Vertical and Lateral Mixing in the Upper Arctic Ocean: Studies at the SHEBA Ice Camp

这项赠款支持的研究是在北极系统科学（ARCSS）全球变化研究计划的主持下进行的，由海洋科学部和极地计划办公室联合赞助。 即将开展的工作是一个名为SHEBA的五年期重大研究项目的初步步骤，该项目旨在研究北冰洋的热量收支及其对全球变化的影响。 SHEBA的主要目标是：（1）开发、测试和实施北极海洋-大气-冰过程模型，这些模型使用大气环流模型（GCM），明显改进对当今北极气候的模拟，包括其变化性，（2）改进对北极卫星遥感数据的解释，以分析北极气候系统，并为模型输入提供可靠的数据，模型验证和气候监测。 加州大学圣地亚哥分校的研究人员将建造一台仪器，用于测量1997年在拟议的冰营所在地的海冰下热量和动量的垂直和水平通量。 拟议的声纳系统将提供混合过程的准确测量，这将提高模型预测海洋内产生的北极热收支部分的能力。 ??

Research supported by this grant is under the auspices of the Arctic Systems Science (ARCSS) Global Change Research Program and is jointly sponsored by the Division of Ocean Sciences and the Office of Polar Programs. Work to be performed represents preliminary steps towards a major 5-year research project named SHEBA, which is envisioned to study the heat budget of the Arctic Ocean and its impact on global change. The primary goals of SHEBA are: (1) to develop, test and implement models of arctic ocean-atmosphere-ice processes that demonstrably improve simulations of the present day arctic climate, including its variability, using General Circulation Models (GCMs), and (2) to improve the interpre- tation of satellite remote sensing data in the Arctic for analysis of the arctic climate system and provide reliable data for model input, model validation and climate monitoring. Researchers at the University of California, San Diego will build an instrument that will measure the vertical and horizontal flux of heat and momentum under the sea ice at the location of the proposed ice camp in 1997. The proposed sonar system will provide accurate measurements of mixing processes that will improve the ability of models to predict the component of the heat budget of the Arctic that is produced within the ocean. ??
