Yann Ourmieres

I am assistant professor (Maitre de conferences, HDR) at the University of Toulon, in the Mediterranean Institute of Oceanography (MIO). I am a physical oceanographer and my main research interests are the study of the ocean dynamics at different scales from the large scale (open ocean) to the small scales (bay), the passive transport of pollutant, plastic and jellyfish .

When browsing my pages, you will see that most of them are in english but some remain in french, especially those related to my teaching activies, at the Toulon University and the outreach communications mainly to french media.

News

  • September 2018. France 3 video document in the framework of their program 'A mediterranean sea without plastic'. The video shows a sea campaign using drifters to evaluate the surface currents in the area and some numerical work on synthetic drifters mimicking plastic drift.


  • July 2018. Local press video about the IMPACT project, related to the assessment of the currents between Toulon Bay and port-Cros National Park, in order to evaluate connectivity between the industrial habour and the protected area. The video shows a sea campaign using drifters to evaluate the surface currents in the area.
  • Studying the currents to better understand the transport of pollutants . from Groupe Nice-Matin on Vimeo.



  • June 2018. Micro-plastic sampling off the coast of S├Ęte (Nrth-West Mediterranean shelf with "Expedition Septieme Continent" on board of the new ship.
  • Find more about the Expedition Septieme Continent project on their web page.


  • May 2018. A CNRS slide-show on our activty on nano-plastics can be found here in french. It is related to plastic sampling made during our last year campaign (2017) off the Saint-Tropez coast.


  • February 2018. New publication on marine floating debris in the north-western mediterranean region, available from continental shelf research here


  • August 2017. Watch below the trajectory of the mimicked plastic particles (black crosses) apparently randomly placed. They will all end in an anti-cyclonic eddy after a one year drift.
  • This is part of the work going on with the Expedition Septieme Continent project.
  • June 2017. Below is an animation of the GLAZUR64 configuration for the Sea Surface Temperature (SST) from september 2014 to december 2016.
  • April 2017. Back from a week at sea off the St Tropez coasts with my master's students . We have measured the Mediterranean Northern current using CTD, MVP and drifting floats. This year, we have found numerous zones of plankton blooms, as well as dolphins, sunfishes, squids and saw the tail of a supposed fin whale...
