Geomorphology and Habitats of the Carnarvon Shelf

Flythrough movie showing the bathymetry of Carnarvon shelf, highlighting benthic habitats at Point Cloates. The bathymetric image is derived from multibeam sonar collected in 2008 using a 300 kHz Simrad EM3002 system on RV Solander. Key features on the shelf include a prominent ridge at 60 m water depth and a complex area of smaller ridges and mounds across the inner shelf. The ridges and mounds provide hard substrate for diverse coral and sponge communities. The Carnarvon shelf is a study site for the Marine Biodiversity Research Hub, funded through the Commonwealth Environment Research Facilities (CERF) programme. Survey work was carried out as a collaboration between Geoscience Australia and the Australian Institute of Marine Science. Further information is provided in GA Record 2009/02.

本数据集为展示卡那封陆架（Carnarvon Shelf）水深地形（bathymetry）的飞掠式视频，重点呈现克洛阿特斯角（Point Cloates）区域的底栖生境（benthic habitats）。该水深地形影像源自2008年由搭载于RV索兰德号科考船的300 kHz Simrad EM3002系统采集的多波束声呐（multibeam sonar）数据。该陆架上的典型地貌包括一处位于60米水深的显著山脊，以及内陆架区域一片由小型山脊与海丘组成的复杂地貌区。这些山脊与海丘为多样的珊瑚与海绵群落提供了硬质基底。卡那封陆架是由英联邦环境研究设施（Commonwealth Environment Research Facilities, CERF）项目资助的海洋生物多样性研究中心（Marine Biodiversity Research Hub）的研究站点。本次调查由澳大利亚地质调查局（Geoscience Australia）与澳大利亚海洋科学研究所（Australian Institute of Marine Science）合作完成。更多详细信息可参见GA报告2009/02号。
