Faceing Blog's First images of 'Titanic of the Golden Gate' revealed

The sonar images of the SS City of Rio de Janeiro are part of the National Oceanic Atmospheric Administration's two-year study to map shipwrecks in the Golden Gate National Recreation Area and Gulf of the Farallones National Marine Sanctuary.

The SS City of Rio de Janeiro, which transported passengers and cargo between Asia and San Francisco, has been found in 287 feet of water in the San Francisco Bay. The ship sank in 1901 after running into jagged rocks near where the Golden Gate Bridge now stands. The ship is shown here in an 1894 photo taken in Nagasaki, Japan.

The SS City of Rio de Janeiro shipwreck is just one of a number of shipwrecks in the San Francisco Bay Area. It's shown here in a multi-beam sonar image of San Francisco's Golden Gate area along with the SS City of Chester and MV Fernstream.

This present day photo at the entrance of the Golden Gate shows Fort Point at the far right where the SS City of Rio de Janeiro struck rocks in a thick fog and sank on February 22, 1901.

The SS City of Rio de Janeiro shipwreck was mapped using Coda Octopus's three-dimensional Echoscope sonar, which produced this profile view of the shipwreck.
