Marine benthic habitat mapping of Muir Inlet, Glacier Bay National Park and Preserve, Alaska, with an evaluation of the Coastal and Marine Ecological Classification Standard III
Seafloor geology and potential benthic habitats were mapped in Muir Inlet, Glacier Bay National Park and Preserve, Alaska, using multibeam sonar, ground-truth information, and geological interpretations. Muir Inlet is a recently deglaciated fjord that is under the influence of glacial and paraglacial marine processes. High glacially derived...

Sea-Floor Mapping and Benthic Habitat GIS for the Elwha River Delta Nearshore, Washington
From March 1531, 2005, more than 252 km (19.5 km2) of seafloor offshore of the Elwha River Delta in the central Strait of Juan de Fuca was mapped by the USGS Coastal and Marine Geology Program. The purpose of this nearshore mapping was to (1) obtain high resolution bathymetry and acoustic reflectance properties of the seabed, (2) examine and...

Seafloor mapping and benthic habitat GIS for southern California, volume III
From August 8-27, 2005, more than 75 km of the continental shelf (Fig. 1) in water depths of 20-70m southeast of Santa Barbara, were surveyed during the USGS cruise S-1-05-SC (http://walrus.wr.usgs.gov/infobank/s/s105sc/html/s-1-05-sc.meta.html). Both Interferometric sonar and 14 hours of both vertical and oblique georeferenced submarine digital...

Survey report of NOAA Ship McArthur II cruises AR-04-04, AR-05-05 and AR-06-03: habitat classification of side scan sonar imagery in support of deep-sea coral/sponge explorations at the Olympic Coast National Marine Sanctuary
Habitat mapping and characterization has been defined as a high-priority management issue for the Olympic Coast National Marine Sanctuary (OCNMS), especially for poorly known deep-sea habitats that may be sensitive to anthropogenic disturbance. As a result, a team of scientists from OCNMS, National Centers for Coastal Ocean Science (NCCOS), and...
Intelmann, Steven S.; Cochrane, Guy R.; Bowlby, C. Edward; Brancato, Mary Sue; Hyland, Jeffrey Geologic characteristics of benthic habitats in Glacier Bay, southeast Alaska
In April 2004, more than 40 hours of georeferenced submarine digital video was collected in water depths of 15-370 m in Glacier Bay to (1) ground-truth existing geophysical data (bathymetry and acoustic reflectance), (2) examine and record geologic characteristics of the sea floor, and (3) investigate the relation between substrate types and...

Nearshore benthic habitat GIS for the Channel Islands National Sanctuary and southern California State Fisheries Reserves. Volume 1
The nearshore benthic habitat of the Santa Barbara coast and Channel Islands supports diverse marine life that is commercially, recreationally, and intrinsically valuable. Some of these resources are known to be endangered including a variety of rockfish and the white abalone. Agencies of the state of California and the United States have been...
Cochrane, Guy R.; Nasby, Nicole M.; Reid, Jane A.; Waltenberger, Ben; Lee, Kristen M. Mapping the seabed and habitats in National Marine Sanctuaries - Examples from the East, Gulf and West Coasts
The National Marine Sanctuary System requires seabed and habitat maps to serve as a basis for managing sanctuary resources and for conducting research. NOAA, the agency that manages the sanctuaries, and the USGS have conducted mapping projects in three sanctuaries (Stellwagen Bank NMS, Flower Garden Banks NMS, and Channel Islands NMS) with an...
Valentine, Page C.; Cochrane, Guy R.; Scanlon, Kathryn M. Use of acoustic classification of sidescan sonar data for mapping benthic habitat in the Northern Channel Islands, California
Highly reflective seafloor features imaged by sidescan sonar in nearshore waters off the Northern Channel Islands (California, USA) have been observed in subsequent submersible dives to be areas of thin sand covering bedrock. Adjacent areas of rocky seafloor, suitable as habitat for endangered species of abalone and rockfish, and encrusting...
Cochrane, Guy R.; Lafferty, Kevin D. Activities and preliminary results of nearshore benthic habitat mapping in southern California, 1998
The nearshore benthic habitat of the Santa Barbara coast and Channel Islands supports a diversity of marine life that are commercially, recreationally, and intrinsically valuable. Some of these resources are known to be endangered including a variety of rockfish and the White Abalone. State and National agencies have been mandated to preserve and...

Physical characteristics of dungeness crab and halibut habitats in Whidbey Passage, Alaska
In Glacier Bay National Park, Alaska there are ongoing studies of Dungeness Crab (Cancer magister) and Pacific Halibut (Hippoglosus stenolepis). Scientists of the United States Geological Survey (USGS) are attempting to ascertain life history, distribution, and abundance, and to determine the effects of commercial fishing in the park (Carlson et...
