![]() The USGS is a key partner in the California Seafloor Mapping Program: a large, unique, and historically ambitious collaboration between State and Federal agencies, academia, and the private sector to create a comprehensive base-map series for all of California’s ocean waters. “Each organization brings to the table a unique and complementary set of resources, skills, and know-how.” By working with other government agencies, universities, and private industry, the USGS could fully leverage all its resources,” said USGS Pacific Region Director Mark Sogge. “A program of this vast scope can’t be accomplished by any one organization. Geological Survey-a map set for the area offshore of Carpinteria (about 120 kilometers northwest of Los Angeles), a catalog of data layers for geographic information systems, and a collection of videos and photos of the seafloor in State waters along the entire California coast, Three new products in an ongoing series were released on August 9, 2013, by the U.S. New imagery, specialized undersea maps, and a wealth of data from along the California coast are now available. Science and technology have peeled back a veil of water just offshore of California, revealing the hidden seafloor in unprecedented detail. (Dots are easier to see in online images.) High-resolution versions of the photographs can be viewed by clicking “View original” below photograph window. Two green dots in the video window (from lasers mounted on the camera and used as reference points) are 15 centimeters (6 inches) apart likewise the red dots in both windows. This example-sand ripples at a depth of approximately 15 meters (49 feet)-is from a trackline just offshore of Half Moon Bay, California. (At scales shown here, red dots are too closely spaced to distinguish.) Clicking on a trackline starts video in the lower-left window and associated photographs in the lower-right window. Interactive map (here with added labels) allows viewers to zoom into areas of interest video tracklines appear in purple and photograph locations (dots) in red.
