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. The survey was based on 2 major actions: 1) Artificial mussel stations were placed and recovered along a shoreline between Malaga (Spain) and Sicily (Italy), including Morocco, Algeria and Tunisia. 2) Sediment samples in addition to mussels samples were taken upon the partners' request. This falls under the MEDICIS project.

This was the fourth and last cruise undertaken as part of the NERC-funded consortium project (NE/C512961/1) entitled ECOMAR - Ecosystem of the Mid-Atlantic Ridge at the Sub-Polar Front and Charlie Gibbs Fracture Zone. http://www.oceanlab.abdn.ac.uk/ecomar/index.php ECOMAR forms part of the Census of Marine Life MAR-ECO project which is an international study of life in the northern mid-Atlantic Ocean with scientists from 16 nations participating in research of the waters around the mid-Atlantic Ridge from Iceland to the Azores (http://www.mar-eco.no). Depart: Wednesday, 26 May, St Johns, Newfoundland, Canada. Long term moorings were recovered at four super stations at a bottom depth of 2500m equipped with sediment traps, current meters, ADCP and sensor suites, SE - 49°01.92'N, 27°40.82'W, SW - 48°46.80'N, 28°38.43'W, NW - 53°59.33'N, 36°07.39'W and NE 54°00.05'N 34°10.58'W. Video and still images of the sea floor were obtained during 4 lander deployments and 21 ISIS ROV dives. Faunas samples were taken on 17 of these ROV dives, further samples from 13 successful megacorer casts and 4 baited traps. High definition video sea floor surveys were completed of approximately 50,000 m2 of sea floor. Arrive: Vigo, Spain, Saturday 3 July 2010.

<p style="margin-left:0cm; margin-right:0cm">This multidisciplinary and integrated study comprises geophysical, sedimentological and (bio)geochemical data and aims to present a holistic view on the interaction of both environmental and geological drivers in cold-water coral mound development in the Gulf of Cadiz. In this context, it was fundamental to obtain "samples from the deep" to explore and characterize the biodiversity thought (1) geophysical and video imaging, (2) targeted microbiological profiling, (3) evaluation of present and past oceanic conditions.</p> <p style="margin-left:0cm; margin-right:0cm">Targeted microbiological and biogeochemical transects with long sediment cores were proposed to elicit the 3D spatial architecture and diversity of the microbial mound community and its possible role in slope stabilization. Off-mound cores were also targeted in order to evaluate present and past oceanic conditions by dating of the cored sequences and by reconstruction of water mass and sedimentary dynamics variability for eliciting the time frame of natural biodiversity changes.</p> <p style="margin-left:0cm; margin-right:0cm">The key objective aiming to investigate the microbial diversity and the functional link microbes-metazoans was addressed through biogeochemical approaches (biomarkers), molecular fingerprinting (DGGE, 16S rRNA), fluorescence in situ hybridization (FISH) and laboratory culture. This also includes the analysis of microbial infestation of coral frame builders and fauna-microbe interactions, in general, and the analysis of microbially mediated processes of carbonate precipitation, at various sites and scales: coral mucus, carbonate crusts, mound slopes, mound interior.</p> <p style="margin-left:0cm; margin-right:0cm">The sites targeting was mainly prepared by geophysical surveying (high-resolution sparker seismics, multibeam bathymetry) and ROV imagery, performed by RCMG (Ghent University). Especially the location of all on-mound core sites was determined from interpretation of the ROV Genesis dives during the CADIPOR III campaign of June 2007 on board of R/V Belgica. Additional information was made available through cooperation within past or ongoing European projects such as ESF EuroMARGINS "Moundforce", EC FP5 RTN "EURODOM" and EC FP6 IP "HERMES". Although the MiCROSYSTEMS-MD169 cruise focus was on the Pen Duick Escarpment (PDE), (8 sites, Figures 1 and 2) also other sites such as Conger Cliff (Vernadsky Ridge) and Mercator Mud Volcano were sampled. Special attention was given to the two proposed drill sites for IODP Full proposal 673 "Atlantic Mound Drilling 2: Morocco Margin". A total of five main site locations were identified:<br> 1)The Pen Duick Mounds: Alpha, Beta, Gamma and Epsilon Mounds,<br> 2) The Vernadsky Ridge mounds: Conger Cliff,<br> 3) A depression site at the foot of PDE,<br> 4) Palaeoceanographic reference sites,<br> 5) Mercator Mud Volcano.</p> <p style="margin-left:0cm; margin-right:0cm; text-align:center"><img alt="" src="https://campagnes.flotteoceanographique.fr/campagnes/8200100/images/426.png" style="height:244px; width:500px"></p> <p style="margin-left:0cm; margin-right:0cm"><em>Figure 1: Shipboard map of the SF11 multibeam bathymetry with site tracks.</em></p> <p style="margin-left:0cm; margin-right:0cm">The coring and subsampling strategies used during this campaign were predominantly site-dependent, distinguishing between "on-mound" and "off-mound" sites. Every on-mound site was cored at least two times; one core for geochemistry and microbiology, to be sampled immediately on board, and a second core for sedimentology, palaeoceanography and chronostratigraphy, to be left unopened and stored immediately.

