San Francisco Bay Multi-beam Bathymetry: Area A

Data provided by  National Oceanic and Atmospheric Administration

These multi-beam bathymetric data were collected over shallow subtidal areas in the San Francisco Bay estuary system. Bathymetric and acoustic backscatter data were collected simultaneously in 84 survey blocks. Seventy five of these blocks were surveyed with 100% cover of backscatter imagery and nine blocks were surveyed with 50% backscatter coverage. These data were collected as source material for planned benthic habitat mapping. An earlier project had been completed to map the very-shallow subtidal and intertidal areas.

San Francisco Bay Interferometric Bathymetry: Area A

Data provided by  National Oceanic and Atmospheric Administration

These interferometric bathymetric data were collected with the Edgetech 6205 sonar system in the San Francisco Bay. Bathymetric and acoustic backscatter data were collected simultaneously in 84 survey blocks. Seventy five of these blocks were surveyed with 100% cover of backscatter imagery and nine blocks were surveyed with 50% backscatter coverage. These data were collected as source material for planned benthic habitat mapping. An earlier project had been completed to map the very-shallow subtidal and intertidal areas using optical methods.

San Francisco Bay Interferometric Bathymetry: Area B

Data provided by  National Oceanic and Atmospheric Administration

High resolution sonar data were collected over ultra-shallow areas of the San Francisco Bay estuary system. Bathymetric and acoustic backscatter data were collected simultaneously in 10 survey blocks. All of these blocks were surveyed with 100% cover of backscatter imagery. These data were collected as source material for planned benthic habitat mapping. An earlier project had been completed to map the very-shallow subtidal and intertidal areas using optical methods.

Delaware Bay, Delaware Benthic Grabs 2007

Data provided by  National Oceanic and Atmospheric Administration

The Coastal Program of Delaware's Division of Soil and Water conservation (DNREC), the University of Delaware, Partnership for the Delaware Estuary, and the New Jersey Department of Environmental Protection have partnered and are carrying out a bottom and sub-bottom imaging project to identify and map the benthic habitat and sub-bottom sediments of Delaware Bay and River. This project was initiated to better understand the distribution of bottom sediment types, habitat biodiversity, and most importantly, human's impact on the bay bottom and its living resources.
