BIOSOPE macro-particles 1-     Scientific
objectives
We are proposing two projects A- Estimation of
the stock of particulate matter (PM) gt 100 µm in
the studied water column and the relationship
between PMs spatial pattern and the bio-physical
data. B- Estimation of the distribution and of
the diversity of meso- and macrozooplankton.
Relation between their size-dependent
distribution and ecosystem state.

Different MODELS for different tasks
A UVP 4 standard
D Moored Model
B Single Pressure Case Model for Water Sampler
C Wide Area Towed Model

3- Sampling needs Dig-UVP will be mounted on
the CTD (hopefully) we need a dry lab place for
a large desktop computer, printer and a laptop
computer Zooplankton net sampling according to
the schedule we need a storage place for the
fixed samples preservative buffered
formaldehyde Zooscan/OPC the treatments will
be carry out in France
