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.

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方界限稠密水形成的主要场所，并正在经历与全球变暖有关的重大变化（海水温度变暖、冰盖下降和冬季海洋-空气热损失大幅增加）。然而，它们是全球海洋中观测最差的地区之一，因为在该地区典型的严重亚北极条件下，很难从船只上获得观测结果。我们将在2001-2010年期间利用Argo浮标、海豹传感器和研究船的剖面观测数据，开发一个新的高纬度海洋温度（T）和盐度（S）数据集。新的数据集对于确定拉布拉多和北欧海最近的变化具有根本重要性。它将作为一个社区资源，用于未来确定气候变化对全球海洋环流这一关键区域的影响，并将被PI和Co-I在其随后的研究中大量使用。
