Ziel der Reise / Objectives of Cruise:

HE497: Field course for students: Water column sampling, acoustic sounding of seafloor and sediment structures, sediment sampling. The vessel left port (Bremerhaven) on September 26 at 13:00 LT and set out to sample a grid of stations in the box 55?20'N/ 005?00'E and 56?00'N/ 007?40' 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 SES2000. A total of 24 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 van Veen grab sampler and at selected stations with a multicorer.On September 30 at 13:00 UTC we left the working area and occupied one station near Helgoland. After after finishing the last station we returned to Bremerhaven, where the journey ended at 13:00 LT on 1 October, 2017.
