Abstract

It has been known for decades that Lofoten Basin (LB) is a region of high mesoscale activity. This large topographic depression with a maximum depth of 3250 m located in the Norwegian sea is associated with amplification of EKE (eddy kinetic energy) and has some peculiar features of the circulation pattern. Quasi-permanent vortex in the center of the basin is studied with data from ECCO2 eddy-permitting circulation model, altimeter data and trajectories of ARGO buoys. In this study a comprehensive review of all the surveys related to the circulation in LB for the last 50 years is presented in order to structure knowledge and supplement it with the results of new research. The data used in this paper confirm that general water movement in LB is cyclonic along the boundaries of the basin with the distinguishing anticyclonic vortex in the center of the basin. The explanation of this phenomenon is a subject for future research. Refs 25. Figs 3.
