Documentation of the Precipitation-Runoff Modeling System and Output from the RegCM3 Regional Climate Model Used to Estimate Potential Effects of Climate Change on Streamflow for Seven Watersheds in Eastern and Central Montana (2013-2014 Analyses)
Fish in Northern Great Plains streams evolved to survive heat, cold, floods and drought; however changes in streamflow associated with long-term climate change may render some prairie streams uninhabitable for current fish species. To better understand future hydrology of these prairie streams, the Precipitation-Runoff Modeling System (PRMS) model and output from the RegCM3 Regional Climate model
Vegetation classification crosswalk database for use in GIS to synchronize vegetation map layers of the NPS Great Lakes Network to the U.S. National Vegetation Classification
The geodatabase contains 13 relate tables that together provide updated and synchronized classifications to an existing vegetation map layer for each of the nine park units in the Great Lakes Network (GLKN) of the National Park Service (NPS) Natural Resource Inventory and Monitoring Program. The classifications include 1) vegetation types at every hierarchical level in the 2015 version of the U.S.
Still-image frame grabs and benthic habitat interpretation of underwater video footage, March 2014, Faga'alu Bay, Tutuila Island, American Samoa
Underwater video imagery was collected in March 2014 in the nearshore waters of Faga'alu Bay on the Island of Tutuila, American Samoa, as part of the U.S. Geological Survey Coastal and Marine Geology Program's Pacific Coral Reefs Project. This data set includes 2,119 still images extracted from the video footage every 10 seconds and an Environmental Systems Research Institute (ESRI) shapefile with
Sediment core data from offshore Palos Verdes, California
The seven files included in this U.S. Geological Survey data release are data from a set of sediment cores acquired from the continental slope, offshore Los Angeles and the Palos Verdes Peninsula, adjacent to the Palos Verdes Fault. Gravity cores were collected by the USGS in 2009 (cruise ID S-I2-09-SC; http://cmgds.marine.usgs.gov/fan_info.php?fan=SI209SC), and vibracores were collected with the
Volcano Monitoring Data
Many volcanoes in the U.S. are monitored by arrays of several instruments that detect subtle movements within the earth and changes in gas and water chemistry. The Volcano Hazards Program streams this data to its Volcano Observatories and makes it available on volcano-specific websites.
Water-Quality Summaries for Several Major River Basins in Colorado
Summaries of water-quality monitoring data are now available for several major river basins in Colorado. For each basin, current data from a network of sites are compared to previously collected data and instream standards. Lowess curves are provided on plots for selected constituents where a sufficient period of record and limited censored data are available.
Bathymetry and Backscatter Intensity of the Sea Floor South of Long Island, New York
Surveys of the bathymetry and backscatter intensity of the sea floor south of Long Island, New York, were carried out in November 1998 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The purpose of the multibeam echosounder surveys was to explore the bathymetry and backscatter intensity of the sea floor in several areas off the southern coas
Geospatial data collected from tagged sea otters in central California, 1998-2012
The data are .csv files of tagged sea otter re-sighting locations (henceforth, resights) collected in the field using a combination of VHF radio telemetry and direct observation using high powered (80x) telescopes. Sea otters were tracked by shore based observers from the date of tagging until the time of radio battery failure or the animals death, whichever comes first. The frequency of re-sighti
Alaska Volcano Observatory - Is Ash Falling?
Reports of ash fall are important to us; we use your observations to assess the character and size of an eruption plume. We report these data to the National Weather Service so they can keep their Ashfall Advisories current. Additionally, reports of NO ashfall during an eruption with expected ashfall are also important to us.
Spectacled Eider (Somateria fischeri) Nest, Capture, and Resight Records Yukon-Kuskokwim Delta, Alaska
This dataset contains capture, measurement, and resight data from Spectacled Eiders (Somateria fischeri) near the Kashunuk River and on Kigigak Island on the Yukon-Kuskokwim Delta, Alaska since 1991. This dataset contains nest visit records of Spectacled Eiders (Somateria fischeri) near the Kashunuk River and on Kigigak Island on the Yukon-Kuskokwim Delta, Alaska since 1991.
Water-quality datasets and E. coli predictions for selected streams in the Upper Duck River Watershed, central Tennessee, 2007-2010
From October 2007 through September 2010, the U.S. Geological Survey (USGS) in cooperation with the Tennessee Duck River Development Agency monitored water quality at 24 sites in the Upper Duck River Watershed. Water samples were collected and analyzed for carbonate hardness, acid neutralizing capacity, chloride, ammonia, nitrate, nitrite, phosphorus, boron, bromine, Enterococci and Escherichia co
