Sentry comes out of water to charge its batteries in preparation for a follow-on mission to map Gary's Bad Hang, a potential site for a primary node on the cabled observatory.

During this cruise, both Jason and Sentry worked at Southern Hydrate Ridge. During Jason dive 508, Sentry was recovered while Jason continued to work.
