For
this study, we used remotely operated vehicles (ROV's) to produce
continuous video footage, quantitative video samples, and still
photos of benthic megafauna on. We also used photoquadrat
analysis to document bottom habitat types (based on physical and
biological features of the seafloor), allowing us to develop a
benthic classification system to be used in future studies.
Our vessels were equipped with either a Phantom DS4 ROV
(for depths to 450 m), or the Remora, an ROV designed for deeper
depths. More than 150 hours of digital video tape and thousands
of still photos were made during these surveys.
