Abstract The 26"1 voyage of RV METEOR to the North Atlantic, the Skagerrak, the Norwegian, East Greenland and Barents Seas consisted of three legs whose research programs served several . large integrated, and multi-disciplinary projects. During the first leg, M 26/1, the programs were related to WOCE (World Ocean Circulation Experiment), specifically the North Atlantic overturning rate determination and to the JGOFS project (Joint Global Ocean Flux Study). Of seven WOCE moorings three (M2, El and E2) had to be dredged because of release problems and/or possible loss of buoyancy. Two of them (F2 and W2) released and surfaced as planned; another two moorings (D2 and AZ) could not be located for different reasons. Hydrographic parameters for characterization of water masses were also obtained at all sites as well as at those of the JGOFS moorings (Ll, L2, L3). All three of these were successfully redeployed during M 26/1 after they had been recovered in early summer of 1993 by the deep submersibles MIR. Throughout most of M 26/1, a continuous and contamination-free pumping system was deployed and a composite transect of chemical parameters measured. Among them are the nutrients, organic acids, biomarkers and trace elements. They are important basic data for several of the JGOFS subprojects which examine the interaction of dissolved and particulate trace constituents in relation to seasonal and meridional particle production and flux. During the second and third legs, M 26/2 and M 26/3, the research programs served the Sonderforschungsbereich 313 (Environmental Change in the northern North Atlantic) as well as those of two European Community projects SEEP (Gas and Water Seepage on the European Continental Margin) and ENAM (European North Atlantic Margin). Other projects, addressing the well-known cold water carbonates of the Norwegian Sea (Boreale Flachwasserkarbonate) and the history of post-glacial rebound of the Scandinavian shield (Hebungsgeschichte Skandinaviens), were also part ofM 26.
