IMOS - AUV SIRIUS CAMPAIGN: TASMANIA, JUNE 2011

Tasmania – Tasman Peninsula, Freycinet MPA and Governor’s Island (Barrett, Johnson):Dives in Tasmania were focused on two main goals. One aspect of the surveys in Tasmania is to look at deepwater benthic assemblages associated with rocky reefs. These dives featured broad grids over the dive sites and a pair of dense overlapping grids. Around the Tasman peninsula, dives were completed in shallower water and featured a pair of dense grids connected by reciprocal legs. Two sites near the Nuggets and in the Freycinet MPA were revisited from previous trips in 2008 and 2009. These were broad grids and did not feature any dense grids making direct comparison difficult.

塔斯马尼亚——塔斯曼半岛、菲瑟涅海洋保护区（Freycinet MPA）与总督岛（Barrett、Johnson）：塔斯马尼亚海域的潜水作业聚焦两大核心目标。本次调查的一项核心内容为研究与岩礁相关联的深水底栖生物群落。此类潜水作业在各潜水点位布设了大范围网格与一对高密度重叠网格。在塔斯曼半岛周边，潜水作业于浅水区开展，采用了由往返航段连接的一对高密度网格。研究团队还对2008年与2009年考察过的纳格茨（Nuggets）附近两处点位以及菲瑟涅海洋保护区（Freycinet MPA）进行了重访，这些点位仅布设了大范围网格，未设置高密度网格，这使得直接开展数据对比存在难度。
