Assessment of chemical contamination in coastal water masses (Spain, France, Italy), using artificial stations of mussels and passive sensors. The MYTILOS 1 cruise aimed to use the RINBIO network methodology around the western Mediterranean. Experiments done in the French Mediterranean since 1996 by IFREMER will be extended to Spanish and Italian Mediterranean coasts on the basis of a standardized protocol. The data will supplement those obtained in 2004 during the RINBIOC1 cruise by including the islands of the western basin, the south of Spain and Italy. In addition, the results will be used to complement the chemical contamination budget made in the framework of the European Water Framework Directive's implementation. The survey was based on 3 major actions: 1) Artificial mussel bed stations were placed and recovered along a shoreline between Malaga (Spain) and Rome (Italy), including the Balearic Islands, Sardinia and Sicily. 2) Gellyfish-type "passive" sensor stations were deployed along with some of the artificial mussel bed stations. 3) A study was run on the site of Livorno, taking bio-integrators, Posidonia and sediment samples to assess chemical contamination levels on 3 different matrices in the framework of the MONIQUA programme. This falls under the MEDICIS project.

CD170 was a collaborative cruise with the Knorr cruise KN182_2. The latter cruise was conducted between 2 May 2005 and 26 May 2005. These cruises were completed as part of the UK Natural Environment Research Council (NERC) funded RAPID Programme and the US National Science Federation (NSF) funded MOCHA Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5 degrees North. The primary purpose of both cruises was to service the 26.5 degrees North mooring array deployed in 2004 during RRS Discovery cruises D277 and D278. These cruises are the first annual refurbishment of this array.

The SCANS-II project aims at estimating the abundance of small cetaceans inhabiting shelf waters of the Atlantic margin, the North Sea and adjacent waters. Different methods will be used; ship-based monitoring is one of these. Data on abundance are essential to assess the impact of bycatch and other threats, and as input to management actions to ensure the favourable conservation status of these species. The project will develop a management framework to use such data. This will be centred on relatively simple but spatially explicit dynamic models tested by simulation to ensure robustness. An essential part of this long-term management is a robust cost-effective means of monitoring abundance between major SCANS-type surveys; the project will develop and test potential methods, and recommend a suite of monitoring protocols.The "BEL-COLOUR" aims at improving the theoretical basis and software tools for applications of suspended matter and chlorophyll-based satellite data products in coastal waters. In addition to algorithm work and image processing BEL-COLOUR will participate in sea borne cruises for the purposes of calibration of algorithms and for validation of the end products. The project "BEL-COLOUR", funded by the <a href="http://www.belspo.be">Federal Science Policy</a>, within the programme for Earth Observation "STEREO" - Study and management of Coastal Regions.

-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.

Beautemps-Beaupré cruise.

The objective of the cruise was to improve our understanding of biochemical processes in the near-surface and microlayer of the ocean. We examine gradients in major nutrient concentrations and cycling, production and consumption of key biogases and variability in biological communities between micro-layer, near -surface and deeper water, and between productive and oligotrophic waters along a transect from offshore oligotrophic to coastal upwelling waters off western Spain and Portugal. We also aimed to examine the influence of gradients in physical, biological and photochemical processes at or near the surface micro-layer on the transport of heat and bio-gases across the air-sea interface. Using near-real time satellite imagery of ocean colour in combination with continuous underway measurements of sea surface temperature and chlorophyll fluorescence we identified a suitable oligotrophic site ~25nm off the coast just north of the spain/Portugal border, and reached it on 21 st June and commenced scientific work. We then worked our way inshore via 4 more stations to an upwelling site where science work was concluded on 6th July. The vessel then returned to Falmouth, arriving on 9th July.

This falls under the MYTILOS project.
