Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...

Two digital video cameras (CACO-01 c1 and c2) were installed at Head of the Meadow 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 were located near the top of the 18 meter high bluff and faced north-east (c1) and east (c2) along the beach. They ran from December...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...

Aspen stands (Populus tremuloides Michx.) are declining in western U.S. forests due to drought, changing climate, and altered disturbance regimes. Management of aspen has focused on promoting vegetative suckering, which requires viable rootstock. With increasing wildfire frequency and severity in the West, there are opportunities for aspen reforestation post-fire. We tested how deadwood...

The dataset supports studies performed in Washington state in 2022 and 2023 that investigated how detection of European green crab eDNA is affected by sampling season, green crab density, and the time at which samples are collected across a tide cycle. The data include sample site locations and descriptive categories, volume of water (L) filtered for eDNA analysis for each sampling event...

In this study, we demonstrate that infectious hematopoietic necrosis virus (IHNV), which made a host jump from sockeye salmon (Oncorhynchus nerka) to rainbow trout (O. mykiss), has not conformed to classical pathogen evolution theory. We quantified virulence in the endemic and novel hosts using common garden in vivo experiments with 16 archival IHNV isolates collected from 1972-2017...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Greater Carpathian Area. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment NAGA Project for the assessment of undiscovered oil and gas...

Game fish, sport fish, or regulated fish species are popular among recreational anglers. These species are managed by states, jurisdictions, or territories to limit their harvest and maintain healthy fish stocks. Game fish have significant economic importance and represent an essential component of fish communities. This game fish classification serves as the first public designation of...

This data release documents seven tables containing environmental tracer data and lumped parameter model results used to evaluate temporal changes in groundwater age at 268 sites across California from 2004 to 2021. These sites are spatially distributed throughout the state and represent groundwater at depths used for public supply. Each site was sampled at least twice, with paired...

The Katahdin Woods and Waters (KAWW) National Monument TFG Unit Vegetation Mapping Project was initiated in the fall of 2022 by a grant through the USGS Natural Resource Preservation Program (NRPP) to classify and map vegetation types of the TFG Unit, thereby providing resource managers and biological researchers with useful baseline vegetation information. These data provide the...

This data release presents computed tomography (CT) imagery generated from coral core samples curated within the U.S. Geological Survey (USGS) Coral-Core Archive. These data were collected as part of ongoing USGS coral-reef research activities and include samples originating from multiple locations and collection efforts. A Geotek Rotating X-ray CT (RXCT) system was used to acquire x-ray...
