observational behavioral data, daily weights, dosing, results of inoculation, testing of samples collected throughout the study, and necropsy results.
2020 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York (ver. 2.0, February 2024) 2020 Hydrologic Data Summary for the Central Pine Barrens Region, Suffolk County, New York (ver. 2.0, February 2024)
This U.S. Geological Survey data release provides surface-water quality, streamflow, and groundwater-elevation data collected within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2019 through September 30, 2020. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a five-year...
Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA
To aid in geologic studies of sediment transport and environmental change of a coastal marsh, 1-centimeter (cm) foraminiferal subsamples were taken from seven sediment push cores collected in the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi (MS), in October 2016. The push cores were collected along two, shore-perpendicular transects at 5, 15, 25, and 50 meters (m)...
Mississippi National River and Recreation Area (MISS) Multibeam Bathymetry, Hillshades, and Sidescan Image Mosaics; River Velocity and Bed Composition Mapping for Hidden Falls Mississippi National River and Recreation Area (MISS) Multibeam Bathymetry, Hillshades, and Sidescan Image Mosaics; River Velocity and Bed Composition Mapping for Hidden Falls
The National Park Service's (NPS) Mississippi National River and Recreation Area (MISS) and the St. Croix National Scenic Riverway (SACN) have established high value habitat corridors for threatened and endangered native mussels, including the Winged Mapleleaf and Higgins’ Eye Pearlymussel. Underwater sonar, a hydroacoustic remote sensing technology, is a valuable tool for mapping...
St. Croix National Scenic Riverway (SACN): Sonar Data Mapping to Assess Native Mussel Habitat St. Croix National Scenic Riverway (SACN): Sonar Data Mapping to Assess Native Mussel Habitat
The National Park Service (NPS) partnered with the U.S. Geological Survey (USGS) to collect hydroacoustic data of the Saint Croix River for the development of high-resolution bathymetry and sidescan imagery. The combined datasets will provide key components to characterizing benthic habitat. These information needs were highly desired by the NPS to more accurately assess environmental...
