Two had 5-6 inches of mud with water overlaying. Extensive scrolling problems with winch. JC094-STN048 ROV236 Remote operated vehicle ROV 2013-11-18T19:12:00 14.89133 -48.15000 -867 Came up slope from 850m across sediments and fossil corals. Latter part of upward traverse smooth brown rock with brittle stars. Top of seamount the same. Wind picks up to >35kts so ship asks us to stop moving. After waiting to recover, continue to top of plateau. Move to deeper side of seamount and traverse towards top again. JC094-STN049 ROV237 Remote operated vehicle ROV 2013-11-20T23:15:00 14.85000 -48.26650 -2181 Start sediment plain, then move up basalt steep slopes. Sponges and sediment in crevices. Few corals. Much the same up to the top. Strong current on top of ridge, so need to lift up and move east. Strong currents prevent sampling at top. JC094-STN055 ROV238 Remote operated vehicle ROV 2013-11-22T00:29:00 14.89050 -48.15110 Dive 238 JC094-STN053 Box corer BC 2013-11-22T13:39:00 14.76650 -48.25083 -3722 Pull-out: 3.92 tons. Approx 16cm of sediment. Subsampled with piston core liners for storage and with megacore tubes for sampling 1 cm slices (first 2 cores) and 2cm slices (last core). Two subcores for plastics study. Independent S-numbers for each tube and the whole box core. Bulk samples stored in bags. JC094-STN056 ROV239 Remote operated vehicle ROV 2013-11-24T17:01:00 15.42200 -51.08633 -1564 Started out on small knoll North of seamount. Extensive fields of fossil corals. Carried on up ridge, but fossils less abundant with increasing height. Towards top smooth rock with crinoids. Did not quite reach summit. USBL crash due to over heating. JC094-STN058 ROV240 Remote operated vehicle ROV 2013-11-25T22:36:00 15.44833 -51.09150 -2157 Deep parts were rocks/boulders and sediment. Lots of USBL issures, resolved by changing settings in software. At 0800 GMT traverse to start of Dive 239 and scoop up nets of fossil corals.
