Objectives

The MOOSE concept is based on discussions and recommendations established by scientists during the Villefranche/mer, Banyuls/mer and Marseille workshops (February 2008, June 2008, May 2009) in the context of the MISTRALS program  and in relation to HYMEX, MERMEX and CHARMEX issues.  They aimed at addressing the key scientific and environmental issues relevant for climate change in the North Western Mediterranean basin.

Such network  combines eulerian observatories and autonomous mobile platforms to enlarge and enhance the Mediterranean observation.

  • to observe the long-term evolution of the NW Mediterranean Sea in the context of the climate change and anthropogenic pressures
  • to detect and identify long-term environmental anomalies
  • to build efficient indicators of the health of the NW Mediterranean basin

 

In the MOOSE plan, five scientific questions have been described in term of Work Package:

Nouvelle image objectives

WP1- Mesoscale circulation

The challenges for MOOSE are to properly track and monitor the 1) Northern Current, flowing along the continental slope and recirculating north of the Balearic Islands, 2) the coastal/offshore exchanges, including cascading and 3) the formation of deep/intermediate waters offshore.  This is required to evaluate modifications of the deep water formation processes, which ventilate the basin.

 

WP2- Rivers inputs

The challenge is to propose monitoring strategies to qualify and quantify rivers inputs to the Mediterranean Sea over the long term, from a reduced number of representative sites.

 

WP3- biogeochemical cycles and acidification

This WP aims to observe and understand the nutrients (mainly nitrate, phosphate) and gases (O2 and CO2) dynamics in the NW Mediterranean Sea in relation to physical processes (convection, mixing, stratification) and anthropogenic/natural inputs (atmospheric and continental). The relation with biological production, the carbon export and the physical forcing is also addressed.

 

WP4- Biological communities and biodiversity

The aim is to set up a systematic end-to-end monitoring, including prokaryotic communities, phytoplankton, micro- and meso-zooplankton, in relation to environmental parameters in order to provide an overview of the evolution of biodiversity.

 

WP5- Atmospheric depositions

The challenge for MOOSE is to complete a network to improve the quantification of:

– the anthropogenic deposition.

– the terrigeneous natural inflows from North Africa (Sahara contributions).

– the impact of atmospheric inputs on biogenic and metal traces budget
