Presentation transcript:

WP4: fluxes in the North Atlantic : Operational: Continue delivery of VOS and time series data Set up a new VOS line France- Brazil Pirata Moorings – second mooring Install oxygen measurements on UK-Capetown line Synthesis: Neural network versus multiple regressions as tools to interpolate data. Estimates of uncertainties on DpCO2 fields, fluxes Submit first paper on a year of synoptic observations (co-ordinated with all partners) Submit papers on individual data sets and processes e.g. Nuka Arctika, UK-Capetown, Hurricanes,

WP 5: The Southern Ocean Ongoing data collection –Continuous real time measurements of 5 CARIOCA drifters in during four seasons; –ship measurements during OISO cruises, Polarstern cruises and Hesperides cruises. Synthesis –Reports on seasonal to decadal variability of air-sea fluxes as deduced from ship data –Identification of main mecanisms responsible for pCO2 variability in each region; –definition of a strategy to derive seasonal cycle of regional pCO2

WP 6: Model-based flux assessment Build a neural network map –Model based approaches (IFM-GEOMAR) –Data based approaches (LSCE) Understand the processes giving rise to seasonal to internannual variability –Prognostic modelling improved resolution, forcing and BGC (LSCE, LEGOS) –Diagnostic (assimilation) models Improved seasonal representation (AWI) Operational models (LEGOS, Hadley) Improve ecosystem model with biological data (LSCE)

WP 7: Mooring development 
