Vacuuming out Broadband Caisson

Vacuuming out Broadband Caisson

The ROV ROPOS vacuums out the 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 aquisition of acoustic signals by lowering ocean "noise" (e.g. currents).
