Southeast Tasmania Temperate Reef Survey: Post-Survey Report

This report provides a description of the research activities completed during the CERF Marine Biodiversity Hub survey of southeast Tasmanian temperate reefs, aboard RV Challenger, as part of the Hub's Surrogates Program. The survey was undertaken as a collaborative exercise between the Tasmania Aquaculture and Fisheries Institute (TAFI, University of Tasmania) and Geoscience Australia (GA), and was completed in two stages during 2008 and 2009.

This report describes the methods employed in the mapping and video characterisation of shallow-shelf temperate reef habitats across seven survey sites in southeast Tasmania. Preliminary results are provided of the analysis of multibeam sonar and underwater video data. Examples of the types of biota encountered in the towed video and stills photography, and initial interpretations of the benthic communities are also provided. In addition, initial results are presented from the deployment of an Autonomous Underwater Vehicle (AUV) to collect high resolution photographs of reefs and associated biota.

本报告详述了“挑战者号”科考船（RV Challenger）执行塔斯马尼亚东南部温带礁体调查期间完成的各项研究工作，该调查为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）替代物项目（Surrogates Program）的组成部分。本次调查由塔斯马尼亚水产与渔业研究所（TAFI，塔斯马尼亚大学）与澳大利亚地质调查局（Geoscience Australia, GA）联合开展，于2008年与2009年分两阶段完成。本报告详述了塔斯马尼亚东南部7个调查站位的浅海温带礁体栖息地制图与视频表征所采用的方法，提供了多波束声呐与水下视频数据分析的初步结果。同时，本报告展示了拖曳式视频与静态摄影中记录到的各类生物样本，以及底栖群落的初步解析结果。此外，本报告还呈现了自主水下航行器（Autonomous Underwater Vehicle, AUV）采集礁体及其伴生生物的高分辨率照片所得到的初步成果。
