Ziel der Reise / Objectives of Cruise:

AL469 was a routine monitoring cruise in the German EEZ in North and Baltic Sea with focus on dissolved nutrients and trace metals in the water column and trace metals in fines fraction of surface sediments. The first part (North Sea) had to be discontinued after the first five stations and the vessel was forced to two port calls in Cuxhaven of altogether 7 days due to bad weather conditions. The two port calls were interrupted only by a short trial for more measurements in the North Sea which was discontinued shortly after leaving the mouth of river Elbe. Consequently, only five of the planned 55 stations in the North Sea were done (two of them in the river Elbe). After passing the North and Baltic Sea Canal and another port call at GEOMAR Kiel for one night, the second part (Baltic Sea) was conducted smoothly and all ten planned stations were done completely.
