Carnarvon Shelf species level infauna data, Australia (2008)

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）的卡尔纳文陆架（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诱发海流，绘制海底水深地形图并刻画底栖环境特征。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）科考船完成。

调查团队在从宁格罗礁（Ningaloo Reef）向陆架边缘延伸的三个调查区域内完成了水深测绘、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，还在曼杜溪（Mandu Creek）与克洛特斯角（Point Cloates）之间（覆盖面积277平方千米）、曼杜溪（Mandu Creek）以北（覆盖面积79平方千米）区域开展了补充水深测绘（未涉及样品采集与视频作业）。

本次在克洛特斯角（Point Cloates）调查区内共部署了两套海洋学锚系设备。同时，调查团队还对穆伦群岛（Muiron Islands）东北部一片面积52平方千米的区域开展了测绘与样品采集工作。本数据集包含基于“索兰德号”科考船SOL4769航次在卡尔纳文陆架采集的抓斗样品所得到的底内生物分类群样本-物种矩阵。
