ROV Dive S0465 - JaichMaa ’ja’ag Vent Field

The JaichMaa ’ja’ag Vent Field consists of four large and several small hydrothermal edifices aligned north-south-ish and spanning a 400 m distance. The large edifices are up to 50 m across and 22 m high. The primary objective of this dive is to continue collecting heat flow data using the heat flow probe on transects across the vent field. A secondary goal is to collect push cores of sediment near and far from the vents. The on-bottom location is 550 m to the west of the northern pair of edifices. This location is on an AUV subbottom profile track, and the dive will begin with a heat flow transect working towards the vents along the subbottom track.
