Under the umbrella of the French initiative MISTRALS (Mediterranean Integrated STudies at Regional And Local Scales) – an interdisciplinary program initiated in 2008 - two projects are directly related to SOLAS science: ChArMEx (Chemistry-Aerosol Mediterranean Experiment, PI F. Dulac, email@example.com) aims to evaluate current situation of the Mediterranean basin atmospheric environment and to anticipate its future development and its impact on regional climate, air quality, marine and continental biogeochemistry. MerMeX (Marine Mediterranean Experiment) is focused on the biogeochemical changes that will take place in the Mediterranean Sea due to natural changes as well as the socio-economic impacts, and how they will affect marine ecosystems and biodiversity. The large program of environmental measures for MISTRALS projects will take place between 2010 and 2020.The first international MISTRALS Symposium will be held in Malta, spring 2011.
PI émi Losno (firstname.lastname@example.org)The FLATOCOA project on dust flux over the southern Ocean (Kerguelen Island) started in 2008. The atmospheric total deposition flux and the atmospheric dust concentration are now sampled for 2 years at Kerguelen. In addition, another station run all during 2010 at Crozet Island to assess gradient information on a 1000 km scale. Campaign stopped at the end 2010 and complete results will not be available before end of 2011 because of very long travel and logistic delays. However, the first year is already measured end shows that deposition flux is in agreement with global models.

This project is about the role of bioaerosols in the iron biogeochemical cycle. Participant are: Marie Cheize (pHD), Anne-Claire Baudoux (post-doc) and Eva Bucciarelli LEMAR/UMR 6539, Plouzané.
This project postulates that bioaerosols could have an impact on the Fe biogeochemical cycle; especially on the organic speciation of Fe. To investigate this hypothesis, three objectives are defined:
Etude des flux de CO2 a l'interface air-mer dans l'océan Atlantique tropical a partir d'un réseau d'observations CO2 (projets CARBOOCEAN et LEFE CYBER). Deux navires marchands (le Colibri et le Rio Blanco) sont equipes d'un systeme autonome de mesure de fugacite de CO2 (détection infrarouge) dans l'océan de surface. 2 bouees PIRATA (6S, 10W et 8N, 38W) sont equipés d'un capteur CARIOCA et d'une optode Anderaa et transmettent les donnees de CO2 et O2 de l'ocean de surface en temps reel par Argos.

A GEOTRACES Mediterranean Planning Workshop took place during 4-6 October 2010 in Nice with goals to plan a GEOTRACES section in the Mediterranean and to setup the SOLAS-GEOTRACES cooperation in the Mediterranean. More than 50 participants met and discussed various aspects of implementing GEOTRACES in the Mediterranean as there is strong interest on trace elements and their isotopes in the Mediterranean Sea, due to the proximity and importance of the ocean-land-atmosphere domains, as well as the variety and intensity of exchanges between these domains.
The SOLAS/IMBER Ocean Acidification working group endorsed the PAGES Workshop on Paleo-ocean Acidification and Carbon Cycle Perturbation Events. The workshop aims to improve the network and interaction between researchers studying the chemical, biological and physical consequences of past carbon cycle perturbations, as well as focus on key questions to improve our knowledge on paleo-ocean acidification and its biogeochemical consequences.
