“…Several excellent field data sets have been collected since the 1970's from a few beaches. The ECORS-Truc Vert campaign was designed to fill gaps in previous data sets [1]. In this framework, numerous instruments were set up in the ECORS-Truc Vert site to measure hydrodynamics processes, sediment characteristics and transport, and morphodynamics of the beach over many scales under energetic swell and macro-tidal conditions : for instance, video systems on the embryonic dune, pressure sensors lines above and under the sand, current sensors into the water.…”

Ocean color measurements onboard a jet ski: consistency for calval exercise of high-resolution satellite imagery?

An original data set has been acquired on the 5 th of April 2008 during the international field experiment ECORS-Truc Vert 2008 (SW France) in the nearshore zone over a complex bathymetry and in moderate turbid waters (SPM <10 mg/l). This data set synchronizes in-situ reflectance measurements onboard a jet-ski, bathymetric surveys and a Formosat-2 high-resolution satellite acquisition. The jet-ski provides an interesting mean to gather optical data in shallow waters and in environments hard to sample with traditional coastal ships. An experimental device has been implemented on the jet-ski, equipped with two TRIOS RAMSES sensors which measure simultaneous atmospheric downwelling irradiances E d and in-water upwelling radiances L u in the 350-950nm range. Water samples have also been collected at different stages of the jet-ski trajectory (3-25m water depth) in order to assess the concentrations of the ocean constituents (SPM and Chl-a). In the current study we present a methodology to validate FORMOSAT-2 high-resolution ocean color data using "jetski" reflectance measurements, which first require a detailed analysis. The reflectance spectra measurements are shown to be consistent : (i) they are typical of the presence of mineral particles with light absorption at short wavelengths ; (ii) their shape and magnitude depend on the depth and the water type (turbidity) ; (iii) some of them, especially in low turbid waters, are similar to other reflectance spectra measured northward from a ship (Gironde mouth). Thus, the use of "jet-ski" ocean color measurements appears to be adequate for remote sensing calval activities in shallow case-2 waters.

The shoreline along sandy beaches is located at a unique position on the earth's surface where marine and terrestrial processes converge. The swash zone distinguishes the landward-most reach of wave action. Field observations from this shallow and highly energetic region reveal that individual waves regularly deposit or remove hundreds of kilograms of sand per meter width of beach. Such high rates of sand movement represent several centimeters of bedlevel change and far exceed the underlying pace of beach evolution. Relatively large morphological changes caused by single swashes might suggest that very rapid beach erosion or accretion is a common occurrence. The contrasting reality shown by these new observations is that beaches generally exhibit a state of dynamic equilibrium.
