The objectives of the BELMER project are: - to validate the MERIS water products for Belgian coastal waters and neighbouring French, UK and Dutch waters - to provide a quantitative statement of product accuracy and recommendations for improvements in the scientific algorithms, where appropriate. In particular the problems reported by the MERIS validation and user communities of turbid water atmospheric correction, case 2 water chlorophyll retrieval, adjacency effects (straylight), moderate sunglint, spatio-temporal variability of specific inherent optical properties and bottom reflectance will be addressed. This project is funded by the "PROgramme for the Development of scientific Experiments" (PRODEX) of the European Space Agency (ESA).

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.

Overall objectives in the EU GO project are to assess the promising potential of seismic imaging for physical oceanography, in view of its combination of fine resolution and coverage unmatched by conventional oceanographic measurements. D318 was to provide the means of assessment by obtaining a unique, comprehensive, oceanographic and seismic dataset at the same time and place. Specific objectives for R.R.S. Discovery cruise 318a were to deploy four ADCP moorings, three adjacent temperature-logger moorings and STABLE, in an L-shape array in 750-1000m depth east of Portimao Canyon, carrying out adjacent CTD stations, deploy two OBH moorings, carry out seismic sections using the Ifremer high-frequency air-guns and streamer, accompanied by regular XBT and less frequent XCTD casts. In addition underway data was logged including ship-borne ADCP, surface temperature and salinity, meteorology, gravity and magnetics (to test new NERC magnetometers).

D318 was to provide the means of assessment by obtaining a unique comprehensive oceanographic and seismic dataset at the same time and place. Specific objectives for R.R.S. Discovery cruise 318b were to (i) recover four ADCP moorings, three adjacent temperature-logger moorings and STABLE, from 750-1000m depth east of Portimao Canyon (ii) perform deep water CTD casts (iii) carry out seismic sections using the NMF supplied Bolt airgun and streamer, accompanied by regular XBT and less frequent XCTD casts, iv) work with MV Poseidon to test novel seismic data acquistion strategies. In addition underway data was logged including ship-borne ADCP, surface temperature and salinity, meteorology, gravity and magnetics (to test new NERC magnetometers).

The three key objectives of our original proposal were to test: 1. The hypothesis that mantle upwelling and melting is focused at the centres of slow spreading ridge segments and transposed by sub-horizontal flow away from there. 2. The hypothesis that plate accretion and separation mechanisms are fundamentally different in 'magma-starved' areas. 3. Mechanisms of detachment faulting and extensional strain localisation in the lower crust and upper mantle. We proposed to achieve these objectives by detailed surveying and sampling across an extensive region of magma-poor seafloor spreading around Fifteen Twenty Fracture Zone (FTFZ), coupled with microstructural, geochemical and palaeomagnetic analyses. TOBI deep-towed sidescan and magnetic data were to be obtained both to inform the choice of sampling sites and to aid in structural, lithological and geodynamic interpretations. We spent 29 days on the Mid-Atlantic Ridge (MAR) in the vicinity of 13 to 15N. We collected multibeam ship-based bathymetry, gravity and magnetic data and TOBI sidescan, magnetic and water-column data from a total area of about 8,000 km2. We recovered samples from 47 drill and dredge stations throughout the area, in support of the objectives.
