Hydrological data from the Arctic Seas (1987-95)

The investigation of the Arctic Seas started as part of the international Greenland Sea Project (GSP) and is still continued by the Institute of Oceanology.

The main area of exploration is situated in the confluence zone of the Atlantic waters (carried by the Norwegian, Atlantic and North-Spitsbergen currents) and Barents Sea waters.

The hydrological data collected during every expedition of RV 'Oceania' provide valuable scientific material which allows the study of the interannual variability of hydrological conditions in the main area of heat and salt supply for the Greenland Sea and the estimation of their influence on the process of the formation of intermediate water masses in the Greenland Sea basin.

Investigation of the Arctic Front carried out since the year 1993 is the original project of the institute. The general goal is to recognise the structure of the Arctic Front, especially the transfrontal water exchange. The main goal is to determine the role of the mesoscale structures (like gyres and meanders) in the Atlantic water transfer into the Arctic domain (Greenland Sea).
The data set includes:

1987 - 107 stations on the Arctic Seas;

1988 - the profile on the Norwegian Sea - 7 stations,
- the profile along longitude 0deg E - 12 stations,
- the main area - 81 stations,
- the profile between the Faroe and Shetland Islands - 16 stations;

1989 - the profile on the Norwegian Sea - 7 stations,
- the main area - 83 stations,
- the profile along 0deg E - 13 stations,
- the profile between the Faroe and Shetland Islands - 15 stations,
- in Spitsbergen's fjords - 17 stations;

1991 - the main area - 44 stations,
- the profile along longitude 0deg E - 32 stations,
- the Faroe and Shetland Islands - 15 stations,
- in Spitsbergen's fjords - 13 stations;

1992 - the main area (the Arctic Seas) - 46 stations,
- in Spitsbergen's fjords - 32 stations;

1993 - the Arctic Seas, - 63 stations,
- the Arctic Front - 59 stations,
- in Spitsbergen's fjords - 3 stations;

1994 - the Arctic Seas - 67 stations,
- the Arctic Front - 59 stations,
- in Spitsbergen's fjords- 27 stations;

1995 - the Arctic Seas - 93 stations,
- the Arctic Front - 97 stations,
- in Spitsbergen's fjords - 37 stations.

对北极海域的研究始于国际格陵兰海项目（GSP）的一部分，并由海洋学研究所持续进行。主要勘探区域位于大西洋水域（由挪威、大西洋和北斯匹次卑尔根洋流携带）与巴伦支海水域的交汇地带。'Oceania'号船每次探险收集的 hydrological data 提供了宝贵的科学资料，这些资料使得研究该区域（即格陵兰海热量和盐分供应的主要区域）的年际水文条件变化成为可能，并估计其对格陵兰海盆地下层水形成过程的影响。自1993年起进行的北极锋面研究是本研究所的原始项目。总体目标是识别北极锋的结构，特别是越锋面水交换。主要目标是确定中尺度结构（如涡旋和蜿蜒流）在大西洋水域向北极领域（格陵兰海）传输中的角色。数据集包括：
