Southern Surveyor Voyage SS 02/2007 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:
(1) use advanced sampling tools and techniques that are, to the extent possible, non destructive
(2) 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
(1) 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
(2) 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
(3) test efficiency of the various biodiversity metrics to determine effectiveness, cost and potential for monitoring other deepwater reserves
(4) provide samples for key taxa that can be used in subsequent genetic research to refine definition and extent of endemicity in deepwater fauna
(5) complete swath mapping of relevant parts of continental slope between Hobart and SW Cape.

This Metadata record describes the imagery data taken with the deep video-system and sediment data taken with a Smith-McIntyre grab. 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for this project have been added to the Oracle data base BHIMAGE and the associated videos and still images have been archived as described in MarLIN record 14436 'Benthic Habitats Video Image Archive'. Sediment data has been processed by GA and integrated into the MARS data base.

本次海洋调查的科学目标分为两个航段执行（第一航段为SS11/2006，第二航段为SS02/2007），具体任务如下：
(1) 采用尽可能实现无损的先进采样工具与技术；
(2) 在科学参考站位采集精准地理配准的基线数据，以量化各类指标（例如各站位的生物多样性指数与捕捞努力量水平）。

此类数据将被整理归档，可供后续调查中的针对性监测工作使用。本次后续调查的目标包括：
(1) 评估塔斯曼海海洋保护区（TSMR）当前管理计划的执行成效：重访1997年曾拍摄的4座海山——Main Pedra、Sister 1、K1与D1，对比捕捞站位与未捕捞站位的变化情况，并完善基线数据；
(2) 可针对塔斯曼海海洋保护区（TSMR）及拟设立的英联邦海洋保护区（Commonwealth MPAs）开展未来绩效评估，涵盖Huon、塔斯曼断裂带（Tasman Fracture），以及视海上作业时长而定的南塔斯曼海隆（South Tasman Rise）与Freycinet；
(3) 测试各类生物多样性指标的应用效率，以评估其用于其他深水保护区监测的有效性、成本与应用潜力；
(4) 采集关键类群样本，用于后续遗传研究，以明确深水动物群落的特有性定义与分布范围；
(5) 完成霍巴特（Hobart）至西南角（SW Cape）之间相关大陆坡区域的条带测图工作。

本元数据记录所描述的内容，为采用深海视频系统获取的影像数据，以及使用史密斯-麦金太尔采泥器（Smith-McIntyre grab）采集的沉积物数据。本项目收集的影像标注数据已录入Oracle数据库BHIMAGE，相关视频与静态影像已按照MarLIN记录14436《底栖生境视频影像档案》的要求完成归档。沉积物数据已由GA处理，并整合至MARS数据库中。
