The overarching theme of the Research Unit is the analysis and understanding of the freshwater budget of the ocean, including the role, which surface freshwater fluxes (net evaporation minus precipitation plus run-off and sea ice melting) play in changing the salt content in the upper ocean. The Research Unit focusses on the Atlantic, one of the key regions for climate relevant variability, and addresses, specifically, the questions of how and how much the upper Atlantic Ocean and the formation/melting of sea ice contribute to the global hydrological cycle. Work of the Research Unit is, therefore, also concerned with the oceans role in the global hydrological cycle and with the impact of a changing hydrological cycle on the oceans salinity, density and circulation fields. These questions are at the heart of research activities fostered by the World Climate Research Programme (WCRP) and its sub-programmes CLIVAR and GEWEX. Moreover, the subject "water" is central to many questions dealt with under climate impact studies, including precipitation over land, the availability of water for drinking and irrigation, but also sea level rise. The theme addressed in this Research Unit is, therefore, essential for many climate-related and socio-economic questions.

研究部门的总体主题是对海洋淡水预算的分析和理解，包括角色，表面淡水通量（净蒸发减去降水加径流和海冰熔化）在改变上海中的盐含量方面发挥了作用。研究部门的重点是大西洋，这是气候相关可变性的关键区域之一，并提到了有关如何和多少大西洋上大西洋的问题以及海冰的地层/融化有助于全球水文周期。因此，研究部门的工作也与海洋在全球水文周期中的作用有关，以及水文周期不断变化对海洋盐度，密度和循环场的影响。这些问题是由世界气候研究计划（WCRP）及其子程序Clivar和Gewex培养的研究活动的核心。此外，“水”对许多问题的核心是在气候影响研究下涉及的许多问题，包括土地降水，饮酒和灌溉水的可用性，以及海平面上升。因此，该研究部门中提到的主题对于许多与气候有关的社会经济问题至关重要。
