. . .when we suspended two clocks constructed from two hooks imbedded in the same wooden beam, the motions of each pendulum in opposite swings were so much in agreement that they never receded the least bit from each other and the sound of each was always heard simultaneously. The cause is that the oscillations of the pendula, in proportion to their weight, communicate some motion to the clocks (Huygens 1967).
We enjoy looking at the connexion, sometimes hardly perceptible, between physical and biological processes happening in the ocean at different temporal and spatial scales. In particular, we look at the mechanisms that control marine primary production, as for example intermittent nutrients supplies to plankton communities. For that, we use a combination of satellites images, time series data analyses, physical and biological observations from specific cruises, and ocean model simulations. We are specially interested on taking measurements of small-scale turbulence in order to describe the temporal and spatial variability of microturbulence in the ocean, quantify the inputs of new nitrogen into the upper layer, and understand the link between turbulent mixing, nutrient supply and plankton communities.
