Objectives | The purpose of this mini-cruise on the RRS James Clark Ross was to deploy two moorings and take box cores in support of two AFI funded research projects working in Marguerite Bay. In a 36 hour period 2 moorings were deployed: one 22 miles from Rothera in 841m of water, the other in Ryder Bay 2 miles from Rothera in 503m of water. The moorings will stay in place until next season when they will be recovered and then re-deployed in the same location. In support of these instruments 4 box cores and 2 CTDs were taken. | ||||||||||||||||||||||||||||||||||||
