hydrography of the North Atlantic. To this end we analyse the impact of oceanic resolution in key regions, such as the Gulf Stream and North Atlantic Current regions, the Labrador Sea, and the Denmark Strait [...] n of the adjacent sea ice. Resolving the eddy field in the Greenland Sea is assessed in terms of reducing the deep thermocline bias. The effects of better resolving the Labrador Sea area on reducing the [...] , allowing the explicit representation of eddies and narrow boundary currents in the North Atlantic and Nordic Seas, can alleviate the common model errors. The impact of increased resolution on the modeled
