BRUVS surveys collected for the Barossa Environmental Baseline Study 2015, Western Australia (ConocoPhillips)

Stereo Baited Remote Underwater Video Stations (BRUVS) were deployed and retrieved across two shoals of regional interest, Evans and Tassie Shoals, two of the closest shoals to the Barossa field. The allocation of deployment positions across each shoal was conducted using a regular/random design within the bounds of the 60 m depth contour whilst maintaining a minimum distance of 250 m between each stereo-BRUVS unit. Once the positions were derived, the sequence of deployments, in sets of eight replicate units, was determined by proximity and prevailing sea conditions on the day. A total of 72 stereo-BRUVS deployments were conducted at Evans Shoal, and 23 deployments at Tassie ShoalThe BRUVS surveys were undertaken by the Australian Institute of Marine Science (AIMS) in collaboration with ConocoPhillips as part of the Barossa field environmental baseline and marine studies program. The surveys were undertaken between 13 September and 1 October 2015, on the RV Solander. They covered five principle locations of regional interest, including Evans, Tassie and Blackwood Shoals, the closest shoals to the Barossa field, as well as two mid-shelf seabed locations adjacent to Goodrich Bank and Cape Helvetius, relevant to a potential gas export pipeline route.

研究团队在两处具有区域研究价值的沙洲——埃文斯沙洲（Evans Shoals）与塔西沙洲（Tassie Shoals）——部署并回收了诱饵式立体远程水下视频站（Stereo Baited Remote Underwater Video Stations，BRUVS），这两处沙洲是距离巴罗萨油田（Barossa field）最近的沙洲之一。各沙洲的布放点位采用规则/随机设计方案，布设范围限定在60米以深的等深线范围内，且每台立体BRUVS设备之间需保持至少250米的间距。点位确定后，每8台重复布设单元为一组的布放顺序，将根据当日海域的点位邻近性与实际海况确定。埃文斯沙洲共计完成72次立体BRUVS布放，塔西沙洲则完成23次布放。本次BRUVS调查由澳大利亚海洋科学研究所（Australian Institute of Marine Science，AIMS）与康菲石油公司（ConocoPhillips）合作开展，作为巴罗萨油田环境基线与海洋研究计划的一部分。调查于2015年9月13日至10月1日期间，在"索兰德号"（RV Solander）科考船上完成。本次调查覆盖了5处具有区域研究价值的核心点位，包括距离巴罗萨油田最近的埃文斯沙洲、塔西沙洲与布莱克伍德沙洲（Blackwood Shoals），以及毗邻古德里奇海台（Goodrich Bank）和赫尔维蒂乌斯角（Cape Helvetius）的两处陆架中部海底点位，上述点位均与潜在的天然气出口管道路由相关。
