MOOSE-GE 016

The 2016 cruise MOOSE- Grande Echelle has been conducted on May-June 2016 on the Reseach Vessel  Atalante. Objectives : 1) Maintenance of offshore MOORING (LION, LIONCEAU,  DYFAMED, PLANIER, LACAZE-DUTHIERS) 2) Hydrological casts with seawater sampling for  oxygen, dissolved inorganic carbon, nutrients, pigments  Map of stations Work conducted : Maintenance of five moorings: LION, DYFAMED, LIONCEAU, …

Implementation Plan

The Mediterranean Sea is a mosaic of geographical, physical and ecological domains with very much diversity and contrasts. The major issue is to develop an in situ observing system, capable of capturing all scales of variability, while avoiding any aliasing effects caused by sub-sampling.  This observing system needs to be able to address scales of …

Oceanography modeling

Since a few years, a growing number of 3D hydrodynamics ecosystem coupled models operate in the Mediterranean to answer a large spectrum of questions going from operational oceanography to coastal management or more fundamental problems as the consequences of climate change on marine ecosystems. The constraints defined by the modeler are noticeably different if he …

Workpackage 3 Atmospheric deposition

The main objectives here are to quantify the spatial and temporal distribution of the atmospheric deposition and to qualify aerosol species, which are important in terms of impact on atmospheric optical properties and on marine biogeochemistry (nutrients, contaminants). 3 sites are actually equipped for aerosols filtration and with MTX collector for dry and wet deposition. …

Workpackage 4 Biogeochemical cycles

The Atlantic surface water entering through Gibraltar straits is more or less depleted of nutrient and any biological activity in the surface waters of the Mediterranean Sea tends to reduce the initial stocks. Therefore, the supply of new nutrients to the surface layer relies on mixing with intermediate water or upwelling, on continental weathering, on …

Workpackage 2 Rivers inputs

High frequency and regular monitoring of nutrients and contaminants in rivers are needed to better constrain the spatial distribution and the evolution of anthropogenic compounds in the marine ecosystems. The uncertainty on sources contribution and the transfer mode between the marine reservoirs are important, especially for emergent substances. The Rhone is the largest Mediterranean river …

Workpackage 1 Mesoscale circulation

The challenges for MOOSE are to properly track and monitor 1) the  Northern Current, flowing along the continental slope and recirculating north of the Balearic Islands, 2) the coastal/offshore exchanges, including cascading 3) the formation of deep/intermediate waters offshore ventilating the deep layers.   This is required to monitor the thermohaline circulation, heat, salt budgets …

Workpackage 5 Biodiversity

Oceanic productivity, fishery yields and the net marine sequestration of atmospheric greenhouse gases are all controlled by the structure and function of planktonic communities. Recent studies have documented increases in the magnitude of phytoplankton developments in various parts of the World Ocean in coastal areas as well as in remote oceanic sites. In the coastal …
