LES ECOSYSTEMES MEDITERRANEENS FACE AUX CHANGEMENTS CLIMATIQUES. Arrivee au sommet de la tour a flux de la station d'etude INRA de la pinede a pin d'Alep face au changement climatique, situee en foret de Fontblanche. L'echafaudage, qui mesure une vingtaine de mètres de hauteur, est equipe de capteurs meteo et sert a mesurer les concentrations en gaz carbonique immediatement au dessus de la canopee ("Eddy covariance"). Cette station INRA (un quadrat clôturé de 80x80m) a été installee par l'INRA d'Avignon en 2007 et simule une aridification du climat en interceptant 30% des precipitations.LES ECOSYSTEMES MEDITERRANEENS FACE AUX CHANGEMENTS CLIMATIQUES.

Monitoring of sponge respiration - Aquarius Reef Bas Florida ; non-calcifying reef organisms like sponges will likely benefit from negative impacts to corals caused by ocean acidification and climate change; research data suggest that water passing through a filter feeding X muta sponge drops more than 0.01 pH units, a significant fraction of the 0.1 drop that has already resulted from the acidification of the ocean by the increase in atmospheric carbon dioxide in recent decades.; scientists try to understand how to distinguish local acidification processes, like that from sponge respiration, from the global scale changes now occurring around the world. Only in this decade have scientists fully realized the threat of global acidification to calcifying organisms such as corals. Marine scientists around the world are now attempting to provide the information that we need to both understand and manage this important problem; field work, experiments and scientific setups of the AUG 2011 Research Mission: Ocean Acidification: Controls on Reef pH; Principal Investigator: Dr. Chris Martens, UNC Chapel Hill<br>Co-Principal Investigator: Dr.Niels Lindquist (left), UNC Chapel HillMonitoring of sponge respiration - Aquarius Reef Bas FloridaMonitoring of sponge respiration - Aquarius Reef Bas Florida ; non-calcifying reef organisms like sponges will likely benefit from negative impacts to corals caused by ocean acidification and climate change; research data suggest that water passing through a filter feeding X muta sponge drops more than 0.01 pH units, a significant fraction of the 0.1 drop that has already resulted from the acidification of the ocean by the increase in atmospheric carbon dioxide in recent decades.; scientists try to understand how to distinguish local acidification processes, like that from sponge respiration, from the global scale changes now occurring around the world.
