The Hawaii-2 Cable Seafloor Observatory (H2O) was established in 1998 at 27° 53'  N, 142° 00' W at ~5000-m depth.  This location, approximately halfway between Hawaii and California, was chosen initially for real-time data acquisition as part of the global seismic network (click to learn more about geophysical research at H2O).  Due to the remote location, underlying the oligotrophic North Pacific Subtropical Gyre, H2O also serves as a model study site for examining deep-sea biodiversity and hypotheses related to food limitation in the deep sea.  In this website, we present all morphotypes of megafauna observed at H2O during cruises in 1998, 1999, 2003, and 2004.  Observations were made with ROVs Jason and JasonII and a camera sled, and several species of fauna were collected by ROV or with an otter trawl.
