TRANSSIZ - Transsition in the Arctic Seasonal Ice Zone

Date: 19.05.- 28.06.2015
Vessel: Research Icebreaker POLARSTERN (AWI, Germany)
Destination: European Arctic margin
Participants: 51
Disciplines: Oceanography, Biogeochemistry, (Sea-ice) Physics, Biology, Geology

---

The main goal of TRANSSIZ was to conduct ecological and biogeochemical early spring process studies from the shelf to the basins of the European Arctic margin, in order to link past and present sea-ice transitions in the Arctic Ocean. The output of this six week expedition were data from 68 stations, 242 casts, plus the studies conducted during the transit time.
