Turbulent mixing in the eddy transport of Western Mediterranean Intermediate Water to the Alboran Sea
Research output: Contribution to journal › Article › peer-review
Western Mediterranean Intermediate Water (WIW) is formed in winter in the North-Western Mediterranean. WIW, identifiable as a distinct temperature minimum layer between Atlantic-Mediterranean Interface waters and the denser Levantine Intermediate Water, is carried down the east coast of Spain in anticyclonic mode water eddies, or “weddies” eventually reaching the Alboran sea. A previous detailed analysis of a weddy in the vicinity of the Almeria-Oran front indicated that it could have accounted for 10% of a winter's production of WIW, but this analysis was unable to consider turbulent dissipation. In this study we present microstructure measurements across a similar observation of WIW in the vicinity of the Almeria-Oran front and show that this figure could be conservative by 15–50% due to the turbulent dissipation associated with a weddy.
