A fully prognostic coupled ice-ocean model is described. The ice model is based on the elastic-plastic constitutive law with ice mass and compactness described by distribution functions. The ice thermodynamics model is applied individually to each ice thickness category. Advection of the ice partial mass and concentrations is parameterized by a fourth-order algorithm that conserves monotonicity of the solution. The ocean is described as a three-dimensional time-dependent baroclinic model with free surface. The coupled model is applied to establish the Arctic Ocean seasonal climatology using fully prognostic models for ice and ocean. Results reflect the importance of the ice melting/freezing in the formation of the thermohaline structure of the upper ocean layer.
This study is part of the Soviet‐Norwegian Oceanographic Programme (SNOP) on ice and water dynamics in the region between Svalbard and Frans Josef Land. The effects of the movements of water and ice on the ice regime are discussed. Due to the scarcity of data, numerical hydrodynamica] simulations are used. The tidal ice drift is visualized on satellite images as elliptically shaped traces in the ice fields formed by grounded icebergs. These traces are a result of the joint action of tides, wind and permanent currents.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
