95290545 Wunsch In this project, the PIs will use a global inverse model based on long-line hydrographic data from the World Ocean Circulation Experiment (WOCE) plus some other sections that pre-date WOCE, to investigate oceanic budgets of heat, fresh water, oxygen, and nutrients, and the interchange of these components with the atmosphere. The model is based on the geostrophic inverse method, and can be updated with new hydrographic data, as well as with other types of data such as those from floats, current meters, and altimetry. A particular feature of this approach is the ability of the model to quantitatively estimate uncertainties in the results. Additional methods for determining the time variability of ocean circulation will also be sought. ***

95290545 Wunsch在该项目中，PI将使用基于世界海洋环流实验（WOCE）的长线水文数据以及早于WOCE的其他部分的全球逆模型，以调查海洋热量，淡水，氧气和营养物的收支，以及这些成分与大气的交换。 该模型是基于地转反演方法，并可以更新新的水文数据，以及与其他类型的数据，如那些从浮子，流速计，测高。 这种方法的一个特点是模型能够定量估计结果中的不确定性。 还将寻求确定海洋环流随时间变化的其他方法。 ***
