Daily Science Report: Friday February 3rd

By Mike Cheadle
Sentry was recovered at lunchtime and another superb Sentry map showed exactly where the outcrops were, but alas, none at the deepest depths. We carried out a brief ship multibeam and magnetometer survey to get us to the launch site for Jason and we sent off Jason to search for gabbros at the base of the sheeted dike outcrops, which are clearly visible on the two previous Sentry maps and ground-truthed by dives from the 2005 Atlantis cruise led by Jeff Karson. We completed processing the rocks from the previous Jason dive & interestingly the sampling suggests an abrupt gabbro dike transition.
