All Data

This dataset contains Mysis count and length measurements from vertical whole-column net tows along a depth gradient in Lake Ontario and associated operation data. Sample dates occurred during August 2021 and June, July, and August 2022. Site depths ranged from 70 to 202 meters bottom depth. Sites were sampled using a paired day-night sampling approach. At each visit, the net was lowered...

This dataset contains rasters of vegetation refugia and habitat exposure variables for the state of California. Two potential future climate scenarios were used: warmer and wetter (CNRM-CM5), and hotter and drier (MIROC-ESM) & 2 emission scenarios: a higher level one that represents our current trajectory (RCP 8.5) and a lower level one that represents a more optimistic scenario (RCP 4.5...

This dataset provides sample data and NCBI accession information for genomic sequencing of Gray-headed Chickadee and Boreal Chickadee from North America and Russia.

Ground reference data in the form of ecogeomorphic evaluations, topographic survey measurements, and geotagged photographs were collected at four areas of interest (AOI) across Fire Island National Seashore (FIIS), NY, USA September 16-19, 2024, that document site conditions. The overall goals of USGS personnel for the data collection were to: (1) collect ground reference data that...

Two digital video cameras (CACO-02) were installed at Marconi Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras faced north-east (c1) and east (c2) along the beach and every half hour during daylight hours. They ran daily from March through June 2021, Feburary...

A digital video camera was installed at Marconi Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The camera faced north-east along the beach and every hour during daylight hours, daily from January 2024 to September 2024, the camera collected raw video and produced snapshots...

This data release includes genotype data for 210 Emperor Geese collected on their breeding grounds in Alaska, specifically the Yukon-Kuskokwim Delta and the Seward Peninsula, from 2007-2022. The samples were sequenced with restriction site-associated sequencing (RAD-seq), and genotyped at 44,648 single nucleotide polymorphisms (SNPs).

This dataset provides walrus counts in 10 m by 10 m square grid cells randomly selected from a standard set of grid cells established for the study area and that intersected with previously published walrus herd outlines and overlain on aerial survey imagery. Results are provided as geospatial polygons saved in the shapefile format. These data are based on visual interpretation of...

This data set describes results for laboratory experiments to determine the efficacy of environmental DNA quantitative PCR assays for four fish species when applied to filtered water samples containing metals mobilized from thawing permafrost.

This dataset describes sequence data derived from 18S ribosomal and ribulose bisphosphate carboxylase (rbcL) DNA. Stomach contents from 190 Macoma calcarea clams were examined for this study. Clams were collected from the Bering Sea and Chukchi Sea, Alaska in 2018 and 2019 using benthic van Veen grabs.

In cooperation with the Idaho Department of Water Resources, the U.S. Geological Survey (USGS) collected groundwater levels, geophysical logs, and video logs at four newly constructed monitoring wells from the Mountain Home area, Idaho, between November 12 and November 14, 2024. The Mountain Home area is located in the western Snake River plain, 40 miles to the southeast from the state...

This digital dataset is a result from the goal within the U.S. Geological Survey’s (USGS) National Cooperative Geologic Mapping Program to convert surficial data that were previously published in non-digital format to digital, vector-based data suitable for use by the public and in USGS studies. The objective of the data conversion is to reproduce the original published mapping with...
