Ziel der Reise / Objectives of Cruise:

Field course for students: Water column sampling, acoustic sounding of seafloor and sediment structures, sediment sampling. Ther vessel left port (Bremerhaven) on February 24 at 13:00 LT and set out to sample a grid of stations in the box 53?00`N/ 003?30`E and 54?00`N/ 008?00`E. Stations were occupied during daytime for water column and surface sediment work, during nights, we acquired acoustic profiles with a sparker echosounder and echosounder SEL2000. A total of 28 stations were occupied; at each station we deployed a Seabird 911 CTD with rosette sampler to obtain water column profiles and water samples from 5 m above the seafloor and 5 m above sediment surface. The water samples were used for filtration of seston and samples for nutrient analyses. We also routinely sampled the surface sediments at each station with a multicorer.On March 1 we left the working area after finishing the last seismic survey and returned to port in Bremerhaven, where we arrived on June 02 at 00:00 LT. Here the expedition ended.
