This study explores the fluxes of heat and salt associated with thermohaline staircases in the Beaufort Sea. An inverse model is developed to calculate the vertical transport of properties in the southern portion of the Beaufort Sea directly from observations. The applicability of laboratory derived 4/3 flux law is addressed. Three formulations of the static advectivediffusive equations are discretized on a uniform grid, and inverted using the method of Total Least Squares. The first formulation is based on the classic flux-gradient model, and is analyzed in both one and three-dimensions. The original document contains color images.
