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.

本海洋科学航次（VMS）于2011年1月4日至2011年2月6日期间，在“南极光号”（Aurora Australis）科考船上开展。本次航次涵盖沿CLIVAR SR3断面及默茨冰川（Mertz Glacier）周边海域的海洋学观测工作。研究团队在南极东海岸的乔治五世陆架（George V Shelf）的93个站位采集了水下静态图像，各站位水深范围为170米至2300米。
该摄像设备由澳大利亚南极局（Australian Antarctic Division, AAD）海洋科学支持团队设计并操作。相机被固定于温盐深仪（CTD）架或桁拖网架上，下放至距海底4至5米处，并保持拍摄位置2至15分钟。所有静态图像均带有协调世界时（UTC）时间戳。
站位命名规则如下：以架体类型（如CTD或BT）开头，紧随对应架体的序列号（如CTD53），随后标注所用仪器的标识（如CAM代表相机），最后加上部署序号。例如，BT5_CAM16代表使用桁拖网架开展的第5次部署，亦是本次科考的第16次相机部署作业。
