Carnarvon Shelf species level infauna data

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 wave generated 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.

澳大利亚地质调查局（Geoscience Australia）于2008年在西澳大利亚州（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、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诱导海流，开展海底测深制图并表征底栖环境特征。本次调查的数据采集与样品获取工作依托澳大利亚海洋科学研究所（AIMS）的“索兰德号”（RV Solander）研究船完成。

调查团队在三处从宁格罗礁向陆架外缘延伸的海域完成了测深制图、样品采集与视频样带作业，分别为：曼杜溪（80平方千米）、克洛阿特斯角（281平方千米）以及纳拉卢（321平方千米）。此外，团队还在曼杜溪与克洛阿特斯角之间（覆盖面积277平方千米）及曼杜溪以北（覆盖面积79平方千米）区域开展了额外的测深制图工作，未进行样品采集与视频拍摄。在克洛阿特斯角调查海域内，共部署了两套海洋观测锚系。本次调查同时对米尔恩群岛东北部一片52平方千米的海域开展了测深制图与样品采集工作。
