1 HIGH FREQUENCY MONITORING IN THE SOMLIT NETWORK
WIMEREUX SOMLIT LUC / MER ROSCOFF BREST Eva Bucciarelli (IUEM), Renaud Vuillemin (OCBM), ?, and SOMLIT network HIGH FREQUENCY MONITORING IN THE SOMLIT NETWORK ARCACHON/ BORDEAUX VILLEFRANCHE / MER MARSEILLE BANYULS

2 SOMLIT OBJECTIVES (bi-monthly samplings):
WIMEREUX LUC / MER ROSCOFF BREST WHY USING HIGH FREQUENCY (~HOURLY) SAMPLINGS ? - taking into account local impacts on SOMLIT station - understanding fine temporal scale processes - recording extreme events ARCACHON/ BORDEAUX VILLEFRANCHE / MER MARSEILLE BANYULS

3 - LOCAL IMPACTS AT SOMLIT SAMPLING SITE :
Other parameters / extreme events e.g.: Rhône plume at SOMLIT Marseille WIMEREUX LUC / MER ROSCOFF BREST e.g.: river discharge at SOMLIT Brest: nitrates correlate with salinity and high frequency salinity is recorded at MAREL-IRoise ARCACHON/ BORDEAUX VILLEFRANCHE / MER MARSEILLE BANYULS

4 - UNDERSTANDING FINE TEMPORAL SCALE PROCESSES:
SOMLIT - UNDERSTANDING FINE TEMPORAL SCALE PROCESSES: Towards a better understanding of the ecosystems functioning and physical / biogeochemical modelling: WIMEREUX LUC / MER ROSCOFF E.g.: nitrate variability (one of the main driver of primary productivity in coastal ecosystems) on the California Coast (Prien et al., 2007) E.g.: nitrate variability (one of the main driver of primary productivity in coastal ecosystems) on the California Coast (Prien et al., 2007) BREST 1 analysis/hour 1 analysis every 3 days 1 analysis per week ARCACHON/ BORDEAUX (http://www2.mbari.org/coletti/m1_isus.cgi) VILLEFRANCHE / MER E.g.: Estuarine Turbidity Maximum Oxygen Model (ETNOM) to be developed at UMR 5805 (Arcachon/Bordeaux site) MARSEILLE BANYULS

5 WHAT ABOUT MARINE ECOSYSTEMS?
SOMLIT - RECORDING EXTREME EVENTS: Because extreme climatic events are predicted to increase in frequency and magnitude in response to anthropogenically enhanced greenhouse forcing (e.g.: Diffenbaugh et al., PNAS, ) « extreme precipitation is enhanced over coastal areas dominated by convective precipitation » They cause large, rapid population and community-level changes (e.g.: extreme flood events affected a desert rodent community, Thibault and Brown, PNAS, 2008): « Captured by chance through long-term monitoring, the impacts of such large, infrequent events provide unique insights into the processes that structure ecological communities. » WHAT ABOUT MARINE ECOSYSTEMS?