<p style="margin-left:0cm; margin-right:0cm">The Protevs Swot 2018 campaign aimed to explore the South Balearic zone in early spring to observe the small scales of the oceanic mixed layer using high-resolution sampling devices.</p> <p style="margin-left:0cm; margin-right:0cm">The area was chosen because it was positioned below the SWOT satellite's planned swath in its validation/calibration period. In this sense, it is a precursor experiment of experiments for the year 2022 and as such exploratory of the scales that will be observable by this newly designed altimetry satellite.</p> <p style="margin-left:0cm; margin-right:0cm">A particular focus was placed on an anticyclonic structure in the southern Balearic Islands that is systematically detectable by altimetry but which appears to be an artifact.</p> <p style="margin-left:0cm; margin-right:0cm">These samplings were combined with fine analysis of the surface content of small phytoplankton by flow cytometry to study the shaping of the marine landscape by frontal physical processes.</p>

The series of PELMED cruises began in 1993. Their objective is to assess small pelagic resources in the Gulf of Lion, using the echo-integration method and trawling to identify the detections observed. Until 2007, each cruise consisted in systematically prospecting from Port-Vendres to Marseille, along 9 legs set 12 nautical miles apart, perpendicular to the coast, in daytime (6 am to 9 pm), along the entire width of the continental shelf. Acquisition along legs for acoustic prospection covered 440 nautical miles and the catches from trawling to identify the structures encountered led to a complete analysis: number and weight by species, size sampling, otolith samples taken in order to construct size-age keys for sardines, anchovies and hake, updating of biological parameters.

This equipment trials cruise has provided opportunities for test and verification of technology under development at the Proudman Oceanographic Laboratory (POL), the Scottish Association for Marine Science (SAMS) and the National Oceanography Centre, Southampton (NOC,S). This includes equipment developed during the first year of funding under OCEANS 2025 (theme 8). Testing technology in the ocean environment is invaluable in assessing fitness for purpose. Specifically, the cruise tested: A Spar wave buoy (NOC,S) biogeochemical sensors (NOC,S); an UAV system (NOC,S); a video grab system "HyBis" (NOC,S), A benthic Multicore (NOC,S), A benthic lander and associated torroidal Telemetry buoy (POL), and a shallow tow towfish (POL). Testing in Spanish waters (near Tenerife, Gran Canaria and Fuerteventura) has been invaluable. The time on passage has been minimised (the transition from deep to shallow water is less than a days steaming) and the calm conditions to the southwest of the islands in the consistent prevailing north easterly winds have enabled deployment and recovery techniques to be tried and optimised in safety.
