The ice cover in the Arctic Ocean plays an important role in the global climate by controlling exchange of momentum and heat between the atmosphere and the ocean. Ice distribution defines not only the heat balance but it also influences the oceanic density distribution through the brine rejection during the cold season, and ice melting during the warm season. The strong processes of exchanging moisture and heat between atmosphere and water occur at the pack-ice openings. This project is part of a systematic study of the Arctic environment and its role in global change which is promoted by NSF's Arctic System Science Program. It is a two year project to utilize data sets existing in the Arctic and Antarctic Research Institute, St. Petersburg, Russia with existing and refined models of increased sensitivity to evaluate the effect of tides on ice production and ice-ocean interaction. This research will investigate four basic tidal constituents, with space resolution of about 20 kilometers, and the role of tides in sea-ice lead formation.

北冰洋的冰盖通过控制大气与海洋之间的动量和热量交换，在全球气候中发挥着重要作用。 冰的分布不仅决定了热平衡，而且还通过冷季期间的盐水排斥和暖季期间的冰融化来影响海洋密度分布。 大气和水之间强烈的湿气和热量交换过程发生在浮冰开口处。 该项目是美国国家科学基金会北极系统科学计划推动的北极环境及其在全球变化中的作用系统研究的一部分。 这是一个为期两年的项目，利用俄罗斯圣彼得堡北极和南极研究所现有的数据集以及灵敏度更高的现有和完善模型来评估潮汐对冰生产和冰-海洋相互作用的影响。 这项研究将研究空间分辨率约为20公里的四种基本潮汐成分，以及潮汐在海冰形成过程中的作用。
