    <p>Sea recovery of all components of a stratospheric balloon: balloon envelope, parachutes, and gondolas. Test of new gamma detectors and characterization of solar panels for the Strateole project. There has been no work done at sea after balloon fly. The balloon flight took place. The climb path was consistent with the expected. However the ceiling track was a little south and a little slower than expected. The ball has arrived above the sea but too south. Down a bit low, he found the westerly winds that brought him back to earth. Separating late flight and recovery have made campaigning in the Basque country.</p>

    Core sampling on the mudflat of the Basque continental shelf. This falls under the Aquitaine / Euskadi project.

    Optical (Rrs) and hydrological measurements to determine and quantify particles in suspension and dissolved organic matter at the surface of the water using satellite images. The measurements taken along the Basque country coast are used to validate the algorithms developed using data from the BATEL-1 mission. An additional objective is to supply in-situ optical and hydrological data for the doctoral theses of C. Petus and S.Novoa. The oceanographic mission took place in 2 parts due to a mechanical incident aboard RV Côte de la Manche. The cruise is part of the inter-regional Aquitaine-Euskadi (OOSSEA) programme, CIFRE contract.

    The BATEL-1 cruise was conducted from 4 to 14 June 2007 by the University of Bordeaux-1 (EPOC laboratory). The main objective was to obtain a database of optical and geochemical data in order to create algorithms to quantify the suspended particles and dissolved substances for the interpretation of MODIS, SPOT, ASTER and FORMOSAT-2 satellite images. The end purpose is to identify coastal water composition from satellite images. The second aim was to monitor the Adour river's turbidity plume during this period. In addition, measurements were taken to analyze the heavy metals, stratification of water masses (CTD) and for intercomparison of two fluorimeters. These measurements are currently being used by Ms. Petus (Thesis, Cifre grant). The cruise fell under the interregional Aquitaine-Euskadi programme.

    -Validation of surface salinity measurements using drifting buoys. Three models of drifting buoys (17 buoys in all) were deployed in the Bay of Biscay on 2 April (R/V Thalassa trip) and on 2-3 May (COSMOS1 aboard Côtes de la Manche). This involved passing close to the buoys, taking samples, TSG measurements and CTD hauls to validate the data. Two sections taken by CTD probe in front structure eddy (for the CONGAS programme). Retrieval of a prototype PROVOR-CTS3 float deployed in May by the Côte d'Aquitaine vessel. 9 CTD sensors to be attached to elephant seals were tested (mounted on SBE25 CTD during profiles). This falls under the COSMOS project, headed by J. Boutin and G. Reverdin.
