50 kt wind gusts and 20 ft seas meant that it’s been a “rock & rollin” day at sea. Fortunately sliding chairs were the worst that happened to us. We recovered last nites dredge in the early morning and found we had collected diabase. Since have been multi beaming, with the triumph of the day being, that we found our 4th oceanic core complex! We really are in a reduced magma segment of the Southwest Indian Ridge, with nearly all the major bathymetric features being oceanic core complexes or the large 1 km high ridges typical of failed oceanic core complexes. Our next dredge is planned for 4 am this morning. I’m sticking with gabbro. Wish us luck!
Our location earlier today (red star). We’ve completed all of the multi beam lines to the west of the “star” and the horizontal ship tracks show where we went dredging. The “topography” is from satellite derived gravity.
