A Novel Temperature and Salinity Dataset for Northern High LAtitude Seas (ATLAS)

拉布拉多海和北欧海是全球气候系统的关键要素。它们是全球海洋环流北端密集水形成的主要地点，正在经历与全球变暖相关的重大变化（海洋温度变暖、冰盖下降和冬季海洋-空气热损失的强烈增加）。然而，由于在该地区典型的严重亚北极条件下难以从船舶获得观测结果，它们是全球海洋中观测最差的区域之一。我们将开发一个新的高纬度海洋温度(T)和盐度(S)数据集，利用剖面Argo浮标、密封传感器和研究船在2001-2010年期间的观测数据。新的数据集对于确定拉布拉多海和北欧海最近的变化具有根本的重要性。它将作为未来确定气候变化对全球海洋环流这一关键区域的影响的工作的一种社区资源提供，并将在PI和Co-I随后的研究中大量使用。

The Labrador and Nordic Seas are key elements in the global climate system. They are the main sites for dense water formation at the northern limit of the global ocean circulation and are experiencing major changes (warming sea temperatures, falling ice cover and strong increases in winter sea-air heat loss) associated with global warming. However, they are amongst the most poorly observed areas of the global ocean due to the difficulty in obtaining observations from ships under the severe sub-Arctic conditions typical of this region. We will develop a novel high latitude ocean temperature (T) and salinity (S) dataset using observations from profiling Argo floats, seal-borne sensors and research ships in the period 2001-2010. The new dataset will be of fundamental importance for determining recent changes in the state of the Labrador and Nordic Seas. It will be made available as a community resource for future efforts to determine the impacts of climate change on this key region of the global ocean circulation and will be heavily used by the PI and Co-I in their subsequent research.
