Biosope macro particles 1 scientific objectives

BIOSOPE – macro-particles

1-     Scientific objectives

We are proposing two projects:

A- Estimation of the stock of particulate matter (PM) > 100 µm in the studied water column and the relationship between PM’s 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. NET SAMPLING.


Methods zooscan and opc for treatment of zooplankton

Methods–ZOOSCAN and OPC for treatment of zooplankton

Triple net

ZOOSCAN

OPC


Biosope macro particles 1 scientific objectives

Easy 3 steps dataacquisition

2) Digitize and analyze thepicture in one mouse click

<15 min

3) Collect the sampleback without lostor degradation

1) Pour and distributethe sample in the cell


Image digitization

200 µm

Image digitization

20% of the whole image

Each picture is 17,500 x 7,000 pixels and contains hundreds of animals


Image analysis

Size distribution (or temporal evolution) of the different

faunistical groups determined by the ZOOSCAN

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 carried out in France


Results

Results

  • 15 methods tested and compared

  • Recognition accuracies higher than 80% are difficult to obtain

  • Our new method (dvf, discriminant vector forest) is both efficient and reasonably fast
