Iron limitation in SO waters and DMS emissions to
the atmosphere S. Belviso (LSCE, Gif-sur-Yvette)
2
Are iron-mediated blooms responsible for DMS
production in SO waters in late summer? We will
describe with high spatial resolution the sea
surface DMS concentration
3
DMSP in the Kerguelen area during late summer
During cruise ANTARES 2, particulate DMSP in the
Plateau was twice higher than offshore.
4
The impact of grazing on the release to solution
of DMSPp OBEX 2
Microzooplankton and mesozooplankton grazing
experiments using 55Fe-radiolabelled nano- and
microphytoplancton. -determination of the
DMSPp-to- 55Fe ratio of phytoplancton
DMS(P)d release during grazing DMSPp/ 55Fe
x 55Fe release
5
The impact of bacteria and solar radiation on the
degradation of DMSPd and DMS OBEX 3
Effect of solar radiation The experimental
protocols are under discussion and will be tested
during the June 2004 workshop in Banyuls/mer in
the framework of the UVECO project
