Near Surface Spatial Water Quality Data Matched with Satellite Imagery and Discrete Phytoplankton Data in the Lower Hudson River New York, 2021-2023 Near Surface Spatial Water Quality Data Matched with Satellite Imagery and Discrete Phytoplankton Data in the Lower Hudson River New York, 2021-2023
This data release contains phytoplankton, water-quality, and satellite data from thirteen surveys along the lower Hudson River, extending from Yonkers to Troy, New York. Data were collected between August 2021 and October 2023. These surveys included continuous water-quality measurements collected at 10-second intervals using a multiparameter sonde deployed in a boat-mounted flow-through...
Data associated with the national assessment of potential average annualized losses from tsunamis in the United States Data associated with the national assessment of potential average annualized losses from tsunamis in the United States
Data tables and data references supporting the journal article titled: "Estimated average annualized losses from potential building damage and fatalities due to earthquake-generated tsunamis in the United States." Earthquake-generated tsunamis represent substantial economic threats to states and territories in the United States (U.S.), but we are unaware of any effort to quantify...
Data associated with characterizing earthquake-hazard exposure of populations with access and functional needs in the United States Data associated with characterizing earthquake-hazard exposure of populations with access and functional needs in the United States
Data that support the journal article titled “Earthquake-hazard exposure of populations with potential access and functional needs in the United States” as described here: Earthquake response plans and earthquake early warning (EEW) systems designed for general populations may not consider potential access and functional needs (AFN) of individuals with physical, sensory, cognitive, or...
Airborne magnetic and radiometric survey, west central Utah, 2023-2024 Airborne magnetic and radiometric survey, west central Utah, 2023-2024
This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over a part of west central Utah. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating natural resources and...
Geospatial data in support of structured decision making for northeast coastal parks Geospatial data in support of structured decision making for northeast coastal parks
Salt marshes provide a range of ecosystem services, including storm protection, recreation, and commercial fishery habitat provision. The National Park Service (NPS) aims to preserve and protect salt marshes in order to achieve multiple objectives which address their mission: to preserve unimpaired the natural and cultural resources and values of their publicly held lands. Ongoing...
Compositions of ash, soil, sediment, water, and biota after the 2020 CZU Lightning Complex Wildfire, Santa Cruz Mountains, California Compositions of ash, soil, sediment, water, and biota after the 2020 CZU Lightning Complex Wildfire, Santa Cruz Mountains, California
The CZU Lightning Complex Wildfire burned 86,500 acres of forested coastal watersheds in the Santa Cruz Mountains, CA, from August 16 to September 22, 2020. Ash, soil, and stream sediment were collected and characterized as soon as sites could be safely accessed to quantify potential environmental and public hazards from wildfire-related potentially toxic metals and polycyclic aromatic
