Ziel der Reise / Objectives of Cruise:

the general scientific goal is to measure the fluctuations of North Atlantic Deep Water (NADW) transport across 16?N in the deep western North Artlantic. The southward transported NADW is the most important cold water branch of the world's oceanic thermohaline circulation, and it is expected from numerical modelling that fluctuations or, in the worst, a break-down would have significant impact on climate. It is well known that the strongest signal of associated currents within NADW transports can be observed in the deep western boundary current off the Americas. However, within the large deep basins, recirculation cells can induce large transport fluctuations even when currents are weak. IFM-GEOMAR in 2000 initially set up an instrumental array along 16?N in the western basin within the experiment MOVE to measure such fluctuations using cross-basin integral methods, namely geostrophic moorings with a number of self recording Conductivity-Temperature-Depth (CTD) instruments (MicroCat, MC) and acoustic tomography. Surface elevations are measured using inverted echosounders in combination with high precision pressure sensors (PIES) which data are to be compared with gravity data from the GRACE satellite mission. Within the deep boundary current, self recording current meters were moored to estimate directly transports.
