Abstract

According to the energy balance equation at the ice bottom, the ice bottom energy balance system has been given, and the existence and uniqueness of the solution of the system has been proved. The oceanic heat flux is selected as identified parameter and the the ice thickness deviation as the performance criterion, so that the optimal identification model has been presented. The existence of the optimal solution and the optimality conditions of the optimal identification model have been considered by using the theory of bounded variation. This method to estimate the oceanic heat flux is only controlled by observed ice thickness, which can overcome the calculated bias caused by the technique error of observed temperature and the empirical parameters in other methods. Based on the the field campaigns of landfast sea-ice thermodynamic observation off Zhongshan Station in Prydz Bay, East Antarctica in March 2006 to November 2006, the time series of the oceanic heat flux and the oceanic heat flux fitting function of time has been derived.
