OSCAHR : Observation du couplage à sous-mesoéchelle à haute résolution
Observing physical-biological coupling at the submesoscale thanks to innovative methodologies for sampling in situ at high resolution.
The scientific objectives of the project OSCAHR (Observing Submesoscale Coupling At High Resolution) are to characterize a submesoscale structure and to study its influence on the distribution of biogenic elements and the structure and dynamics of the first trophic levels associated with it.
The strategy is based on an adaptive satellite-based approach and on the use of very recent or new instruments allowing to sample the surface layer at high spatial and temporal frequency.
The original set of multidisciplinary data will allow to validate measurements from remote sensing (radar altimetry, ocean color, reconstitution of planktonic assemblages) in coastal areas.

Les objectifs scientifiques du projet OSCAHR (Observing Submescale Coupling At High Resolution) sont de caractériser une structure dynamique de sous-mesoéchelle et d'étudier son influence sur la distribution des éléments biogènes et sur la structure et la dynamique des premiers niveaux trophiques qui lui sont associés.
Notre méthodologie comprend l'utilisation de nouvelles plateformes d'observation pour l'échantillonnage de la couche superficielle de l'océan à une fréquence spatiale et temporelle élevée. En particulier, un MVP (Moving Vessel Profiler) est déployé avec des capteurs CTD, Fluorescence et LOPC (Laser Optical Particle Counter) et une nouvelle version du cytomètre automatisé en flux est installée pour l'échantillonnage en temps réel et à haut débit des groupes fonctionnels phytoplanctoniques, du microphytoplancton aux tocyanobactéries (dont le Prochlorococcus).
Deux sources d'eau de mer ont été utilisées dans l'OSCAHR : en plus de la prise d'eau de surface à bord, un nouveau système de pompage est développé et testé afin d'échantillonner la colonne d'eau supérieure à une résolution d'un mètre.

You can customize the template to suit your needs.
You can add
and remove fields and fill out default information (e.g. contact
details).
Fields you can not change in the default view may be accessible in the
more
comprehensive (and more complex) advanced view. You can even use the
XML editor
to create custom structures, but they have to be validated by the
system, so
know what you do :-)

- Statement
-
The OSCAHR includes the use of novel platforms of observation for sampling the ocean surface layer at a high spatial and temporal frequency. In particular, a MVP (Moving Vessel Profiler) is deployed with CTD, Fluorescence and LOPC (Laser Optical Particle Counter) sensors.
Furthermore, a new version of the automated flow cytometer is installed for realtime, high throughput sampling of phytoplankton functional groups, from microphytoplankton down to cyanobacteria (including Prochlorococcus). Two sources of seawater have been used in OSCAHR : along with the onboard surface water intake, a new pumping system is developed and tested in order to sample the upper water column at one meter resolution.
