PEACETIME objectives are to understand and accurately represent natural and anthropogenic chemical exchanges at the air-sea interface and their impacts on marine ecosystems, today and in the future.
The PEACETIME project aims at extensively in-situ studying and parameterizing the chain of processes occurring in the Mediterranean Sea after atmospheric Saharan dust deposition and to put them in perspective of on-going environmental changes. The ultimate goal was to assess how these mechanisms impact, and will impact in the future, the functioning of the marine biogeochemical cycles, the pelagic ecosystem and the feedback to the atmosphere. The PEACETIME project was centered on a one-month oceanographic cruise in the central and western Mediterranean Sea in May-June 2017.The project is now within its valorization phase: results are currently being published in a inter-journal Special Issue Biogeosciences – Atmospheric Chemistry and Physics. Special issue | Atmospheric deposition in the low-nutrient-low-chlorophyll (LNLC) ocean: effects on marine life today and in the future. https://www.biogeosciences.net/special_issue1040.html
