Rapport d'intervention sur l'épave du chimiquier ECE Intervention report of the ECE chemical wreck
Author(s) :
Lunven Michel
Description :
This intervention is in line with the monitoring study which followed the shipwreck of the chemical tanker ECE 40 miles west of the Cap de la Hague. It aims to carry out some targeted samplings (in deep water, away from the shipwreck) in order to spot and quantify a possible chemical pollution linke...

Methode de cartographie quantitative des ulves "offshore" Method of cartography quantitative of the ulves "offshore"
Description :
Recent studies in the bays of Douarnenez and La Forêt-Fouesnant have proved that drifting stocks of « offshore » ulva exist between -2 and -20 meters depth. These stocks are nearly as important in weight as those located in the tidal zone, the only ones which are generally studied. It is likely that...

Suspended sediments in a macrotidal estuary: comparison and use of different sensors Matières en suspension dans un estuaire à fort marnage : comparaison de différents capteurs
Description :
Measurements made using an in situ particle-sizer (PSA) were compared to those of an optical backscatter sensor (OBS) in a macrotidal estuary. Both estimate the total volume of particles. After comparison with dry weight of suspended matter sampled in the study area, the different measurements were ...

Use of SeaWiFS data for light availability and parameter estimation of a phytoplankton production model of the Bay of Biscay
Description :
Processing SeaWiFS (Sea-viewing Wide Field-of-view Sensor) data provides useful information for the observation and modelling of the phytoplankton production of the Bay of Biscay. Empirical algorithms allow the retrieval of chlorophyll a and non-living Suspended Particulate Matter (SPM) concentratio...

Acquisition de données en vidéo sous-marine sur les ulves offshore de la baie de Douarnenez Data acquisition by underwater video on ulvae offshore in the Bay of Douarnenez (Brittany)
Description :
In the Bay of Douarnenez, assessments of the offshore ulva stock have been carried out in 2004 and 2005 using some submarine video techniques. Altogether, 4 campaigns have been conducted during this period of time, enabling an estimate of the ulva biomass lying on the ocean bed, off the tidal zone, ...

Description :
In biological modelling of the coastal phytoplankton dynamics, the light attenuation coefficient is often expressed as a function of the concentrations of chlorophyll and mineral suspended particulate matter (SPM). In order to estimate the relationship between these parameters over the continental s...

Motility and autotoxicity in Karenia mikimotoi (Dinophyceae)
Description :
Karenia mikimotoi is one of the most common red-tide dinoflagellates proliferating in the eastern North Atlantic and around Japan. Kills of marine fauna are associated with its blooms. In mixed water columns it migrates vertically, while in stratified water columns, the population remains confined w...

In situ video and diffraction analysis of marine particles
Description :
A design for a new underwater video-system to detect and observe suspended particles is presented. Particles are collected and isolated in a rectangular box where they are highly illuminated by a white light plane. The total field of view is determined. The camera, equipped with a remote controlled ...
