All Data

Two unique datasets were gathered to document whether flow management for hydropower affects the abundance and diversity of aquatic insect assemblages. The first dataset was collected in Grand Canyon from 2012-2014 by citizen scientists rafting the Colorado River. Simple light traps were set out each night in camp and used to capture the adult life stages of aquatic insects that emerged from the C

Lidar-derived bare-earth topography Digital Elevation Model (DEM) mosaic and classified point-cloud datasets were produced from remotely sensed, geographically referenced elevation measurements collected post-Hurricane Joaquin on November 26, 2015.

Water surface elevation measurements were collected in the spring of 2015 along the upper Willamette River, Oregon, from Eugene to Corvallis. These surveys were collected using an RTK-GPS on a motorboat traveling on-plane down the river. These data sets were collected for equipment calibration and validation for the NASA AirSWOT mission, but serve as potential data sets for future studies on the u

These data files include georeferenced water-quality data with associated time stamps (Central Standard Time) for basic water-quality parameters as measured by a towed multiparameter sonde (YSI 6920 sonde) from a manned boat in the Chicago Sanitary and Ship Canal. Data were collected on February 25-27, 2010, and again on March 2-3, 2010. The data collected in February 2010 had the sonde on a fixed

Water velocities were measured in the Chicago Sanitary and Ship Canal (CSSC) in 2010 and 2011 using Teledyne Rio Grande 600 kHz and 1200 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. Data were processed using the Velocity Mapping Toolbox (Parsons et al., 2013). Any data assigned a value of "-9999" are bad or missi

These data provide the locational coordinates, soil texture characteristics, plant species occurrence and cover, and vegetation summary characteristics for the Tsezhin bii region in the south-central area of the Navajo Nation in Arizona. They were collected in the fall of 2004 and their subsequent analysis reported in the paper titled 'Vegetation of semi-stable rangeland dunes of the Navajo Nation

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Canyonlands and Upper Neches River Corridor Units of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 11,

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Menard Creek Corridor Unit of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 21 and 22, 2014, in coopera

In August 2015, water velocities around a fully-loaded commercial barge tow were measured as the barge tow traveled upstream through the Chicago Sanitary and Ship Canal from a starting position in Lockport Pool, and passed through the Electric Dispersal Barrier System at river mile (RM) 296 near Romeoville, IL. Velocity measurements were made in and alongside the gap formed by the junction between

On May 25, 2014, a rain-on-snow induced rock avalanche occurred in the West Salt Creek Valley on the northern flank of Grand Mesa in western Colorado. The avalanche traveled 4.6 km down the confined valley, killing 3 people. The avalanche was rare for the contiguous U.S. because of its large size (54.5 Mm3) and long travel distance. To understand the avalanche failure sequence, mechanisms, and mob

These data sets contain information on the probabilities of hurricane-induced erosion (collision, inundation and overwash) for each 1-km section of the Gulf of Mexico coast for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the direct l

These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide pre- and post-calibration lidar-derived submerged topography for a portion of the submerged environs of Fort Lauderdale, Florida. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on April 21 and 22, 2014. The data were
