Raw CTD data from the Marion Island Annual Relief Voyage on the SA Agulhas II Voyage 024, April 2017

This is raw Conductivity, Temperature, Depth (CTD) data from the Marion Island Annual Relief Voyage on the MV SA Agulhas II Voyage 024, 06 April to 12 May 2017. The 2017 Marion Relief Voyage offered the fifth opportunity to conduct multi-disciplinary, shipbased marine research focusing on links and interactions between air and sea, ocean physics, chemistry, biogeochemistry and biology, including microbial, planktic and benthic communities on board South Africa’s polar research and supply vessel MV SA Agulhas II en route to, and around, the sub-Antarctic Prince Edward archipelago. The overall aim was to continue contributing to an oceanographic observation and monitoring system directed by South African research institutions in support of South Africa’s needs – and where possible, in support of global requirements of inter alia the Global Oceans Observing System (GOOS), the Southern Ocean Observing System (SOOS), the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), and the Agreement on the Conservation of Albatrosses and Petrels (ACAP). With the declaration on 9 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.

本数据集为MV SA Agulhas II航次024号在2017年4月6日至5月12日间，于马利恩岛年度巡访期间所采集的原始电导率、温度、深度（CTD）数据。2017年马利恩岛巡访为第五次开展以船舶为载体的多学科海洋研究，旨在聚焦于大气与海洋之间的联系及相互作用，以及海洋物理学、化学、生物地球化学和生物学等领域的研究，包括船上南非极地研究与补给船MV SA Agulhas II在前往及环绕亚南极爱德华王子群岛途中所进行的微生物、浮游生物和底栖生物群落研究。总体目标在于持续为南非研究机构主导的海洋观测与监控系统贡献力量，并在可能的情况下，支持全球海洋观测系统（GOOS）、南大洋观测系统（SOOS）、南极海洋生物资源养护公约（CCAMLR）以及信天翁和海鸽养护协议（ACAP）等全球需求。随着2013年4月9日爱德华王子群岛（PEIs）被宣布为南非首个海上海洋保护区（MPA），此次巡访的成果将进一步促进对综合岛屿/海洋PEI生态系统的功能和运作机制的全面视角与深入理解。
