Lord Howe Island Infaunal data

Geoscience Australia carried out a marine survey on Lord Howe Island shelf (NSW) in 2008 (SS06-2008) to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wave-generated currents. Sub-bottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor. Bathymetric data from this survey was merged with other pre-existing bathymetric data (including LADS) to generate a grid covering 1034 sq km. As part of a separate Geoscience Australia survey in 2007 (TAN0713), an oceanographic mooring was deployed on the northern edge of Lord Howe Island shelf. The mooring was recovered during the 2008 survey following a 6 month deployment.

2008年，澳大利亚地质调查局（Geoscience Australia）针对新南威尔士州（New South Wales，缩写NSW）豪勋爵岛陆架（Lord Howe Island Shelf）开展了编号为SS06-2008的海洋调查航次，旨在通过同步采集表层沉积物与底内生物（infauna）样品、岩石岩心钻探、水下拖曳视频（underwater towed video）观测底栖生境，以及测量海洋潮汐与波浪生成流，完成海底水深测深（seabed bathymetry）测绘与底栖环境（benthic environments）特征刻画。本次调查同时采集了海底剖面数据（sub-bottom profile data），用于绘制沉积物厚度与陆架地层（shelf stratigraphy）分布图。科考作业依托国家设施研究船“南方探索者号”（Southern Surveyor）开展。本次航次获取的水深数据与其他已有水深数据（包括LADS）进行融合，生成了覆盖1034平方公里的格网数据集。2007年，澳大利亚地质调查局还开展了另一项独立调查项目（航次编号TAN0713），期间在豪勋爵岛陆架北缘部署了一套海洋观测锚系（oceanographic mooring）；该锚系完成6个月的原位观测后，于2008年的本次航次中被回收。
