Ross Sea Data Buoy Project

该项目包括在罗斯海的年度冰盖上放置一个由9个数据浮标组成的阵列，以确定其移动、形变速率、应变率和散度/产量统计数据。这些浮标将在麦克默多冬季中期的空投任务中从一架C-141飞机上投放。浮标传感器将测量地面气压和温度，并大约每两个小时通过卫星传输这些数据和位置数据。这些浮标预计将运行至少四个月，甚至可能长达十个月。这些数据将用于海冰运动学、海平面压力场和地转风的统计表征。应变率和散度数据与被动微波数据相结合，可以用来评估区域和次区域的冰收支。海冰运动对风场的平均和波动分量的响应可以用来评估风和流强迫的相对重要性，以及内部冰应力的动量耗散的相对重要性。

This project consists of setting out an array of nine data buoys on the annual ice cover of the Ross Sea in order to determine its movement, rate of deformation, strain rates, and divergence/production statistics. The buoys will be dropped from a C-141 aircraft in the course of the McMurdo mid-winter airdrop mission. Buoy sensors will measure surface air pressure and temperature, and transmit this data, as well as location data, via satellite approximately every two hours. The buoys are expected to operate for at least four months, and possibly up to ten months. The data will be used in the statistical characterization of the sea ice kinematics, the sea level pressure field, and the geostrophic wind. The strain rate and divergence data when combined with passive microwave data, can be used to assess the regional and sub-regional ice budget. The sea ice movement in response to the mean and fluctuating component of the wind field may be used to assess the relative importance of forcing by wind and currents, and of the momentum dissipation by internal ice stresses.
