Organic Geochemical Analysis Results Derived from Sediment Core Data Collected in 2021 from Siskiwit Bay, Lake Superior, Wisconsin, USA Organic Geochemical Analysis Results Derived from Sediment Core Data Collected in 2021 from Siskiwit Bay, Lake Superior, Wisconsin, USA
This dataset contains geochemical, isotopic, and biomarker data derived from sediment cores collected in Siskiwit Bay, Lake Superior, Wisconsin, USA. The dataset supports the reconstruction of historical phytoplankton communities, including cyanobacterial blooms, and environmental conditions over the past ~5,400 years. Measurements include carotenoid and chlorophyll pigments (via high...
Aerial images used to test a sundial method for inferring image acquisition time from shadow orientation Aerial images used to test a sundial method for inferring image acquisition time from shadow orientation
This data release provides aerial images acquired through the National Agricultural Imagery Program (NAIP) used to test a method for inferring image acquisition time from shadow orientation. For many applications, such as linking remotely sensed data to streamflow recorded at a gaging station, knowing the time an image is acquired is important, but such metadata often is not available...
Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis
We conducted nineteen acute toxicity assays to address knowledge gaps associated with nine critical elements: cerium (Ce), cobalt (Co), indium (In), lanthanum (La), lithium (Li), neodymium (Nd), osmium (Os), platinum (Pt), and praseodymium (Pr). Acute aquatic exposures of these elements were conducted with five organisms: an amphipod (Hyalella azteca), a mussel (Lampsilis siliquoidea), a...
Beach Profile Data Collected From Dorado, Puerto Rico Beach Profile Data Collected From Dorado, Puerto Rico
This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Dorado, Puerto Rico. Data were collected from 2022-2024 on foot by a person equipped with a Global Navigation Satellite System (GNSS) receiver and antenna affixed to a backpack outfitted for surveying location and elevation data...
Electrical resistivity tomography at Installation Restoration Site 1119 at Camp Pendleton, San Diego County, California, 2024 Electrical resistivity tomography at Installation Restoration Site 1119 at Camp Pendleton, San Diego County, California, 2024
Marine Corps Base (MCB) Camp Pendleton is an approximately 125,000 acre facility located in coastal southern California between the Los Angeles and San Diego metropolises. Established in 1942, historical military activities on the MCB Camp Pendleton have resulted in the release of environmental contaminants at numerous sites. To mitigate the risk to human health and the environment at...
USGS Dynamic Surface Water Extent (DSWE)-based Inundation Frequencies for Select U.S. Fish and Wildlife Service Mountain-Prairie Region Properties, 1982-2020 USGS Dynamic Surface Water Extent (DSWE)-based Inundation Frequencies for Select U.S. Fish and Wildlife Service Mountain-Prairie Region Properties, 1982-2020
This data release contains grids, in geographic tagged imaged file (.tif) format, summarizing inundation frequency of the U. S. Geological Survey (USGS) Dynamic Surface Water Extent (DSWE) Landsat Science Product at 114 National Wildlife Refuges throughout the U.S. Fish and Wildlife Service (USFWS) Mountain-Prairie Region (Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota...
