I finished my PhD in ocean waves numerical modelling in 2017 in theLaboratory for Ocean Physics and Satellite remote sensingin Brest (France) under the supervision ofFabrice Ardhuin.I am mainly working onSKIM, a satellite mission proposal to the european space agency.

I am also working on improving surface waves numerical models such as WAVEWATCH(R)III, particularly by better accounting for the so-called short waves (10 cm to 10 m wave length).

On this page, you will find a presentation of mywork, a list ofpublicationsand a list of useful links.



SKIM project

SKIM is satellite mission proposal to the European Space Agency (ESA), submitted in 2019 as part of ESA Earth Explorer 9 program. SKIM would be the first satellite designed for the measurement of the total surface current vector, in other words the true current and the Stokes drift. Such a mission would improve our knowledge on surface currents, known only through altimeters nowadays.

The SKIM project led to a full feasability study, for which only two satellite missions are retained every year. A detailed report resulted, that was officially presented to ESA selection comittee in Cambridge, on July 16th and 17th 2019 ( available in replay ).

My contributions to this project are multiple

  • high resolution (2 km) multi-forcings (wind, surface currents and sea-ice) numerical modeling of sea states using WaveWatch IIIin various regions of the globe (10 regional grids, 5 To data set)
  • elaboration of an innovative method for modelled high resolution surface currents validation
  • performance diagnostics of SKIM products (using spectral methods especially)
  • reconstruction algorithms for the SKIMulator
  • organization of the workshop Doppler Oceanography from Space (97 participants).

Short ocean surface waves and numerical models

Actual sea-state numerical models performances are reaching their limits especially due to a poor representation of short surface waves (10 m to 10 cm wave lengths).

Much of my research work has been dedicated to gathering measurements and bringing improvements to sea-state numerical models such as WaveWatch III.

I contributed, particularly during my thesis, to the elaboration of

  • a method for the analysis of seismo-acoustic records in terms of short waves directional properties
  • a method for the analysis of optical data (stereo-video), improving our knowledge of short waves propagation directions
  • an improvement of the numerical model WaveWatch III (implementation of new physics)
  • a theoratical explanation and a calculation of the physical process responsible for the observed short waves properties (work in progress).
