Phosphorus, nitrogen, chloride, and suspended-sediment load estimates for the Great Lakes Restoration Initiative tributary monitoring network: Water years 2011–2023 Phosphorus, nitrogen, chloride, and suspended-sediment load estimates for the Great Lakes Restoration Initiative tributary monitoring network: Water years 2011–2023
Phosphorus, nitrogen, chloride, and suspended-sediment loads, in 24 U.S. tributaries of the Great Lakes, were estimated using U.S. Geological Survey (USGS) data from the Great Lakes Restoration Initiative (GLRI) monitoring program for the period Oct 2010 through Sept 2023 (USGS water years 2011-23). Specific water-quality constituents include total phosphorus, orthophosphate, particulate
Gulf of America Non-spinose Planktic Foraminifera Culture Study From 2020-2022 Gulf of America Non-spinose Planktic Foraminifera Culture Study From 2020-2022
This pilot study was intended to test whether Globorotalia truncatulinoides (G. truncatulinoides) and Globorotalia menardii (G. menardii) specimens could be successfully harvested from offshore plankton tow samples and kept alive in a laboratory at the U.S Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC). The methodologies and resources which were used to...
Satellite-derived shorelines from CoastSeg in multiple U.S. locations (1984-2023) Satellite-derived shorelines from CoastSeg in multiple U.S. locations (1984-2023)
This dataset contains shoreline positions derived from available satellite imagery for multiple locations (Barter Island, Alaska; Elwha, Washington; Cape Cod, Massachusetts; Madeira Beach, Florida; and Rincon, Puerto Rico) across the United States for the time period 1984 to 2023, to support ongoing remote-sensing development and validation efforts.
Breeding Shorebird Surveys on the Yukon-Kuskokwim Delta, Alaska, 2015-2016 Breeding Shorebird Surveys on the Yukon-Kuskokwim Delta, Alaska, 2015-2016
We conducted ground-based surveys at 589 randomly selected 16-ha plots on the Yukon-Kuskokwim Delta, Alaska during 2015-2016. The plots were selected using a stratified random sampling plan in an area of 35,769 square km divided into 8 physiographic strata. The population totals from the stratified random design estimators were adjusted using detection ratios derived with a double...
Telemetry based determination of first-year survival for lake sturgeon reintroduced to the Maumee River Telemetry based determination of first-year survival for lake sturgeon reintroduced to the Maumee River
Lake sturgeon (Acipenser fulvescens) have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, lake sturgeon were extirpated in the Maumee River watershed (Ohio, USA). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the potential success of...
Data for assessment of mineral commodity supply risk 2018 Data for assessment of mineral commodity supply risk 2018
Data for Figure 2 of U.S. Geological Survey Open-File Report 2021-1045 titled "Methodology and Technical Input for the 2021 Review and Revision of the U.S. Critical Minerals List." The data include the disruption potential, economic vulnerability, trade exposure, and overall supply risk for various mineral commodities in 2018. For some commodities, indicator scores are rounded to avoid
