Data

The data set contains sampling and catch data associated with an experiment to examine dispersal and short-term survival of endangered pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River of eastern Montana. The experiment was conducted as part of a flow test from Fort Peck Dam, when warm surface water from Fort Peck reservoir was released over the spillway to...

Endangered pallid sturgeon (Scaphirhynchus albus) spawning habitats were mapped on the Tongue River near Miles, City Montana June in 2023 and 2024. Data quantify the physical characteristics of the river channel and flow; depth, velocity and habitat assessments using single-beam sonar, acoustic Doppler current profilers (ADCPs) in 2023 and single-beam sonar in 2024. Real-time kinematic...

The Willamette River Basin encompasses 31,000 square kilometers of western Oregon and consists of twelve major subbasins, each with hundreds of individual streams and unique hydrogeomorphic regimes and river corridor conditions. In conjunction with environmental DNA (eDNA) sample collection to support occupancy modeling of native freshwater mussels across the Willamette River Basin, bed...

The dataset documents results from particle size analysis (PSA) and portable X-ray fluorescence (pXRF) analysis conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Samples denoted by "FD24-Sed" were collected to obtain representative samples of surficial geologic map units, and samples denoted by "FTD-WS-MW" were collected during a...

This digital dataset contains the gridded future climate data for the same modeled extent as the Paso Robles Groundwater Basin Model (GEOSCIENCE and Todd Groundwater, 2015). The monthly climate data for the Paso Robles Hydrologic Model are based on the Salinas and Carmel River Basins Study (SCRBS) future climate scenarios (Henson and others, 2024). SCRBS considers one baseline climate...

Underwater passive acoustic monitoring was conducted at multiple sites on rivers in the Willamette River Basin, Oregon. Hydrophones were used to record the sound associated with coarse river-bed sediment (bedload) movement. Bedload supply and transport are key factors determining channel morphology in gravel-bed rivers and can affect reach-scale conditions such as aggradation and...

The Ecology Section at the USGS Conte Laboratory has conducted individual tagging studies in a number of locations. We provide data here for three smaller studies (Sawmill river in MA, USA, Shorey brook in ME, USA, and Catamaran brook in NB, CA). The goal is to understand the strength and direction of drivers on fish growth, movement and survival in the wild. We hope to provide a...

The Ecology Section at the USGS, EESC, S. O. Conte Research Laboratory studied brook trout in a small coastal stream (Stanley Brook) from 2006 - 2013. The goal was to understand the mechanisms and consequences of anadromoy, as well as strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish

Using the horizontal-to-vertical spectral-ratio (HVSR) method, we inferred the depth to bedrock at the Slate River Floodplain, CO, USA. The point-scale passive seismic data were collected using Model TEP-3C Tromino seismometers over 20 min or less intervals with the instruments coupled directly to the floodplain ground surface at 42 non-flooded locations during June 2021. The ratio of...

Increasing trends of coral mortality is a challenge to coral reef management worldwide, and a need exists to identify the causes and pathways involved. Pathology is useful to help decipher potential causes of mortality in animals, because it illuminates agents associated with lesions and gives insights on the nature of how a host responds to said agents. To better understand the nature...

Collections for histopathology in corals require holding of samples in seawater for a time before they are fixed for histopathology processing. This could adversely affect interpretation of morphologic changes during histopathology examinations. We evaluated microscopic morphology of Porites evermanni and Montipora capitata, held (0-120 min) in seawater prior to fixation in Z-Fix...

Snake fungal disease, which is caused by the fungal pathogen Ophidiomyces ophidiicola, is associated with severe skin infections and mortality in individual snakes. However, little has been described regarding how disease severity and impacts vary by snake populations and species. We describe mortality in rainbow snakes in Virginia, USA, linked to snake fungal disease. This data set...
