- Abstract
-
DYFAMED is a model site which represents the physical and biogeochemical conditions found off the Mediterranean coast (fast water residence times, atmospheric dust, changes in deep water, etc.). It is recognised as being one of the reference site for oceanographic observation (OceanSITES).
- Purpose
-
The main aim of the observations conducted at this site is to observe the evolution of the marine ecosystem in the Ligurian Sea and its reaction to climatic and man-made effects and their changes over time. The DYFAMED site is off the coast of the Ligurian Sea (30 miles from NICE, 2350m above the sea floor), where the Levantine waters from the eastern basin flow towards the Golf of Lion.
This site is protected from the influences of the coast by the North Current, thus forming a hydrological front. This site experiences high biogeochemical variability, from mesotrophic (spring bloom) to oligotrophic conditions (summer season). These conditions are significantly limited by deposits of atmospheric dust and highly variable hydrological conditions (mixed during winter compared with clear stratification during the summer). All of these factors lead to materials (and carbon) being drifted toward deep water.

Data collected on the DYFAMED site is public data sent in real time and non-real-time to the CORIOLIS and SISMER data centres. Old data (1991 – 2007) is archived locally on the OOV network.
All measurements stem from the JDOFS and SOMLIT protocols. Data quality monitoring is conducted regularly by inter-comparison (nutrients, organic carbon), by regular use of standard (nutrients, oxygen, salinity), or by in-situ measurements to correct raw data (salinity, oxygen, nitrates).
Data collection methods are common to the entire MOOSE network and only change when data accuracy needs to be improved.
Measurements are taken on a site (Eulerian measurements), by boat (monthly), and by anchoring (continuous).
Lagrangian measurements are also taken between Nice and Dyfamed (underwater gliders).
