Newsweek looks at efforts by a group of scientists and mariners to map most of the ocean floor by the year 2030. The objective was endorsed by a meeting of GEBCO, the General Bathymetric Chart of the Oceans, last June. The scale of the project is vast:
To date, more than 85 percent of the seafloor has not been mapped using modern methods. Since 70 percent of the Earth is covered in oceans, this means that we quite literally don’t know our own planet. “We know the surface of Mars better than we do the seafloor,” says Martin Jakobsson, a researcher at Stockholm University.

New seafloor maps of the Monterey Bay area have been released as part of the California Seafloor Mapping Program. The maps “reveal the diverse and complex range of seafloor habitats along 130 kilometers (80 miles) of the central California coast from the Monterey Peninsula north to Pigeon Point.” [Leventhal Map Center]

The USGS‘s California Seafloor Mapping Program has produced a set of insanely detailed maps of the sea floor along the California coast. Downloadable as rather hefty PDF files; the map sheets are three feet across as paper maps. Above, a detail from the shaded-relief bathymetry map of the San Francisco area. Boing Boing, Wired.
