Cape Canaveral, Florida 2010 Single-beam Bathymetry Data
Single-beam bathymetric surveys were conducted on July 27-29, 2010 along 37 cross-shore transects offshore from Cape Canaveral, Fla. The transects were spaced 500 m apart in the alongshore direction and each was approximately 5 km long in the cross-shore.
Laysan Teal Duck Microsatellite Data; Laysan Island 1999-2009, Midway Island 2007-2010
Determine genetic diversity and quantify variation in the endangered Laysan Teal Duck (Anas laysanensis) at microsatellite loci sampled from 230 individuals at Laysan Island (1999-2009) and Midway Island (2007-2010).
Historical methyl mercury in San Francisco Bay
San Francisco Bay, California is considered a mercury-impaired watershed. Elevated concentrations of mercury are found in water and sediment as well as fish and estuarine birds. Sources of mercury to the watershed since 1845 include sediment-associated mercury from mercury mining, mercury losses from gold amalgamation activities in mines of the Sierra Nevada, aerial deposition of mercury from gl
High-resolution geophysical data collected along the Delmarva Peninsula 2014, USGS Field Activity 2014-002-FA
The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy. A USGS cruise was conducted in the summer of 2014 to map the inner-continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescal
High-resolution geophysical data collected offshore of Fire Island, New York in 2011, U.S. Geological Survey Field Activity 2011-005-FA
The U.S. Geological Survey (USGS) mapped approximately 336 square kilometers of the lower shoreface and inner-continental shelf offshore of Fire Island, New York in 2011 using interferometric sonar and high-resolution chirp seismic-reflection systems. These spatial data support research on the Quaternary evolution of the Fire Island coastal system and provide baseline information for research on c
Riparian vegetation, Colorado River, and climate: five decades of spatio-temporal dynamics in the Grand Canyon with river regulation
These data include image-based classifications of total vegetation from 1965, 1973, 1984, 1992, 2002, 2004, 2005, and 2009, and characteristics of the river channel along the riparian area of the Colorado River between Glen Canyon Dam and Lake Mead Reservoir. Also, these polygon data represent the area inundated by the Colorado River in the aerial imagery from overflight of the Grand Canyon in May

California State Waters Map Series--Offshore of Aptos, California
This publication about the Offshore of Aptos map area includes 10 map sheets that contain explanatory text, in addition to this descriptive pamphlet and a data catalog of geographic information system (GIS) files. A temporary DOI# was issued when the publication was in the works. Once it became an official USGS Open-File Report it was given a formal DOI#, which this temporary DOI# redirects to.

Flow management and fish density regulate salmonid recruitment and adult size in tailwaters across western North AmericaData
This data is a compilation of fishery monitoring data collected by state agencies over several decades in tailwaters downriver of dams in Colorado, Utah, Montana, Wyoming, Idaho, New Mexico, Arizona, California, and Oregon. Specifically, the data contained herein is summary data used in four generalized linear mixed models that were developed to assess the biological and hydrologic factors that in
Evaluating rehabilitation efforts following the Milford Flat Fire: Successes, failures, and controlling factorsData
Uncontrolled wildfire in arid and semiarid ecosystems has become an increasing concern in recent decades. Active rehabilitation of fire-affected areas is often quickly initiated to minimize long-term ecosystem damage. However, the complex soil-geomorphic-vegetation patterns and low and variable moisture conditions in these regions makes restoration challenging. To further inform these post-fire ma
