Chemical and biological data from a study on sensitivity of a unionid mussel (Lampsilis siliquoidea) to a permitted effluent and elevated potassium Chemical and biological data from a study on sensitivity of a unionid mussel (Lampsilis siliquoidea) to a permitted effluent and elevated potassium
The data release includes data from four studies: (1) toxicity of a permitted effluent, which entered the Deep Fork River (DFR), Oklahoma, USA, to a unionid mussel (Lampsilis siliquoidea) and to 2 standard test species (cladoceran Ceriodaphnia dubia; and fathead minnow Pimephales promelas) in short-term 7-d effluent tests; (2) relative sensitivities of the 3 species to potassium (K), an...
Digital Data for the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona Digital Data for the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona
This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona, U.S. Geological Survey Open-File Report 2021-1097. The Blythe 30' x 60' quadrangle in southeastern California and southwestern Arizona displays complex geology that includes Mesozoic...
Hawaii Island forest bird phenology and morphometrics from 1994 to 2019 Hawaii Island forest bird phenology and morphometrics from 1994 to 2019
We examined data from multiple studies (1994-2020) conducted across the avian annual cycle, from multiple locations, to evaluate molt patterns and establish criteria for assignment of age and sex based on the WRP (Wolfe-Ryder-Pyle) method, or molt-cycle age classification system designed specifically for tropical species. In addition, we describe the phenologies of molt and breeding and...
Reach-scale predicted annual streamflow permanence probabilities, predicted monthly mean stream temperature for August, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest, USA (2004-2015) (ver. 2.0, January 2023) Reach-scale predicted annual streamflow permanence probabilities, predicted monthly mean stream temperature for August, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest, USA (2004-2015) (ver. 2.0, January 2023)
This dataset is a combination of annual Probability of Streamflow Permanence (PROSPER) predictions, Northwest Stream Temperature (NorWeST) predictions of monthly mean stream temperatures for August of each year, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest from the USGS database of natural monthly streamflow estimates, U.S., 2004-2015. The...
Grain-Size Data from Upper Florida Keys: Crocker Reef, FL Grain-Size Data from Upper Florida Keys: Crocker Reef, FL
Sediment samples were collected from undisturbed sections of the seafloor around Crocker Reef, Florida which is a senile, degrading barrier reef located in the northern portion of the Florida Reef Tract (Figure 1). Samples were collected from November 2017 to April 2019. The sediment sample locations were near instruments deployed during the same period to record time series of ocean...
Aerial Imagery of the North Carolina Coast: 2019-11-26 Aerial Imagery of the North Carolina Coast: 2019-11-26
The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths, in response to storm events, with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM)...
