SUPACLARK Geoscientific Data 1990

This dataset contains geoscientific data logged during SUPACLARK cruise on RV Akademik Mstislav Keldysh 8-29 April 1990 in Western Woodlark Basin, Papua New Guinea. These data include logged station coordinates and information for sediment grabs and cores, CTD/hydrocast operations and submersible operations. SUPACLARK was a joint marine geological/geophysical investigation of the Western Woodlark Basin by the USSR Academy of Sciences, CSIRO Australia and the University of Toronto, Canada aimed at furthering knowledge obraind on PACLARK I (1986), II and III (1988) on seafloor hydrothermal activity associated with initial rifting of continental crust where the Woodlark seafloor spreading axis is propagating into the Austral-Papuan continental margin. A program of mamned dives with the USSR's MIR submersibles was integreated with a surface program of narrow beam echo sounding, CTD/hydrocast rosettes and sediment grabs and cores plus some miscallaneous operations.

本数据集包含1990年4月8日至29日期间，在巴布亚新几内亚西伍德拉克盆地（Western Woodlark Basin, Papua New Guinea）由“Akademik Mstislav Keldysh”号考察船（RV Akademik Mstislav Keldysh）执行的SUPACLARK航次所记录的地球科学数据。这些数据涵盖站位坐标日志、沉积物抓样与岩芯信息、CTD/水文投弃作业记录及潜水器作业数据。

SUPACLARK航次是苏联科学院（USSR Academy of Sciences）、澳大利亚联邦科学与工业研究组织（CSIRO Australia）及加拿大多伦多大学（University of Toronto, Canada）联合开展的西伍德拉克盆地海洋地质与地球物理调查项目，旨在深化对PACLARK I（1986）、II及III（1988）航次所获海底热液活动相关知识的理解——该热液活动与大陆地壳初始裂谷作用相关，而伍德拉克海底扩张轴向澳-巴布亚大陆边缘（Austral-Papuan continental margin）的扩展正始于此处。本次航次整合了苏联MIR潜水器的载人下潜计划与水面作业计划，后者包括窄波束回声测深、CTD/水文投弃玫瑰采水器作业、沉积物抓样与岩芯采集及若干杂项作业。
