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.

Assessment of chemical contamination in coastal water masses (Spain, Morocco, Tunisia, Sicily canal), using artificial stations of mussels. The MYTILOS1 cruise aimed to utilize the RINBIO network methodology around the western Mediterranean, in the northern part of the NW Basin. Experiments run in the French Mediterranean since 1996 by IFREMER were to be extended to Southern Mediterranean coasts, i.e. Spanish, Moroccan, Algerian and Tunisian coasts, as well as the Sicily Canal in Italy, on the basis of a standardized protocol. The data from MYTILOS2 cruise will supplement those obtained in 2004 and 2005 during the RINBIOC1 and MYTILOS1 cruises by including the coasts of North Africa, Southern Spain and the island of Pantelleria. In addition, the results will be used to complement the chemical contamination budget drawn up in the framework of the European Water Framework Directive's implementation. This falls under the 'MEDICIS' project.

FWO MINIMOUND Project: Using Cold-water coral mini-mounds as analogue for giant mound growth: assessment of environmental drivers and anthropogenic impact Cold-water corals (CWC) are found along the entire north-eastern Atlantic Margin from Norway to the Gulf of Cadiz. In the Porcupine Seabight, these coral reefs (mainly Lophelia pertusa and Madrepora oculata) accumulate into large mounds of up to 250m high (e.g. Challenger Mound), which have been well studied over the past two decades (Roberts et al., 2006). The detailed mechanism of the start-up phase of such large CWC mounds is however not yet fully understood. Therefore, it is essential to study analogues of these stages that are not well recorded in larger mounds. The FWO MINIMOUND project (2013-2016) aims to investigate the initiation, growth and demise of small CWC mounds and to determine the role of climatic and hydrocarbon-seepage related processes as well as anthropogenic impact. This high-resolution multidisciplinary study will focus on three minimound provinces along the Biscay continental margin: (1) the Explorer and Dangeard Canyons on the Celtic Margin (Fig. 1; Stewart et al., 2013), (2) the Guilvinec Canyon on the Armorican Margin (De Mol et al., 2011) and (3) the Upper Ferrol Canyon on the Cantabrian Margin (Fig. 1). These minimounds are fossil (9.7 ka BP) and occur at relative shallow depth on the interface between the Eastern North Atlantic Central Water (ENACW) and the Mediterranean Outflow Water (MOW). Contrastingly, most present-day living CWC reef habitats dwell in the deeper MOW depth range, relying on the density and dynamics of this water mass for their food supply.   The objectives of the project are threefold: (1) the establishment of a chronostratigraphic framework and the reconstruction of palaeoceanographic changes over the last 15.000 years in order to determine the impact of glacial to interglacial climate change on the ENACW-MOW interface and the CWC habitats (Frank et al., 2011); (2) the minimound province at the Upper Ferrol Canyon shows a close association with hydrocarbon-seepage (pockmarks) which allows to assess the role of hydrocarbon related processes in CWC mound formation; (3) the potential impact of anthropogenic fisheries activities will be investigated. These objectives will be tackled through a coupled geophysical, sedimentological and integrative approach, including the palaeoceanographic and biogeochemical study of sediment cores in cooperation with the BGS (UK), LSCE (Gif-sur-Yvette, France), IFREMER (France), IGME (Spain) and IEO (Spain). This Belgica2015/15 cruise is the second campaign of the project and it aims to sample both on-mound as off-mound sites by means of a 4.5 m vibrocorer (Supplied by the British Geological Survey, BGS). The target site are located on the upper slopes of the Ferrol Canyon (Cantabrian margin, Spanish EEZ) and the Guilvinec Canyon (Armorican margin, French EEZ) between 200 and 600 m water depth. In each sector, a minimum of 3 days of activities will be scheduled. In case of bad weather on 1 sector, the program will be revised towards the other sector. With respect to the size of these mounds, the coring location of the vibrocorer will be steered by means of am IXSEA USBL GAPS system. During night-time, the seafloor will be visually characterized using a small and light-weight camera dropframe (University of Plymouth).

The objective of cruise JC103 was to service the moorings of the RAPID 26°N project that are deployed to monitor the Atlantic Meridional Overturning Circulation. For each mooring instruments were recovered, data were downloaded and instruments were redeployed. A number of CTDs were made to calibrate the instruments from the moorings. During passage from port of Spain to Nassau trial CTDs were completed in the waters of the Turks and Caicos Islands. After departing Nassau on 29th April work commenced on the western boundary sub-array comprising of moorings WBADCP, WBAL, WB1, WB2, WB2l, WB2h, WB4 and WB4L. The ship returned to Nassau on 6th May to disembark one person before sailing east once again. The final mooring of the wester sub-array was serviced on 8th May before continuing east to the mid-Atlantic Ridge (MAR) sub-array. Work on the MAR sub-array commenced on 13th May at mooring MAR0. The other moorings in this sub-array were MAR1, MAR1L, MAR2, MAR3 and MAR3L were all completed by 18th May. On the following day the NOG mooring was deployed and as the ship transited to the astern sub-array the first of 5 Argo floats was deployed on 21st May. The eastern boundary sub-array starts at EB1, which was serviced on 23rd May. Following this moorings at EB1L, EBHi, EBH1, EBH2, EBh3,EBh4 and EBH4L in the following days up until 31st May. A number of CTDs were completed form 31st may to 2nd June.

This project was a hydrographic section at latitude 24°N, with physical, chemical and biological measurements. The section was a complete section from continent to continent from North America (Caribbean) to Africa (off the coast of the Western Sahara). The section started and ended in 200 metres water depth, at the edge of the continental shelf. This was a contribution to the international CLIVAR/Carbon repeat hydrography program (http://ioc3.unesco.org/ioccp/Hydrography/New_GlobalMap.html). Climate change will be studied by comparing the new data with historical measurements. Ocean heat transport plays a major role in the coupled ocean-atmosphere climate system. We will study the present-day circulation by calculating the heat and freshwater transported by the ocean across the 24°N latitude. The ocean western boundary current system, in this case the Gulf Stream flowing through the Florida Strait, plays a crucial role in the oceanic heat transport. Therefore a crossing of the Florida Strait will be carried out to establish the status of this important ocean feature. All data arising from the cruise will be lodged and made available via the British Oceanographic Data Centre (BODC), UK.
