<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.

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.

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.

The main testable hypothesis of the proposed work is: Atmospheric inputs control rates of primary production and microbial diversity in oceanic waters where nutrients are limiting. The objectives of the project are to: 1. Obtain an improved temporal and spatial estimate of atmospheric dust inputs to the tropical N Atlantic through collections on a dedicated SOLAS process cruise. 2. Obtain an improved estimate of the seawater dissolution of N, P, Fe and Zn species from aerosol dust. 3. Determine the impact of atmospheric dust derived micronutrients on microbial community production and species diversity in the surface microlayer and underlying waters. In addition, researchers from the Archer/Geider group were on-board. The overall aim of their research was to determine the extent to which the photoprotective roles of DMSP and QAs influence their production rates in marine surface waters and hence, the production of their volatile breakdown products. The cruise objectives for this work were to: 1. relate DMSP and QAC concentrations to plankton community structure, light regime, photoinhibition, xanthophyll cycle and MAA accumulation in varying oceanic provinces and over diel cycles. 2. determine the potential for photoinhibition and DMSP/GBT turnover in natural phytoplankton in contrasting oceanic provinces. The cruise departed Tenerife on February 5, 2008, and we have conducted regular stations (typically 2 per day) along the cruise track. The track took us into the oligotrophic Atlantic waters, productive Cape Verde waters, and tropical waters with very high nitrogen fixation (judged initially from the Trichodesmium concentrations). The various researchers and groups have also started a range of biological experiments at different sites along the cruise track. We have encountered a major dust event in week 2, and then from week 3 of the cruise we encountered large amounts of dust. We have visited the TENATSO time series site near the Cape Verdes and have undertaken an extensive set of measurements there. We have collected the atmospheric dust for elemental analyses (at UEA and NOCS), and also to produce leachates which are used on board for biological experiments. We have undertaken sampling of the water column to analyse for dissolved and particulate metals, nutrients, dissolved organic matter, amino acids, hemes, thiols and phytochelatin synthase expression. In addition, nitrogen fixation measurements were undertaken, in tandem with nifh gene sampling. Nitrate uptake experiments have been conducted. Furthermore, bacterial phosphate uptake experiments have been undertaken using addition of collected dust. Halocarbon and DMS gas measurements have been conducted during the cruise. In addition, experiments have been undertaken by the Archer/Geider group on effects of high sun light exposure on DMS and GBT production. The cruise has been very successful with a minimum of lost time.
