California State Waters Map Series: Offshore of Carpinteria, California California State Waters Map Series: Offshore of Carpinteria, California
In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the 3-nautical-mile limit of California’s State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration...
Marine benthic habitat mapping of the West Arm, Glacier Bay National Park and Preserve, Alaska Marine benthic habitat mapping of the West Arm, Glacier Bay National Park and Preserve, Alaska
Seafloor geology and potential benthic habitats were mapped in West Arm, Glacier Bay National Park and Preserve, Alaska, using multibeam sonar, groundtruthed observations, and geological interpretations. The West Arm of Glacier Bay is a recently deglaciated fjord system under the influence of glacial and paraglacial marine processes. High glacially derived sediment and meltwater fluxes...

Onshore and offshore geologic map of the Coal Oil Point area, southern California Onshore and offshore geologic map of the Coal Oil Point area, southern California
Geologic maps that span the shoreline and include both onshore and offshore areas are potentially valuable tools that can lead to a more in depth understanding of coastal environments. Such maps can contribute to the understanding of shoreline change, geologic hazards, both offshore and along-shore sediment and pollutant transport. They are also useful in assessing geologic and biologic...
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 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 sediment and meltwater fluxes, slope...
Sidescan Sonar Imagery of the Escanaba Trough, Southern Gorda Ridge, Offshore Northern California Sidescan Sonar Imagery of the Escanaba Trough, Southern Gorda Ridge, Offshore Northern California
This map features sidescan imagery of the northern Escanaba (NESCA) site at the Escanaba Trough, southern Gorda Ridge, offshore northern California. The Escanaba Trough, a largely sediment-covered seafloor spreading center, contains at least six large massive sulfide deposits. It is a slow spreading center (2.5 cm/yr) with axial depths locally exceeding 3,300 m. Discrete igneous centers...
Views of the Sea Floor in Northern Monterey Bay, California Views of the Sea Floor in Northern Monterey Bay, California
A sonar survey that produced unprecedented high-resolution images of the sea floor in northern Monterey Bay was conducted in 2005 and 2006. The survey, performed over 14 days by the U.S. Geological Survey (USGS), consisted of 172 tracklines and over 300 million soundings and covered an area of 12.2 km2 (4.7 mi2). The goals of this survey were to collect high-resolution bathymetry (depth...
High-resolution bathymetry and topography of south San Francisco Bay, California High-resolution bathymetry and topography of south San Francisco Bay, California
This map consists of a view of the southern end of San Francisco bay with the water 'removed.' The image is overlain by a set of six figures: - Figure 1. Perspective view looking southeast down south San Francisco Bay. - Figure 2. Perspective view looking east with the Diablo Range in the distance. - Figure 3. Perspective view looking southwest over Bair Island toward Redwood City. -...
Sand waves at the mouth of San Francisco Bay, California Sand waves at the mouth of San Francisco Bay, California
A multibeam bathymetric survey that produced unprecedented high resolution images of the mouth of San Francisco Bay was conducted in 2004 and 2005. The survey, performed over forty-four days by the Seafloor Mapping Lab at California State University, Monterey Bay, consisted of 1,138 track lines, 1.1 billion soundings, and covered an area of 154 km2 (60 mi2). The goals of this survey were...
Under the Golden Gate Bridge — Views of the sea floor near the entrance to San Francisco Bay, California Under the Golden Gate Bridge — Views of the sea floor near the entrance to San Francisco Bay, California
San Francisco Bay in Northern California is one of the largest and most altered estuaries within the United States. The sea floor within the bay as well as at its entrance is constantly changing due to strong tidal currents, aggregate mining, dredge disposal, and the creation of new land using artificial fill. Understanding this dynamic sea floor is critical for addressing local...
