This dataset contains model code and input files for studying the energetics of the ocean current under sea ice. The model used in this study is the Massachusetts Institute of Technology general circulation model (MITgcm). Original source code is the MITgcm_c66m. code: contains code configuration for Exp-PD, Exp-D, Exp-P, and Exp-PD100. code_F: contains code configuration for Exp-PF. input_PD: contains parameter settings and input files for the base experiment Exp-PD (initial perturbation + ice-ocean drag). input_D: contains parameter settings and input files for the sensitivity experiment Exp-D (no initial perturbation). input_P: contains parameter settings and input files for the sensitivity experiment Exp-P (no ice-ocean drag). input_PD100: contains parameter settings and input files for the sensitivity experiment Exp-PD100 (a restart of Exp-P from day 100 and is run for 100 days with the ice-ocean drag). input_F: contains parameter settings and input files for the sensitivity experiment Exp-PF (no sea ice model; Forcings include surface stress, shortwave radiation, and heat and freshwater fluxes diagnosed from Exp-PD).
