The NASA SWOT satellite, which is scheduled for launch in 2020, will monitor the earths fresh water with better resolution and precision than what had previously been possible for a space-based platform. The primary SWOT measurements will be used to generate estimates of river discharge that are meant to obtain river fluxes globally at high accuracy and reach lengths of tens of kilometers, even in

A long-term study of the geomorphic history of the lower Rio Puerco arroyo in north-central New Mexico included the collection of high-precision (Real-time kinematic) GPS survey data, registration and rectification of historical aerial photographs, an aerial LiDAR survey, and acquisition of post-flood satellite imagery. Mapping of geomorphic features from the aerial photographs and satellite image

Community composition data for assessing fish populations in headwater streams of the Adirondack Mountains, New York, USA. Data were collected to assess fish communities and estimate population size and biomass for each species at each sampling site. All data collected from western portion of Adirondack Park or immediately adjacent to it. Each row represents one individual fish. This spreadsheet c

The Midwest Stream Quality Assessment is the first of several regional studies that are being conducted as part of the Regional Stream Quality Assessment (RSQA) project, a component of the Cycle 3 National Water Quality Assessment (NAWQA) project. The MSQA was a collaborative study amongst NAWQA, the USGS Columbia Environmental Research Center (CERC), and the USEPA National Rivers and Streams Asse

This dataset contains information on the physical traits and environmental tolerances of plant species occurring along the lower Colorado River through Grand Canyon. Due to the unique combination of plant species within the Grand Canyon, this flora shares species with many riparian areas in the western U.S.A. and represents obligate wetland to obligate upland plant species. Data for the matrix wer

These plant and soil data were collected by Timothy M. Wertin and Sasha C. Reed in the spring, summer, and fall of 2011 at a climate manipulation experiment site near Moab, UT (38.521411, -109.470567). These data were collected to assess how warming affects leaf photosynthesis, soil CO 2 efflux, and soil chemistry in plots of ambient and warming treatments. The purpose of these data are to documen

The National Assessment of Coastal Change Hazards project derives features of beach morphology from lidar elevation data for the purpose of understanding and predicting storm impacts to our nation's coastlines. This dataset defines mean beach slopes along the United States Northeast Atlantic Ocean for Massachusetts for data collected at various times between 2000 and 2013. For further information

Two unique datasets on the abundance and morphology of the angel lichen moth (Cisthene angelus) in Grand Canyon, Arizona, USA were compiled to describe the phenology and life history of this common, but poorly known, species. The abundance data were collected from 2012 to 2013 through a collaboration with river runners in Grand Canyon National Park. These citizen scientists deployed light traps fr

Historical shoreline surveys were conducted by the National Ocean Service (NOS), dating back to the early 1800s. The maps resulting from these surveys, often called t-sheets, provide a reference of historical shoreline position that can be compared to modern data to identify shoreline change. The t-sheets are stored at the National Archives and many have been scanned by the National Oceanic and At

These datasets provide lidar-derived topography for Anegada and a portion of the submerged environs. Elevation measurements were acquired on January 21, 2014 by an Optech Orion M300, and on March 19-20, 2014 by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B). The authors acknowledge Emily Klipp, Chris Pali, Virgil Rabine, Rudy Troche, and Wayne Wright, all formerly o

Atlantic coast piping plover (Charadrius melodus) nest sites are typically found on low-lying beach and dune systems, which respond rapidly to coastal processes like sediment overwash, inlet formation, and island migration that are sensitive to climate-related changes in storminess and the rate of sea-level rise. Data were obtained to understand piping plover habitat distribution and use along the

The collection of borehole geophysical logs and images and continuous water-level data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the GMH Electronics Superfund site near Roxboro, North Carolina, during December 2012 through July 2015. The study purpose was part of a continued effort to assist the U.S. Environmental Protection Agency in the de
