Data Releases

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

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

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.

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

The northern Gulf of Mexico coast spans two major climate gradients and represents an excellent natural laboratory for developing climate-influenced ecological models. In this project, we used these zones of remarkable transition to develop macroclimate-based models for quantifying the regional responses of coastal wetland ecosystems to climate variation. In addition to providing important fish an

The US Geological Survey, in cooperation with the National Park Service, conducted detailed geologic mapping on 35 7.5-minute quadrangles, within a 2-mile-wide+ corridor centered on the Parkway, from BLRI (Blue Ridge Parkway) Mile Post (MP) 0 near Afton, Virginia southward to MP 218 at Cumberland Knob, approximately 1.3 km south of the Virginia - North Carolina State Line. Detailed bedrock geologi

This data set characterizes the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande Cutthroat Trout (Oncorhynchus clarkii virginalis) or have been considered potential restoration areas for the fish. The majority of these streams had no previous record of continual temperature records. When compared to Colorado water temperature criteria (Cold Tier

During 2013 and 2014 aquatic invertebrates were collected and vegetation was inventoried from sample locations distributed throughout Pool 10 and West Pool of Big Stone National Wildlife Refuge. Invertebrate sampling was conducted using aquatic activity traps and by collecting organisms from submersed vegetation. Vegetation was inventoried through a combination of visual observation and collection

The goal of this project was to primarily assess east-west connectivity across Route 67 and secondarily, north-south connectivity across Scripps Poway Parkway and Poway Road, two highly trafficked roads to the west of Route 67. We collected deer scat piles from both sides of these crossings in spring between March and June of 2015, and again in fall throughout October 2015. Collected pellets were
