    Campaign GENESIS 2 "Pen Duick/Melilla", the second of three ROV campaigns, will focus on "Pen Duick Escarpment" in the Gulf of Cadiz or on the recently discovered "Melilla mounds" in the South-East Alboran Sea (Mediterranean Sea). The final choice of the study area will depend on the results of the TTR17 cruise with R/V Logachev (June-July 2008) and the R/V Marion Dufresne cruise (June 2008). One of these study areas will be surveyed using multibeam, side-scan sonar and high resolution seismics. Based on this site survey, the ROV Genesis will be deployed to carry out detailed mapping. Also the hydrography and sediment dynamics of the area will be studied with respect to the steering of the present ecosystems. GENESIS 2 takes place in the framework of the European projects HERMES (EC FP6), MiCROSYSTEMS (ESF) and HERMIONE (EC FP7).

    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.

    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 area in between the Audierne and St. Nazaire canyons (Gascogne) along the Armorican margin was one of the areas where the "massifs coralliens" were described for the very first time. Within the framework of the HERMES (EC FP6), MiCROSYSTEMS (ESF) and GeNeSis (FWO) projects, this area will be surveyed using multibeam and high resolution seismics during LEG 1. Based on this site survey, the ROV Genesis will be deployed to carry out detailed mapping of these deep-water "hot-spots". Also the hydrography and sediment dynamics of this area will be studied with respect to the steering of the present ecosystems. LEG 2 will focus on the Galicia bank. This location has been assigned as reference area within the ESF project BIOFUN. In addition to a bathymetric and seismic surveying, also biological sampling and experiments are planned here.

This project takes place in the frame of the research program for earth observation 'STEREO' of the Federal Science Policy.

    The objective of this project is the investigation of the structure and functioning of different CWC successional habitats (living, dead and buried corals), in order to understand the response of the CWC to a changing ocean. Therefore, we identified 4 specific objectives which will allow us to get insight in the distribution of these CWC habitats (objective 1), the responsible environmental drivers (objective 2), the associated (molecular and morphological) biodiversity (objective 3) and the connectivity between distinct CWC habitats at different spatial scales (objective 4). We will concentrate our study on the Bay of Biscay by providing multiple-scale analysis of habitat mapping, environmental characterisation, biodiversity patterns and processes of interconnectivity. However, comparisons will be made through European-US collaboration with other regions at both sides of the Atlantic in order to understand amphi- and trans-Atlantic distribution patterns and processes. This project is part of the 7th EC Framework Programme Hermione (Hotspot Ecosystem Research and Man's Impact On European Seas) (2011-2013).This monitoring project aims to execute a continuous research on the effects of the exploitation of non-living resources of the territorial sea and the continental shelf on the sedimentary movements and the marine environment (Law of 13 June 1969 on the exploration and exploitation of non-living resources of the territorial sea and the continental shelf).

    The GENESIS 1 "Ortegal" cruise will focus, as first one in a series of 3 ROV cruises, on the "Massif Galicien de l'Ouest", located near the "Cabo Ortegal" in the southern part of the Bay of Biscay. These suspected deep-water coral hotspots, earlier described by Le Danois in 1948, will be surveyed using multibeam bathymetry and high resolution seismic profiling. Based on this site survey, ROV Genesis will focus on the detailed visual mapping and sampling of selected sites. Also the hydrography and sediment dynamics of the study area will be studied with respect to their role in steering the present ecosystems. As preparation for the GENESIS 3 cruise, the ROV will also deploy a biological experiment. GENESIS 1 takes place within the framework of the European projects HERMES (EC FP6), MiCROSYSTEMS (ESF) and HERMIONE (EC FP7).

    The goals of this campaign are framed within the objectives of the overall project 'Radial Profunda de Canarias', being the experimental cruise of the proposal. Thus, this cruise will help to: • Determine the structure of the current when it reaches the Canary Islands, of the Outcrop Current and the polar counterflow of slope in its passage through the Canary Archipelago and the African slope, stimating its mass transport, heat and nutrients. • Characterize the different modes of variability of heat and mass transport in easternorth atlantic subtropical gyre and the oucrop in northwest African coast. • Characterize the annual cycle in the physical conditions of the surface layers and mixture to where the seasonal cycle is significant, relating it to the meteorological forcings. • Characterization of changes in water masses, mainly in the North Atlantic Central Water (NACW), in Antarctic Atlantic Intermediate Water (AAIW) in Mediterranean Water (MW), bottom waters of the Canary Basin and the oucrop in northwest African coast, in based on temperature, salinity, nutrients and oxygen. • To characterize the zooplancton and micronecton deep communities. • To charactereze the microbian and heterotrophic communities.
