MOISE : MOuillage Instrumenté et Suivi biogEochimique
The MOISE project is part of a medium- and long-term approach to monitoring the coastal environment in New Caledonia. Initiated at the end of 2011, this monitoring is based on the installation of a fixed mooring with automatic physico-chemical, optical and biological measurement systems. This approach makes it possible to address the different scales of temporal variability characteristic of the dynamics and functioning of the lagoon ecosystem, including the daily scale. Since 2012, this high-frequency in situ monitoring has been supplemented by monthly monitoring with discrete measurements and vertical profiles over the entire water column; the parameters measured and the methods used are modelled on those of the SOMLIT network, with a view to MOISE's accreditation as an observation station.
Medium and long term observation of the coastal environment in New Caledonia. Climatic variability in tropical zones. Evolution of the monthly, seasonal and interannual variability of the hydrological and biogeochemical characteristics of marine waters at a point located off the Bay of Dumbéa (N-NW of Noumea, New Caledonia) on a depth of 10m.
Measurement of the impact of natural and anthropogenic forcings on the environment, study/quantification of the consequences of this variability, both natural and anthropogenic, on the structuring and functioning of the pelagic ecosystem, and in particular on the appearance of diazotrophic blooms.
Validation of the images obtained by different ocean color sensors by monitoring the variations of the "water color" for an adjustment of the algorithms of calculation of the chlorophyll obtained from satellite reflectance. Possible measurements of the impact of the atmospheric plume of the SLN (Société Le Nickel = nickel treatment by pyrometallurgy) following preliminary work.

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
-
MOISE is composed of a mooring on a shallow (8m) coral reef included in the ReefTemps ("Basse Caui") network measuring every quarter hour temperature, salinity and fluorescence, of a currentometer, and a station sampled monthly using CTD vertical profiles and surface-bottom sampling.
Profiles 0 - 8 m temperature, salinity, turbidity, fluorescence
On surface-bottom sampling: suspended solids, nutrients, particulate matter (CHN), stable isotope 13C/15N, chlorophyll, microbial communities (flow cytometry), pigments
