Dynamics of passive admixture in surface and subsurface external deformation field above an ocean guyot

Abstract

Within the framework of a three-layer quasi-geostrophic model in the f-plane approximation, a numerical study of the effect of an isolated submarine obstacle on the movement of surface and subsurface patches of a neutral admixture transfered by a vertically homogeneous zonal current was carried out. The possibility of partial capture of impurities by quasi-stationary topographic eddy in the vicinity of the submarine obstacle is shown. The role of the initial location (both horizontally and vertically) on the resulting pollution distribution pattern is revealed.
