The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set o

The U.S. Geological Survey is studying Lake Koocanusa, a border reservoir between British Columbia in Canada and Montana, in collaboration with the Montana Department of Environmental Quality and the U.S. Environmental Protection Agency (Region 8). This work is part of a multi-agency project to apply an ecosystem-scale selenium modeling methodology (Presser and Luoma, 2010) to the lake to support

Time-series data of velocity, pressure, turbidity, conductivity, and temperature were collected near the mouth of the Elwha River, Washington, USA, from December 2010 through October 2014, for the Department of Interiors Elwha River Restoration project. As part of this project, the U.S. Geological Survey studied the effects of renewed sediment supplies on the coastal ecosystems before, during, and

Field measurements of water depth were collected from the Niobrara River, a dynamic, sand-bed channel in northern Nebraska, in November 2012 and again in August 2016 to support research on remote sensing of rivers, particularly retrieval of water depth and tracking of mobile bedforms. These data were obtained by conducting topographic surveys with Trimble R8 and R10 RTK GPS receivers with a local

Avian point count, vegetation, and management data from surveys in Northern New England at four National Wildlife Refuges (NWRs), Baxter State Park, and prviate lands in Northern Maine surveyed during the breeding and postbreeding season bewteen 1 June and 4 August 2013 to 2015. NWRs include Nulhegan (Silvio O. Conte), Umbagog, Moosehorn, and Aroostook. This data release includes five zip folders

Grassland birds are among the most imperiled bird guilds in North America. Scaled quail (Callipepla squamata) are a semi-arid grassland bird whose populations have declined over the past half century. We monitored scaled quail in New Mexico to study the effects of habitat, temperature and precipitation on survival of scaled quail adults, nests, and broods. Seasonal nest survival (39.4%) had a posi

Winter-spring nitrogen loads as measured at the Susquehanna River at Conowingo Maryland and Potomac River at Washington, D.C. have been determined to be an effective indicator of summer anoxic and hypoxic volume in Chesapeake Bay. The U.S. Geological Survey (USGS) provides an estimate of winter-spring nitrogen loadings to support an annual forecast of summer Chesapeake Bay conditions. The specific

The U.S. Geological Survey collected field spectra collected from the Niobrara River in Nebraska August 15-18, 2016, to support research on remote sensing of river discharge. Reflectance measurements were made by wading the Niobrara River near Norden Notch using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The original *.asd files are provided in this d

Hyperspectral image data from the Niobrara River, a dynamic, sand-bed channel in northern Nebraska, were acquired in November 2012 and again in August 2016 to support research on remote sensing of rivers, particularly retrieval of water depth and tracking of mobile bedforms. These data were collected by the Compact Airborne Spectrographic Imager (CASI) 1500H manufactured by ITRES Research Limited.

The U.S. Geological Survey acquired hyperspectral image data and various field measurements from a reach of the Deschutes River near Bend, OR, between Benham Falls and Dillon Falls July 26-29, 2016, to support research on remote sensing of river discharge. This parent data release includes links to child pages for the following data sets: 1) hyperspectral image data; 2) ground-based bathymetric s

Hyperspectral image data and various field measurements were acquired from a reach of the Snake River in Grand Teton National Park, WY, August 19-24, 2015, to support research on remote sensing of rivers. This parent data release includes links to child pages for the following data sets: 1) hyperspectral image data; 2) ground-based depth measurements obtained by wading and with with an acoustic D

The U.S. Geological Survey (USGS) is providing online maps of water-table and potentiometric-surface altitude in the upper glacial, Magothy, Jameco, Lloyd, and North Shore aquifers on Long Island, New York, April-May 2016. Also provided is a depth-to-water map for Long Island, New York, April-May 2016. The USGS makes these maps and geospatial data available as REST Open Map Services (as well as HT
