The PIs have successfully developed a high-resolution unstructured-grid, finitevolumecoupled ice-ocean model for the Arctic Ocean (AO-FVCOM). AO-FVCOM has beenvalidated via comparison to observed data under climatological conditions. Now they seek support to work on the following three tasks: 1) Calibrate and validate AO-FVCOM using observational data collected in the Canada Arctic Basin and its marginal Chukchi and Beaufort Sea. This region is chosen for intense study because it has the most pronounced loss of sea ice extent and thickness in recent years and its unprecedented coverage by multiyear national and international field and modeling studies. 2) Apply the new calibrated and validated AV-FVCOM to investigate the following scientific topics: a) improve understanding of the circulation of the Alaskan Coastal Current and Pacific and Atlantic waters in the study region, b) revisit scientific questions and methodological problems associated with shelf-basin exchange (SBE) processes in the region, and c) apply AO-FVCOM to investigate transformations and transports of fresh water (both liquid and solid) from freshwater sources (Bering Strait, rivers, central Beaufort Gyre, precipitation) towards the North Atlantic Ocean via Fram and Canadian Archipelago Straits. 3) Train a Ph.D. student in advanced Arctic Ocean modeling.Successful completion of this project will provide an additional protocol for modeling Arctic Ocean processes. It will also advance understanding of the circulation and mixing processes in the Arctic Ocean, processes which will grow in socio-economic importance with increasing ice loss and development activities in this part of the globe.

PI成功地为北极海洋（AO-FVCOM）开发了高分辨率的非结构性网格，有限的冰山模型。通过在气候条件下观察到的数据进行比较，AO-FVCOM已被估算。现在，他们寻求支持以下三个任务的支持：1）使用在加拿大北极盆地及其边际chukchi和Beaufort Sea收集的观察数据进行校准和验证AO-FVCOM。之所以选择该地区进行激进研究，是因为近年来它的海冰范围和厚度最为明显，并且其由多年的国家和国际领域以及建模研究的前所未有的覆盖范围。 2）应用新的校准和验证的AV-FVCOM来调查以下科学主题：a）提高对研究区域中阿拉斯加沿海电流，太平洋和大西洋水域的循环的了解，b）复兴科学问题和方法论问题，以及与货架 - 巴斯蛋白交换相关的科学问题和方法论问题，以及在该地区的固体和ccom的固体转换（应用于新鲜的水）（应用于新鲜的水）（应用于新鲜的饮水（都可以调查）（同时调查）（同时使用新鲜的饮水）（同时调查）（同时使用新鲜的饮水（均应）（均可调查）（同时调查）（同时使用新鲜的饮水（均应）（海峡，河流，中部博福特·格雷（Beaufort Gyre），降水）朝北大西洋朝北大西洋（Fram）和加拿大群岛海峡。 3）训练博士学位高级北极海洋建模的学生。该项目的成功完成将为北极海洋工艺建模提供附加的协议。 它还将提高对北极海洋中的循环和混合过程的了解，这些过程将随着全球这一部分的冰损和发展活动的增加而增长的社会经济重要性。
