Because of its associated northward fluxes of heat and salt, the flow through the Bering Strait is important to the present climate of the northern hemisphere and paleoceanographic proxy data suggests that it has also been critical to the paleoclimate of the region. Recent theoretical work suggests that the mean oceanic conditions in the Bering Strait are only marginally affected by the local wind and local buoyancy forcing. Rather, the primary (responsible) forcings are purported to be the global buoyancy field and the global wind field. Funds are provided to examine this new idea using a hierarchy of models ranging from simple process-oriented numerical models to ocean general circulation and climate models. The project's specific goals are:i. to determine what role the global wind field plays in determining the flow rate through the Bering Strait, and ii. to determine whether the abrupt warming at the end of the last glaciation resulted in part from the opening of the Bering Strait (induced by sea level rise).

由于其相关的热量和盐的北向通量，通过白令海峡的流动是重要的北方和古海洋学代用数据表明，它也是该地区的古气候的气候。 最近的理论研究表明，白令海峡的平均海洋条件只受到当地风和当地浮力的影响很小。 相反，主要（负责）强迫据称是全球浮力场和全球风场。 提供资金，以审查这一新的想法，使用一系列模型，从简单的面向过程的数值模型，海洋环流和气候模型。 该项目的具体目标是：一。以确定全球风场在确定通过白令海峡的流速中起什么作用，以及ii.确定末次冰期结束时的突然变暖是否部分是由于白令海峡的开放（由海平面上升引起）。
