Post Cruise Report, Prydz Bay and Mac. Robertson Shelf, Antarctica, January - March 1993

The Natural Variability Sub-program of the Co-operative Research Centre for Antarctic and Southern Ocean Environments aims to study past environmental change by examining ice core and sedimentary records in Antarctica and the Southern Ocean. As the first stage in marine sedimentological studies, Voyage 7 of the Australian National Antarctic Research Expeditions (ANARE) 1992/1993 shipping season included a geoscience program comprising echo sounder traverses, gravity coring and grab sampling of the Antarctic continental shelf and slope on the Mac. Robertson Shelf and in Prydz Bay. This record describes the preliminary results of the voyage and presents location information for core and grab samples and preliminary descriptions of grab samples and lists of subsamples taken by associated research programs.

南极与南大洋环境合作研究中心 (Co-operative Research Centre for Antarctic and Southern Ocean Environments) 自然变性子项目，旨在通过解析南极及南大洋的冰芯与沉积记录，探究古环境变化历程。作为海洋沉积学研究的先期阶段，澳大利亚国家南极研究探险队 (Australian National Antarctic Research Expeditions, ANARE) 1992/1993航季的第7次航程搭载了一套地球科学作业方案，涵盖麦克罗伯逊陆架 (Mac. Robertson Shelf) 与普里兹湾 (Prydz Bay) 区域南极大陆架及陆坡的回声测深剖面测量、重力岩芯取样与抓斗取样作业。本数据集记录了本次航程的初步研究成果，提供了岩芯与抓斗取样样品的位置信息，同时给出了抓斗取样样品的初步描述，以及相关研究项目所获取的子样本清单。
