Raw CTD data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 015, April 2015

This is raw Conductivity, Temperature, Depth (CTD) data from the Marion Island Relief Voyage on the SA Agulhas II Voyage 015 from 9 April to 15 May, 2015. The 2015 Marion Relief Voyage on board South Africa’s polar research and supply vessel MV SA Agulhas II offered yet another opportunity to conduct multi-disciplinary ship-based oceanographic research focusing on links and interactions between air and sea, ocean physics, chemistry, biogeochemistry and biology, including microbial, planktic and benthic communities. The overall aim was to continue contributing to the establishment of an oceanographic observation and monitoring system directed by South African research institutions in support of South Africa’s needs – and where possible, the global requirements of the Global Oceans Observing System (GOOS), the Southern Ocean Observing System (SOOS), the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), the Agreement on the Conservation of Albatrosses and Petrels (ACAP), etc.With the declaration in April 2013 of the Prince Edward Islands (PEIs) as South Africa’s first offshore Marine Protected Area (MPA), the outcomes of this cruise will further contribute toward an integrated view and a better understanding of the functioning of the combined island/marine PEI ecosystem.

本数据集源自2015年4月9日至5月15日，由南非极地科研补给船MV SA Agulhas II执行的Marion岛救援航次所采集的原始电导率、温度和深度（CTD）数据。2015年的Marion救援航次为南非极地科研补给船MV SA Agulhas II提供了又一次机会，以开展基于船舶的多学科海洋学综合研究，聚焦于大气与海洋之间的联系及相互作用，包括海洋物理学、化学、生物地球化学和生物学，涵盖微生物、浮游生物和底栖生物群落。总体目标是为南非研究机构主导的海洋观测与监控系统建立贡献力量，并尽可能满足全球海洋观测系统（GOOS）、南大洋观测系统（SOOS）、南极海洋生物资源养护公约（CCAMLR）、信天翁和海燕养护协议（ACAP）等全球需求。随着2013年4月爱德华王子群岛（PEIs）被宣布为南非首个海上海洋保护区（MPA），此次航次的成果将进一步促进对综合岛屿/海洋PEI生态系统功能的全面视角和深入理解。
