Data Releases

Bird and habitat surveys were conducted in winter-flooded rice fields in the Sacramento Valley, California, USA during the fall and winters of 2021-2022 (Oct 2021 through February 2022) and 2022-2023 (December 2022 through February 2023). Rice field sampling consisted of (1) a bird survey that was followed by (2) an overall habitat assessment and (3) a more detailed habitat transect...

Two digital video cameras were temporarily installed at the U.S. Fish and Wildlife Service (USFWS) Pea Island National Wildlife Refuge (PINWR) in North Carolina (NC), as part of the DUring Nearshore Event eXperiment (DUNEX). DUNEX was a collaborative community-led experiment that took place in the fall of 2021 along the Outer Banks of NC, with the goal of improving the understanding...

This study tests the influence of environmental conditions on conversion of the maceral bituminite to a solid petroleum residuum (solid bitumen) during pyrolysis. The presence of water in sedimentary basins controls multiple processes during petroleum generation, migration, and storage. Four organic-rich (26–36 wt.% total organic carbon) oil shale samples were collected from thin-bedded...

Microbial biofilm communities are composed of fungi, bacteria, and phytoplankton taxonomic groups (e.g., cyanobacteria, diatoms, and chlorophytes), which inhabit the surface of intertidal mudflats. Such biofilms have critical roles in shorebird diets, mudflat stabilization, primary productivity, and carbon storage. These raster datasets represent the presence, nutritional quality...

Model hindcasts were performed with a spectral wave model to quantify nearshore wave parameters along the Columbia River littoral cell, Oregon and Washington. The spectral wave model SWAN was used to simulate nearshore wave dynamics at 1-hr intervals along the coast between 2014 and 2023. A second hindcast simulated wave dynamics between 2010 and 2011. This data release describes the...

Geochemical data for aqueous, mine tailings, and sediment samples collected from the Big River and Meramec River drainage basins in southeastern Missouri are presented. The Big River drains historical lead, zinc, and barite mining districts, including the Old Lead Belt (OLB). Underground mining in the OLB resulted in large mine-waste chat piles and tailings impoundments that have...

These data include in situ images of lake trout (Salvelinus namaycush) and round goby (Neogobius melanostomus) collected by an autonomous underwater vehicle (AUV) in Lakes Michigan and Superior in 2020 and 2021 and laboratory images of round goby collected by a GoPro in 2021. These images were collected and labeled to train and validate an algorithm for automated fish sizing and biomass...

The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common...

This data release supersedes Pierce, J.R., Feyrer, F., Young, M., Enos, E., Clause, J., Alpers, C., and Eagles-Smith, C.A., 2022, Mercury in fishes from Clear Lake, California, 2019 and 2020 (ver. 2.0, February 2022): U.S. Geological Survey data release, https://doi.org/10.5066/P96912PN. Please contact fresc_outreach@usgs.gov for access. Comma-separated values (.csv) file containing data...

These data describe demographic (e.g, age), morphometric (body shape), and meristic (total number of gill rakers) measurements of a probable spawning run of cisco (Coregonus artedi) collected from the Spanish River (Ontario, Canada) immediately downstream of the Espanola Dam from 15-16 November 2022. These data were used to provide baseline biological, demographic, and morphological...

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They...

Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black...
