View some of the spectacular underwater footage captured by the Little Hercules remotely operated vehicle (ROV) on July 6, 2010, during the Indonesia-USA Deep-Sea Exploration of the Sangihe Talaud Region expedition on NOAA Ship Okeanos Explorer.

The crew launched the ROV for the dive at 5º 14.964'N 126º 39.378'E around 0815. The dive began 150 meters below the summit on the eastern slope of a steep ridge. The top of the ridge was at a depth of approximately 1,050 meters. 

The pilots traversed the ROV up a steep face of rock that was lightly covered in fine-grained pelagic sediment and contained several different species of corals, sponges, and crinoids. The team captured excellent close ups of what may turn out to be a number of completely new species for scientists. Biomass appeared to increase as the ROV approached the summit ridge and was mostly dominated by sessile species. Scientists also happened to spot an octopus hiding beneath a pile of rocks. 

As the ROV traveled in a southerly direction down the ridge, scientists found an area with relatively few organisms that appeared to have been recently disturbed. They did not find any evidence of hydrothermal or volcanic activity at this site.
