- Polar zone: Ross Island
- Title: ISPOL (ANT XXII)
cruise
- Summary: This cruise is part of the SIBClim
project. In this collaborative work with glaciologists, sea
ice ecologists, meteorologists and oceanographers from Germany
(G .Dieckmann, C. Haas; M. Schröder, M. Spindler; AWI)
and other countries (D. Thomas and S. Papadimitriou, UK; J.
Stefels and H. Zemmelinck, NL; J. Dacey, US; T. Worby; Aus.,
J; Launianien; Finl., M; McPhee and R. Muench; US…)
a field experiment (ISPOL, a 50-days drift station) has been
designed to improve our understanding on the role of early
summer physical and biological atmosphere-ice-ocean interactions
in the western Weddell Sea in global processes. The activities
of the Belgian SIBClim team has combined different approaches
to decipher the complex biogeochemical processes governing
the iron, carbon and sulphur cycle in sea ice during the time
sequence involved. Sea ice sampling and measurements activities
have addressed a whole set of physico-chemical and biological
parameters, both in the sea ice itself, in the sea ice brines,
in the sea water below, in the snow above and in the atmosphere
(ice texture, ice fabrics, ice bulk salinity, water stable
isotopes, gas composition, total gas content, particulate material,
filtrate incl. nutrients, carbonate equilibrium, microbial
communities…). Further work involved 14C/55Fe incubations
experiments (3), both “in-situ” and in a ship-based
incubator, and microcosms experiments (2) on bottom algae-rich
samples.
