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.

澳大利亚地球科学局（Geoscience Australia）于2008年在西澳大利亚（WA）卡纳文陆架（Carnarvon shelf）开展了一项海洋调查（编号SOL4769），旨在通过同步采集表层沉积物与底内生物（infauna）样本、利用水下拖曳视频及静态摄影观测底栖生境（benthic habitats）、测量海洋潮汐与波浪生成流（wave generated currents），绘制海底地形（seabed bathymetry）图并表征底栖环境（benthic environments）。数据与样本由澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）的“索兰德号”研究船（Research Vessel Solander）采集。海底地形测绘、样本采集及视频断面（video transects）工作在三个调查区域完成，这些区域从宁加洛礁（Ningaloo Reef）向海延伸至陆架边缘，包括：曼杜溪（Mandu Creek，80平方公里）、克洛茨角（Point Cloates，281平方公里）及格纳卢（Gnaraloo，321平方公里）。在曼杜溪与克洛茨角之间（277平方公里）及曼杜溪以北（79平方公里）区域完成了额外的海底地形测绘（未进行样本采集或视频观测）。在克洛茨角调查区域部署了两个海洋学锚系（oceanographic moorings）。该调查还对缪伦群岛（Muiron Islands）东北部52平方公里的区域进行了测绘与采样。本数据集为底内生物类群（infaunal taxa）的样本/物种矩阵，来源于“索兰德号”研究船（RV Solander）SOL4769航次在卡纳文陆架采集的抓斗样本。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果。
