ADAMANT

ADAMANT project aimed at quantifying the role of atmospheric deposition of nitrogen (N) and phosphorus (P), as driver for changes in the Mediterranean’s marine productivity, through modeling and experimental investigations. The marine physical / biogeochemical model is forced by an atmospheric chemistry / transport / deposition model. The atmospheric deposition of nutrients and their long-term variability were examined as well as their effect on the oceanic biogeochemistry from preindustrial period to 2100. Results from mesocosm experiments showed that nitrogen and phosphorous atmospheric deposition enhanced primary production. Simulations indicated that atmospheric deposition was significant in the regulation of the unusually high N/P measured in the Mediterranean Sea.
