Dynamique des Flux Atmospheriques en MEDiterranee
Multidisciplinary site within MOOSE network (Ligurian Sea), in passage between eastern and western Med Sea. Strong influence of atmospheric deposition influencing productivity and particle export monitored by atmospheric survey (Cap Ferrat) and two permanent sediment traps. Physical parameters recorded from surface to deep waters through monthly visits and permanent deep mooring. Biogeochemical parameters obtained monthly during ship visits. The site is also a way point of gliders and used for cross- validation of bio-parameters (nitrate, oxygen).
Infrastructure Location
Study Area
| Location | Ligurian Sea (NW Mediterranean Sea) | ||
|---|---|---|---|
| Distance from Land | 50 km | ||
| Max Depth | 2350 m | ||
| Oceanographic features of area | Key passage for the water masses coming from the Tyrrhenian Sea (LIW, WMDW) Presence of a strong North Current which limits the influence from the coast Influence of dusts inputs with strong variability of the biomass production (bloom to oligotrophic scenarios) |
