Creed. The objective of the multiple echosounder surveys was to map the bathymetry and surficial sediments over time as dredged material was placed in the HARS to remediate contaminated sediments. Maps derived from the multibeam surveys show sea-floor bathymetry, shaded-relief bathymetry, and backscatter intensity (a measure of sea-floor texture and roughness) at a spatial resolution of 3 meters.

Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...

The Santa Barbara channel is a well-known biogeographic transition zone and nearshore rocky reefs and kelp forests are home to many important commercial and recreationally fished species. In particular, rockfishes (genus Sebastes) are long-lived, piscivorous reef fishes that are important predators and are both commercially and recreationally fished. Kelp bass (Paralabrax clathratus), another important fish predator makes up a major sport fishery in southern CA. Finally, CA sheephead (Semicossyphus pulcher) are predators on grazing urchins and have been shown to exert top down control on kelp forests in the area (Hamilton and...

High-resolution geophysical mapping of Lake Powell in the Glen Canyon National Recreation Area in Utah and Arizona was conducted between October 8 and November 15, 2017, as part of a collaborative effort between the U.S. Geological Survey and the Bureau of Reclamation to provide high-quality data needed to reassess the area-capacity tables for the Lake Powell reservoir. Seismic data collected during this survey can help to define the rates of deposition within the San Juan and Colorado Rivers, which are the main inflows to Lake Powell.
