Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

USGS CoastCam CACO-01 at Head of the Meadow Beach, Cape Cod National Seashore, Massachusetts (2019 to 2024): Imagery and Calibration Data USGS CoastCam CACO-01 at Head of the Meadow Beach, Cape Cod National Seashore, Massachusetts (2019 to 2024): Imagery and Calibration Data
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...

Toxicity of 6PPD alternatives to salmonids Toxicity of 6PPD alternatives to salmonids
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...
Growth and Relative Survival of Aspen Seedling Outplanting Following High Severity Wildfire in the Southwest Growth and Relative Survival of Aspen Seedling Outplanting Following High Severity Wildfire in the Southwest
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...
qPCR data for assessing the effects of seasonality, density, and tide phase on detection of invasive European green crab eDNA in Washington state, 2022-2023 qPCR data for assessing the effects of seasonality, density, and tide phase on detection of invasive European green crab eDNA in Washington state, 2022-2023
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...
Mortality of rainbow trout and sockeye salmon exposed to 16 genotypes of infectious hematopoietic necrosis virus (Genogroups U, M) at two doses and two temperatures Mortality of rainbow trout and sockeye salmon exposed to 16 genotypes of infectious hematopoietic necrosis virus (Genogroups U, M) at two doses and two temperatures
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...
