Contaminants in bed sediment from surface waters collected in the Chesapeake Bay Watershed, 2021-24 Contaminants in bed sediment from surface waters collected in the Chesapeake Bay Watershed, 2021-24
This data release provides contaminant data from bed sediment collected from small streams between 2021 and 2024 in the Chesapeake Bay Watershed. These data are part of a larger study designed to determine how conservation practices are affecting local stream ecosystem health, which stressors are negatively impacting streams, and which landscape characteristics are associated with better...
Lidar-Derived Hydrography in the Karner Brook Watershed, Massachusetts Lidar-Derived Hydrography in the Karner Brook Watershed, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the Green Berkshires, Inc., has compiled Geographic Information Systems (GIS) datasets consisting of raster and vector data used to generate lidar-derived hydrography. The spatial data layers provided in this data release are hydrography data derived from high-resolution lidar digital elevation models (DEM). The vector data are in...
Macroinvertebrate communities in PA and MD Piedmont mixed agricultural streams, 2023 Macroinvertebrate communities in PA and MD Piedmont mixed agricultural streams, 2023
From 12 May – 18 May 2023, a Virginia Tech team of 2-3 sampled the macroinvertebrate community in 30 Upper Northern Piedmont streams (Maryland and Pennsylvania, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, fish community, and fish health at the same 30 streams. Macroinvertebrates were sampled using a 500...
Scanned Recordings of the Rangely, Colorado (USA) Earthquake Control Experiment (1972) Scanned Recordings of the Rangely, Colorado (USA) Earthquake Control Experiment (1972)
These are scanned recordings from the Rangely earthquake control experiment that took place from 1969-1974 in the area surrounding Rangely, Colorado. Data were telemetered to Menlo Park, California, where they were recorded on develocorder films. Twelve stations with a total of fourteen channels were recorded and are available in this data set. Data were collected by the US Geological...

This dataset contains Round Goby (Neogobius melanostomus) capture data from surveys conducted on parts of the Champlain Canal and upper Hudson River, and adjacent areas, in New York during 2022, 2023, and 2024. The data are in two files: the first (InvasionFrontGoby_SiteData.csv) contains site location information, and the second (InvasionFrontGoby_SurveyData.csv) contains the number of...
Algal community composition and associated fish eDNA in southern Lake Michigan shoreline deposits (2024) Algal community composition and associated fish eDNA in southern Lake Michigan shoreline deposits (2024)
This data set includes information on algae community composition and metadata for fish environmental DNA (eDNA) samples collected along the shoreline of southern Lake Michigan in late August 2024. Washed up, floating, and attached algae were collected along shore and in wadable water. Algal community observations were performed by microscopy to determine primary and secondary dominance...
Lithologic logs and photographs of cores from the Atlantic Coastal Plain Lithologic logs and photographs of cores from the Atlantic Coastal Plain
Coring of Atlantic Coastal Plain sediments has long been the basis of many projects funded by the National Cooperative Geologic Mapping Program. Over the past 50 years, more than 50 cores have been obtained, and accompanying geologic field notes (lithologic logs) and photographs were made by various geologists at the time of coring. These lithologic logs and photographs provide a record...
Raman spectra, electron probe microanalysis results, and images for burbankite from the Rocky Boy stock, Bears Paw Mountains, Montana Raman spectra, electron probe microanalysis results, and images for burbankite from the Rocky Boy stock, Bears Paw Mountains, Montana
This U.S. Geological Survey data release is a collection of Raman spectra, electron probe microanalytical results, and images for burbankite [(Na,Ca)3(Sr,Ba,Ce)3(CO3)5] from the type locality at the Rocky Boy stock, Bears Paw Mountains, Montana. Burbankite was described by Pecora and Kerr (1953) for the first time from samples collected in the Bears Paw Mountains (in their publication...
