Project Title: PICSI Project 7: Submersible/ROV surveys on the Geologist Seamounts to identify ecosystem conditions for deep sea corals and sponges
Project Summary

The Geologist Seamounts are a ring of ancient volcanoes, estimated to be approximately 80 million years old, within 100 miles southwest of the Big Island of Hawaii. Only three of the 12 major seamounts comprising this ring have ever been visited, two of which by only single, relatively short submersible dives back in 1996. We predict that dense communities of corals and sponges will be found on some of these seamounts, but not on others, and the reason is due to differences in their shapes and orientations relative to the direction of the M2 tide.  We propose to explore for the first time ever three ridge-type seamounts, Swordfish, Ellis, and McCall, during 3 separate cruises in years 2015-2017.

Project Title: PICSI Project 7: Submersible/ROV surveys on the Geologist Seamounts to identify ecosystem conditions for deep sea corals and sponges
Methods/Approach

Each year we will conduct four days of ROV surveys to explore one of the Geologist Seamounts: Swordfish, Ellis, and McCall. Analysis of the video data obtained will potentially yield insights on the relationship between topography, current velocity and direction, and deep water coral and sponge communities.
