Dense water formations in the North Western Mediterranean: from the physical forcings to the biogeochemical consequences

Last Updated: 16 October 2017

This is a joint special issue with JGR-Oceans and JGR-Atmospheres.

The North Western Mediterranean is a specific region playing a key role for the hydrology and biogeochemistry of the whole basin due to (1) the deep convection that redistribute organic and inorganic matters all over the water column, and (2) the subsequent intense spring bloom that represents the most important biological process of the basin at the origin of carbon exports. The MerMeX, HyMeX and MOOSE components of the MISTRALS program focus on the impact of winter convection on the water cycle, redistribution and stoichiometry of matter, development and succession of biological community over an annual cycle, and their potential evolutions. This special section compiles the major results of an unprecedented intensive and innovative effort of observation and modelling over a full annual cycle from June 2012 to September 2013. Ship-based operations, autonomous platforms (gliders, Bio-Argo floats, mooring lines), remote-sensing and coupled modelling were combined to better characterize and understand the NWM dense water formation phenomena, including the associated physical processes, and the biogeochemical response of the pelagic ecosystem.
