TRANSMED/HYDROCHANGES - Climate change in the Mediterranean
Responsible : Isabelle Taupier - Letage - MIO
If you think that the Mediterranean is just plain blue and calm, look at the reality with the satellite thermal pictures: eddies and packs of entangled eddies actually fill the (sub)basins of the Mediterranean. Such (mesoscale) eddies induce a high variability of the currents in both time and space.
This complexity then puts oceanographers through an ordeal -and potentially leads to different analyses of the observations.
- What do we know for certain on the water masses circulation (currents) in the Mediterranean nowadays?
- Do all oceanographers agree on the circulations schemas?
- What is the impact of climate change on the temperature and salinity of the Mediterranean?
Thr currents in the Mediterranean
- A hidden face of the Big Blue: currents and swirls in the Mediterranean
- Diagram of currents in the Mediterranean (I. Taupier-Letage, after Millot and Taupier-Letage, 2005)
- General information on the circulation of water masses in the Mediterranean and currents in the Toulon region and the Hyères islands
- A dynamic (and unexpected!) Image of surface currents in the Eastern Mediterranean Basin (trajectories of ~100 surface drifting floats dropped during the EGYPT EGITTO cruise (round: position at the day indicated at the top of the image, line: trajectory of the previous 5j, dashed line: the floating anchor was lost, the float drifts under the effect of the wind mainly).
- Thermal satellite images of the Mediterranean (CMS origin, CNRS / MIO processing, discontinued since 01/04/2017)
Mediterranean evolution/Climate change
Come and dive to rescue scientific instruments stuck on the Mediterranean seafloor at 2300m deep with the ROV Victor 6000 !
February 2018 : recovery of the HydroChange anchorage set up in December 2003 in the central zone of the Gulf of Lions at 2300 m, to study the evolution of the characteristics of the deep water formed.
