Underwater video from the Wessel Marine Park (INV2019T02)

Survey INV2019T02 was conducted under the National Marine Facility’s supplementary voyage opportunities on the RV Investigator between the 4th to 14th October 2019, with multiple discrete projects and principal investigators. One of these projects aimed to characterise habitats of targeted areas within Wessel Marine Park, providing crucial baseline information to better understand and manage this marine park, including those sites sacred to local indigenous communities.

As part of this project, 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.

Raw video files are located in folder 'INV2019T02_TOWVID_VIDEOS', named by station number and camera tow. These do not have georeferencing. 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.

调查INV2019T02于2019年10月4日至14日期间，在国家海洋设施的补充航行机会下，由调查船Investigator执行，包含多个独立项目及首席研究员。其中一个项目旨在表征韦塞尔海洋公园（Wessel Marine Park）内目标区域的栖息地特征，为更好地理解和管理该海洋公园提供关键基线信息，包括对当地土著社区具有神圣意义的地点。

作为该项目的一部分，研究人员针对韦塞尔海洋公园内及毗邻区域的深洞特征，在一系列地貌特征和深度梯度上开展了四次1500米视频断面调查。

原始视频文件存储于文件夹‘INV2019T02_TOWVID_VIDEOS’中，按站位编号和拖曳摄像机命名。这些文件无地理参考信息。研究区域的底栖环境因强流而高度浑浊，因此相关影像仅可用于栖息地分类、粗略形态种鉴定或界定广义生物群落。

船载栖息地标注以Excel文件形式提供，包含摄像机位置信息。
