Eric Moore, Wayne Baldwin, and Tommy O’Brien are deploying multichannel seismic streamer onboard R/V Pelican during a 2013 seismic cruise in the Gulf of Mexico as part of the gas hydrates program. 

Some areas that would be inundated (in red) during the SAFRR tsunami scenario. Top, in Oakland and Alameda, in the eastern San Francisco Bay area, large parts of the Oakland Airport would be flooded.

Maximum current speeds for the Port of Los Angeles (POLA) and the Port of Long Beach (POLB) generated during the SAFRR tsunami scenario. The ports are protected by a breakwater, but during the tsunami there would be dangerously fast currents around the port entrances in the wall, locally referred to as “Angels Gate” (at POLA) and “Queens Gate” (at POLB).

A bright orange Brisingid starfish is seen in the center of the image. The background is a thicket of live (white) and dead (brown) Lophelia coral. Several squat lobsters (Eumunida picta) can be seen in the coral, as well as a blue encrusting sponge and an urchin (foreground, lower left).

Hundreds of catsharks, or chainlink dogfish, rest on one of the "Billy Mitchell" Fleet shipwrecks. The shipwreck has also been occupied by colonies of anemones, starfish, and hydroids.
