WAMSI Node 1.1.3 - Marmion Benthic Survey 2007

In May-June 2007, an "autumn bloom cruise" was conducted on the National Marine Facility, Southern Surveyor, led by Peter Thompson. The voyage was conducted in three legs, with a the first conducted from May 10th to May 15th focused on benthic habitats. Benthic based operations were performed over two transects near Perth at 31.71ºS and 31.76ºS from 115.63ºE to 115.15ºE with stations at depths of 30, 40, 50, 75, 100 and 150m. Acoustic swath mapping of the sea-bed was conducted during the entire voyage; at each of the 12 study sites, benthic sled dredges, sediment grabs, benthic video and CTD casts were completed.

2007年5—6月，由彼得·汤普森（Peter Thompson）牵头，在国家海洋科考船“南方探索者号”（Southern Surveyor）上开展了“秋季水华巡航”任务。本次航程分为三个航段，第一航段于5月10日至5月15日实施，重点聚焦底栖生境调查。针对底栖生境的作业在珀斯附近的两条调查断面展开，断面纬度分别为南纬31.71°和南纬31.76°，覆盖经度范围115.63°E至115.15°E，站位水深依次为30米、40米、50米、75米、100米及150米。全航程全程开展海底声呐条带测绘；在全部12个研究站点中，每个站点均完成了底栖拖网采样、沉积物抓斗取样、底栖视频观测及温盐深仪（CTD）剖面测量。
