Physical and chemical measurements from CTD Niskin collected depth profiles in the East Greenland Current during Autumn 2024.

Physical, chemical and biogeochemical oceanographic properties were measured using sensors and water samples in October 2024, during a research cruise in the sub-polar North Atlantic, aboard the RV Kronprins Haakon. A SeaBird 911 CTD-rosette with attached Niskin bottles were used to collect samples for nutrients (silicate, phosphate, nitrite, nitrate) as well as dissolved organic carbon and total dissolved nitrogen. The water samples will be used to investigate how overturning processes in the Nordic Seas inject vast amounts of dissolved organic carbon (DOC) into the deep ocean. The organisations contributing to these datasets are the School of Ocean and Earth Science at the University of Southampton, the National Oceanography Centre (NOC) and the Scottish Association for Marine Science (SAMS) under the NERC Grant Reference NE/Y002709/1.

2024年10月，研究团队搭乘“哈康国王号（RV Kronprins Haakon）”研究船，在亚极地北大西洋海域开展科考航次期间，利用传感器与海水样品完成了海洋物理、化学及生物地球化学特性的测量。本次科考使用搭载尼斯金（Niskin）采水瓶的SeaBird 911型CTD采水罗经架，采集了营养盐（硅酸盐、磷酸盐、亚硝酸盐、硝酸盐）样品以及溶解有机碳（DOC）、总溶解氮样品。这批海水样品将用于探究挪威海中的翻转环流过程如何将大量溶解有机碳注入深海海域。为本数据集提供支持的机构包括南安普顿大学海洋与地球科学学院、英国国家海洋学中心（NOC）、苏格兰海洋科学协会（SAMS），相关研究受英国自然环境研究理事会（NERC）资助，项目编号为NE/Y002709/1。
