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月至6月，由彼得·汤普森（Peter Thompson）牵头，在国家海洋设施“探索者号”（Southern Surveyor）科考船上开展了一次“秋季藻华巡航”任务。本次航次分为三个航段，其中第一航段于5月10日至5月15日执行，聚焦底栖生境。针对底栖环境的采样作业覆盖珀斯附近的两条样带，对应纬度分别为31.71°S与31.76°S，经度跨度为115.63°E至115.15°E，共设置水深分别为30m、40m、50m、75m、100m及150m的采样站位。整个航次全程开展海底声学条带测绘；在全部12个研究站点中，每个站点均完成了底栖橇式拖网采样、抓斗式采泥器取样、底栖视频观测以及CTD（温盐深）剖面测量。
