NSW Marine Estate Towed Video Imagery

Raw downward facing still imagery of the seabed over the NSW continental shelf acquired using NSW government's (Department of Climate Change Energy Environment and Water) towed video system aboard RV Bombora. Acquisition is ongoing (>2015) predominantly funded by the department under Coastal Reform Climate Change Fund project 'State-wide Science' and/or by various collaborative agencies (DPI; Parks Australia; FRDC) and educational institutions (UoW: UTas). Imagery is captured over areas to 1) ground-truth seabed typologies and validate habitat boundaries derived from multi-beam echosounder (MBES) surveys (www.aodn.org.au or www.ausseabed.gov.au) and/or 2) habitat assessments and monitoring to capture broad distribution of seabed benthic communities. For biodiversity-type assessments, imagery is captured, and transects/sites are selected in a sampling design in accordance with the Australian Field Manuals for Marine Sampling. Imagery captured is generally of benthic habitats in 10-120m of water depth over the NSW inner shelf. Georeferenced (XYZ) and time-stamped (UTC) still imagery is accessible via SEED, the online annotation platform Squidle+ and SeaMap Australia.

本数据集包含澳大利亚新南威尔士州（New South Wales, NSW）大陆架海域的原始俯视视角海底静态影像，数据由新南威尔士州政府气候变化、能源、环境与水务部（Department of Climate Change, Energy, Environment and Water）搭载于“邦博拉号”科考研究船（RV Bombora）的拖曳式视频系统采集。数据采集工作自2015年起持续开展，主要由该部门通过“海岸改革与气候变化基金”下设的“全域科学”（State-wide Science）项目资助，同时亦得到多家合作机构——新南威尔士州初级产业部（DPI）、澳大利亚公园管理局（Parks Australia）、渔业研究与发展公司（Fisheries Research and Development Corporation, FRDC）——以及两所教育机构：卧龙岗大学（University of Wollongong, UoW）与塔斯马尼亚大学（University of Tasmania, UTas）的协作支持。本次影像采集的核心目标包括：1）为海底底质类型分类提供地面真值验证数据，并验证由多波束测深仪（multi-beam echosounder, MBES）勘测（可访问www.aodn.org.au或www.ausseabed.gov.au）所得的生境边界；2）开展生境评估与监测，以获取海底底栖生物群落的整体分布情况。针对生物多样性类评估，影像采集与样带、采样点的选取均严格遵循《澳大利亚海洋采样野外手册》（Australian Field Manuals for Marine Sampling）的采样设计规范。所采集的影像主要覆盖新南威尔士州大陆架内缘水深10至120米范围内的底栖生境。带有地理坐标（XYZ）与协调世界时（Coordinated Universal Time, UTC）时间戳的静态影像，可通过SEED、在线注释平台Squidle+以及澳大利亚海图项目SeaMap Australia获取。
