Underwater towed video from the Wessel Marine Park (IN2019_T02)

This record describes the towed video component from the from the Marine National Facility (MNF) RV Investigator research voyage IN2019_T02, titled "Deep seascapes of the Great Barrier Reef: Uncovering submarine canyons and landslides." The voyage took place between October 4 and October 14, 2019 departing from Brisbane (QLD) and arriving in Darwin (NT).Four 1500 m video transects were undertaken across a range of geomorphic features and depth gradients focussed on a deep hole feature within and adjacent to the Wessel Marine Park, on October 11, 2019.The benthic environment in the study area was highly turbid with strong currents, and associated imagery can therefore only be used for habitat classification, coarse morphospecies identification, or defining broad biological communities.Onboard habitat annotations are included as an excel file, with camera positioning included.For access to other End of Voyage (EOV) data from IN2019_T02, see https://catalogue.aodn.org.au/geonetwork/srv/eng/metadata.show?uuid=54158abf-7d02-4e66-8529-48ba6e286d63

本数据集记录了澳大利亚海洋国家设施（Marine National Facility, MNF）“调查者号”（RV Investigator）科考航次IN2019_T02的拖曳视频组分，该航次主题为“大堡礁深海景观：揭秘海底峡谷与滑坡”。本航次于2019年10月4日至10月14日开展，从布里斯班（昆士兰州，QLD）出发，最终抵达达尔文（北领地，NT）。2019年10月11日，研究团队在威塞尔海洋公园（Wessel Marine Park）内部及邻近海域针对一处深凹地貌特征，开展了4条1500米长的视频测线调查，覆盖多种地貌类型与深度梯度。研究区域的底栖环境浊度极高且伴随强流，因此配套影像仅可用于生境分类、粗略形态物种鉴定，或界定宽泛的生物群落。本次数据集附带Excel格式的船载生境标注文件，同时包含相机定位信息。如需获取IN2019_T02航次的其他航次结题（End of Voyage, EOV）数据，请访问：https://catalogue.aodn.org.au/geonetwork/srv/eng/metadata.show?uuid=54158abf-7d02-4e66-8529-48ba6e286d63
