Bathymetry grid south of Mandu 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. north1_3m is an ArcINFO grid south of Mandu 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（Western Australia, WA）的卡那封陆架开展了编号为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、采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，完成海底水深地形制图并表征底栖环境特征。本次数据采集与样品获取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）研究船开展。本次水深测绘、样品采集及视频样带作业共覆盖三个从宁格罗礁向陆架边缘延伸的调查海域，分别为曼杜溪（80平方千米）、克洛特斯角（281平方千米）以及纳拉卢（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）以及曼杜溪以北（覆盖79平方千米）区域开展了补充水深测绘工作，该部分作业未同步开展样品采集与视频观测。在克洛特斯角调查区域内共部署了两套海洋学锚系观测系统。本次调查同时对穆里昂群岛东北部52平方千米的海域开展了制图与样品采集工作。north1_3m是基于经过处理的EM3002多波束水深数据，使用CARIS HIPS与SIPS软件生成的卡那封陆架调查区曼杜溪以南的ArcINFO格网数据集。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果。
