Última Caractérisation des effets du réchauffement climatique sur l'océan superficiel au cours des 50 dernières années ArchiMer Hamon, Mathieu. To identify and characterize the effects of global warming is one of the major scientific challenges of this new century. The rise of sea level, the hydrological changes are some consequences of this phenomenon which will influence all forms of life on Earth. Due to its high thermal capacity, it is estimated that 84% of the energy developed by global warming is stored in the first layers of the ocean. However, it is rather difficult to assess its overall impact over the last 50 years because the ocean is not warming uniformly and the inhomogeneous sampling (spatial and temporal) of oceanographic observations, instrumental errors (XBT) and biases related to the estimation process of global indicators can affect our assessment of the evolution of ocean...

A design for a new underwater video-system to detect and observe suspended particles is presented. Particles are collected and isolated in a rectangular box where they are highly illuminated by a white light plane. The total field of view is determined. The camera, equipped with a remote controlled zoom, can resolve particles sizes ranging from 25 mum to several millimetres. Real-time image analyses are therefore performed. Particle counts and size spectra are calculated and displayed. Total light intensity scattered by the illuminated particles is closely related to the back-scattering values determined by an optical back-scatter sensor. A particle size analyser using diffraction analysis is associated to this video-system on a custom profiler....
