Still images from Voyage Marine Science (2010/11 VMS) to Mertz Glacier Region

The Marine Science voyage (VMS) was conducted on the Aurora Australis between 4 January 2011 and 6 February 2011. The voyage incorporated oceanographic measurements along the CLIVAR SR3 Transect and around the Mertz Glacier region. Underwater still images were collected from 93 sites ranging in depth from 170 m to 2300 m across George V shelf in East Antarctica. The camera equipment was designed and operated by the Australian Antarctic Division (AAD) marine science support team. The camera was attached to either the CTD frame or the beam trawl frame and lowered to 4-5 m from the seafloor and held in position for 2-15 minutes. All still images were stamped with UTC time. Stations were named according to the frame (e.g. CTD or BT), the sequence number of that particular frame (e.g. CTD53), followed by the instrument used (e.g. CAM for camera) and then the deployment number. For example, BT5_CAM16 was the fifth deployment using the beam trawl frame and the sixteenth camera deployment of the survey overall.
