Ziel der Reise / Objectives of Cruise:

Field course for students: Water column sampling, acoustic sounding of seafloor and sediment structures, sediment sampling, equipment tests. Stormy weather and rough seas forced us to postpone the cruise one day. The vessel left port (Bremerhaven) on March 31 at 11:00 LT and set course on the shelter of Helgoland island. During the following days we sampled a transect from Helgoland island to the outermost NW corner of the german EEZ. Stations were occupied during daytime for water column and surface sediment work, during nights, we acquired acoustic profiles with a sparker echosounder and echosounder SES2000. A total of 21 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 below water surface. The water samples were used for filtration of seston and samples for nutrient analyses. At a few stations we tested our brand new bottom water sampler. We also routinely sampled the surface sediments at each station with a van Veen grab sampler and - if possible - with a multicorer. On April 4 at 21:00 UTC we left the working area after finishing the last profile and returned to Bremerhaven, where the journey ended at 9:00 LT on 5 April 2012.
