Abstract

Abstract

Double-diffusive staircases are located between the cold, fresh upper water and the warm, salty Atlantic Water in the Arctic Ocean. Based on the data of Moored Profiler, Ice-Tethered Profilers,and Microstructure Profiler, heat flux across the staircases were analyzed. Three staircases in Moored profiles were traced to study the temporal evolution of hydrographical properties of the staircases. Heat flux differences between the upper and lower interfaces were correlated with heat variance of the mixed layer. With the data of Microstructure Profiler, heat flux across the interface was estimated by the assumption of the molecular heat conduction being dominated. When the maximum potential temperature gradient was taken, the result was close to that based on the empirical formula of heat flux. Therefore, it was confirmed that empirical formula of heat flux obtained from the laboratory experiments can be applied in the diffusive convection of the Arcitc Ocean.
