Vacuuming out Broadband Caisson
The ROV ROPOS vacuums out sediment in a caisson at the summit of Southern Hydrate Ridge. In 2014, a broadband seismometer will be placed in the caisson and covered in silica beads to optimize acquisition of acoustic signals by lowering ocean "noise" (e.g. currents). Credit: UW/NSF-OOI/CSSF.
