Combining high resolution GOCINA topography with ARGO float data

Abstract

We report on impact of the GOCINA dynamic topography and newly available ARGO float data on estimates of the circulation in the North Atlantic. An inverse Finite Element Ocean circulation model is used which seeks for a stationary solution which approaches both types of data and respects equations of motion. The questions we seek to answer are what are the impacts of individual and combined data sets on the circulation. The modelled ocean velocities are compared to the observed float velocities.
