Abstract:
Water column profiles were measured at the locations of pockmarks B, D and E, using a Sea & Sun CTD90M multiprobe. The sensors for pressure, temperature, conductivity and optical dissolved oxygen in the multiprobe were manufactured by Sea & Sun Technology GmbH. The turbidity sensor was manufactured by Seapoint Sensors Inc., and the ISM-2001C inductive 2D current meter with compass by HS Engineers GmbH.
