Southern Surveyor Voyage SS 11/2006 - Video Survey and monitoring for SE MPA's including the Tasmanian Seamounts Marine Reserve

The scientific objectives for the survey were split across two voyages (SS11/2006 for leg 1 and SS02/2007 for leg 2). They were to: * use advanced sampling tools and techniques that are, to the extent possible, non destructive * collect precisely georeferenced baseline data at scientific reference sites to enable indicators to be quantified (e.g. biodiversity metrics and levels of fishing effort at each site). These data will be documented and available for use for targeted monitoring during subsequent surveys * provide results that can assess the achievement of the TSMR management plan to date (revisit four seamounts photographed in 1997 - Main Pedra, Sister 1, K1 and D1; look for changes in fished and unfished sites) and refine baseline data * enable future assessment against performance objectives for the TSMR and selected proposed Commonwealth MPAs - Huon, Tasman Fracture and possibly South Tasman Rise and Freycinet depending on the time available at sea * test efficiency of the various biodiversity metrics to determine effectiveness, cost and potential for monitoring other deepwater reserves * provide samples for key taxa that can be used in subsequent genetic research to refine definition and extent of endemicity in deepwater fauna * complete swath mapping of relevant parts of continental slope between Hobart and SW Cape
This metadata record refers to the acoustic swath and the video data collected during the first of the two surveys. The image annotations collected for this project have been added to the Oracle data base BHIMAGE and the associated videos and still images have been archived as described in MarLIN record 14436 'Benthic Habitats Video Image Archive'.

本次科考的科学目标分为两个航次完成（第一航次为SS11/2006，第二航次为SS02/2007），具体如下：
1. 尽可能采用非破坏性的先进采样工具与技术；
2. 在科学参考站点采集精确地理参考的基线数据，以量化各类指标（例如各站点的生物多样性参数与捕捞努力量水平）。此类数据将被规范记录并开放共享，可供后续科考开展针对性监测时使用；
3. 提供可用于评估迄今塔斯马尼亚海洋保护区（TSMR）管理计划落实情况的成果：重访1997年已拍摄的4座海山（主佩德拉海山、姊妹1号海山、K1海山与D1海山），排查捕捞与非捕捞站点的生境变化，并完善基线数据；
4. 助力未来针对塔斯马尼亚海洋保护区及拟议的联邦海洋保护区（涵盖Huon、塔斯曼断裂带，若海上作业时间允许还可纳入南塔斯曼海隆与弗雷西内特区域）的绩效目标开展评估；
5. 测试各类生物多样性参数的测算效率，以明确其在监测其他深水保护区时的有效性、实施成本与应用潜力；
6. 采集关键类群的样本，用于后续遗传学研究，以厘清深水动物区系的特有性定义与分布范围；
7. 完成霍巴特至西南角之间大陆坡相关区域的全覆盖条带测绘。

本元数据记录对应两次科考中的第一次航次所采集的声学条带测绘数据与视频数据。本项目采集的图像标注信息已录入Oracle数据库BHIMAGE，相关视频与静态图像已按照MarLIN记录14436《底栖生境视频图像档案》的规范完成归档存储。
