April 27: Studying Geology Underwater: Landslides, Tsunamis, and Earthquakes

Diving on steep slopes means that commonly we see evidence of slope instability in the form of landslides and/or the bare rock faces, called headwall scarps, left behind after the landslide has occurred. We found spectacular examples of both these features during our dives.

April 19: Okeanos Explorer Data Management Download

An expedition can generate about a dozen terabytes of information. And all of this data has to go through our system on the ship, formatting and organizing everything so that it can be used easily by scientists on shore, as they work with the shipboard scientists to plan and direct ROV dives.

The first ideas for the Océano Profundo 2015 expedition trace their roots back to 2011, when the NOAA Office of Ocean Exploration and Research, in partnership with the Institute for Exploration, hosted a workshop on Systematic Telepresence-Enabled Exploration in the Atlantic Basin.
