Zirkulation und Wassermassenbildung im Weddellmeer
AbstractThe thermohaline circulation of the global ocean is primarily driven by water mass formation in the northern and southern Atlantic Ocean and its adjacent seas. Lateral and vertical mixing in the northern North Atlantic generate the North Atlantic Deep Water which occupies the major part of t...
