Inverse Estimate of the North Atlantic Circulation: Influence of the fine resolution GOCINA dynamic topography

The circulation in the North Atlantic subpolar gyre and the NordicSeas has been improved by assimilating the GOCINA altimetry into aninverse finite-element ocean circulation model. The inverse modelseeks for a density field which is close to the density data and hasa large-scale ocean circulation wi...
