Baseline Coastal Oblique Aerial Photographs Collected at Breton Island and the Chandeleur Islands, Louisiana, January 22, 2011
The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project, conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise. On January 22, 2011, the USGS's NACCH project conducted an obli
Baseline Coastal Oblique Aerial Photographs Collected Ponte Vedra, Florida, to South Carolina/North Carolina Border, August 24, 2011
The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project conducts baseline and storm-response photography missions to document and understand the changes in the vulnerability of the Nation's coasts to extreme storms and longer-term processes related to sediment supply and sea-level rise.

Fiber-optic distributed temperature data collected along the streambed of the East River, Crested Butte, CO, USA
The data set includes temperature data from the base of the water column along the sediment interface of the East River near Crested Butte, Colorado, USA, in support of ongoing study regarding groundwater/surface water exchange. The data were collected from 08/09/2016 to 08/31/2016 using a fiber-optic distributed temperature sensing system that has 1.01 m spatial resolution along the linear fiber-
New record of California red-legged frogs (Rana draytonii) in Whitewater Canyon, Riverside County, CA, USA
In February 2017, a population of California red-legged frog Rana draytonii was discovered in the southern foothills of the San Bernardino Mountains of Riverside County, California, near the edge of the species historic distribution. A few days after the first sightings of R. draytonii at the Whitewater Preserve, we conducted a visual daytime search for frogs, tadpoles and egg masses followed by a
USGS bathymetric and hydrodynamic survey of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana
The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishm
USGS Measurements of Water Quality in San Francisco Bay (CA), 2016-2021 (ver. 4.0, March 2023)
The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. This U.S.G.S. Data Release is a continuation of the previously published 1969-2015 dataset (Cloern and Schraga, 2016; Schraga and Cloern, 2017), it will archive and make available all measurements from 2016 and thereafter. Each year, a data file containing the previous years data w

Female Faxonius (formerly Orconectes) quadruncus broodstock collected for toxicity testing
Broodstock individual Faxonius quadruncus were collected for culturing eggs until hatch. Hatchling crayfish were used to be used in toxicity testing to assess hazards of metals mixtures to young Faxonius quadruncus
SPV field trials bait uptake data
These data were collected as part of a field trial to test the effectiveness of a sylvatic plague vaccine (see Rocke et al., 2017 for details). Vaccine and control plots were selected randomly from the available pairs at each location. Baits containing Rhodamine B, a biomarker, were distributed at each plot. At least 1 week and no more than 2 months post-baiting each year, local collaborators cap
Analytical inorganic chemistry results for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015
Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the Sediment-Bound Co
Treasure Valley Drains
To begin filling data gaps for development of a Treasure Valley groundwater-flow model, we installed 10 new real-time streamgages on drains along the lower Boise River from Eagle to Parma. The streamgages will monitor the amount of shallow groundwater the aquifer system discharges to surface water. This was a missing component in previously developed models.
A multi-year record of chemical and isotopic composition of water from springs of the Shenandoah National Park, Virginia
From 1994 through 2017, the U.S. Geological Survey in cooperation with the National Park Service, Luray, Virginia Station collected and analyzed samples of selected springs, air and unsaturated-zone gases in Shenandoah National Park, Virginia. These data include field measurements of water temperature, specific conductance, concentrations of dissolved oxygen (O2), and pH. Laboratory measurements i
