I'm interested in eddies, plankton and carbon flux from the surface to the deep ocean in the global ocean and key areas to estimate the transfert efficiency in food web and carbon pump. I used imaging and observations data, and contribute to the development of models.

Marine megafauna are particularly sensitive to these pressures and there are unfortunately many examples of entire populations disappearing. The case of marine turtles is particularly interesting because, as emblemat...

Other factors such as sex, age or environment of fish were not useful in predicting these values. I...
