Objective The LATEX project (Lagrangian Transport EXperiment, P.I. A. Petrenko, F. Diaz) aimed to study the role of combined physical biogeochemical dynamics on a(sub) mesoscale in exchanges of matter and energy between coastal and offshore areas, with the Gulf of Lion as study zone. LATEX09 was one of the preliminary missions to prepare the LATEX 2010 mission which will focus on increasing our knowledge about the (sub) mesoscale processes observed in the Gulf of Lion both through analysis of satellite and in-situ data and hydrodynamic model outputs. Analyzing these different types of data will make it possible to identify an eddy or a filament with a number of given characteristics (life span > 10 days and low to moderate spreading rate) within a stratified physical environment (mixed zone of about 50m). In practical terms, Latex09 involved: Setting up three current measurement moorings for long term monitoring to complement the ocean research cruises of observations and measurements organized in this western part of the Gulf of Lion (LATEX: monitoring a coastal eddy). As in 2008, locating an eddy by in-situ measurements taken by shipboard instruments (shipboard ADCP, TGS and fluorometer on RV Téthys II) and satellite images transmitted on board. CTD stations were then performed to map the biogeochemistry (Chl, suspended matter, nutrients) and to validate the combined physics-biogeochemistry model (Symphonie-Eco3M) and finally to test the iridium transmission Lagrangian buoys.
