Bathymetry grid of Point Cloates of Carnarvon Shelf survey area

Geoscience Australia carried out a marine survey on Carnarvon shelf (WA) in 2008 (SOL4769) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wavegenerated currents. Data and samples were acquired using the Australian Institute of Marine Science (AIMS) Research Vessel Solander. Bathymetric mapping, sampling and video transects were completed in three survey areas that extended seaward from Ningaloo Reef to the shelf edge, including: Mandu Creek (80 sq km); Point Cloates (281 sq km), and; Gnaraloo (321 sq km). Additional bathymetric mapping (but no sampling or video) was completed between Mandu creek and Point Cloates, covering 277 sq km and north of Mandu Creek, covering 79 sq km. Two oceanographic moorings were deployed in the Point Cloates survey area. The survey also mapped and sampled an area to the northeast of the Muiron Islands covering 52 sq km. cloates_3m is an ArcINFO grid of Point Cloates of Carnarvon Shelf survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. This dataset is a contribution to the CERF Marine Biodiversity Hub.

澳大利亚地质调查局（Geoscience Australia）于2008年对西澳大利亚州（WA）的卡那封陆架（Carnarvon shelf）开展了编号为SOL4769的海洋调查，旨在通过同步采集表层沉积物与底内生物样品、利用水下拖曳式视频及静态摄影观测底栖生境、测量海洋潮汐与波浪生成流，绘制海底水深地形图并表征底栖环境。
本次调查的数据与样品采集工作依托澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）的“索兰德号”（Solander）科考船完成。
调查团队在三个自宁格罗礁向陆架边缘向海延展的区域内完成了水深制图、样品采集与视频断面作业，分别为：曼杜溪（Mandu Creek，面积80平方千米）、克洛特斯角（Point Cloates，面积281平方千米）以及纳拉鲁（Gnaraloo，面积321平方千米）。此外，调查还在曼杜溪与克洛特斯角之间（覆盖277平方千米）及曼杜溪以北区域（覆盖79平方千米）开展了补充水深制图工作，未涉及样品采集或视频拍摄。
在克洛特斯角调查区内共部署了两套海洋学锚系装置。本次调查同时对缪恩群岛（Muiron Islands）东北部一片面积52平方千米的海域完成了制图与采样工作。
`cloates_3m`是基于经处理的EM3002水深数据，使用CARIS HIPS与SIPS软件生成的卡那封陆架克洛特斯角区域的ArcINFO网格数据集。
本数据集为英联邦环境研究设施（CERF）海洋生物多样性中心的贡献成果。
