Lomonosov Ridge off Greenland (LOMROG) 2007: Chemical and physical oceanography

Conductivity Temperature Depth (CTD) and water sampling were carried out at 26 stations covering parts of the western Eurasian Basin and one station at the East Greenland continental margin. Water was collected using a 24-bottle rosette sampler equipped with 7.5 l Niskin type bottles and a CTD (Sea Bird 911+). When brought back onboard the rosette was moved into a heated double container as quickly as possible to avoid freezing the samples. Water samples were immediately drawn for the individual parameters to be determined in the following order: CFCs, oxygen, dissolved inorganic carbon/pH/total alkalinity, nutrients, oxygen-18, and salinity.本研究于欧亚海盆西部部分区域的26个站位以及东格陵兰大陆边缘的1个站位开展了温盐深（Conductivity Temperature Depth, CTD）测量与水样采集工作。水样采用搭载7.5升尼斯金（Niskin）采水瓶的24瓶式采水架采集，并同步搭载Sea Bird 911+型CTD设备。采水架被带回科考船甲板后，需尽快转移至保温双层容器内，以避免水样冻结。随即按照以下顺序抽取水样并完成各项参数的测定：氯氟烃（CFCs）、溶解氧、溶解无机碳/pH/总碱度、营养盐、氧-18以及盐度。
