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

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

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

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

5 BREST WIMEREUX ROSCOFF BANYULS MARSEILLE VILLEFRANCHE / MER ARCACHON/ BORDEAUX SOMLIT LUC / MER - 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, 2005) « 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?

11 BREST WIMEREUX ROSCOFF BANYULS MARSEILLE VILLEFRANCHE / MER ARCACHON/ BORDEAUX SOMLIT LUC / MER REQUIREMENTS: Need for a wider use of the data (better communication and easier access) Staff and funding needed (technical work and data processing) QUESTION: is the development of a network of m oored automated systems a priority in France ? To compare: 50 coastal moorings at Woods Hole...
