MOOSE T00_29 (EGO himilcon glider) deployment (Mediterranean Sea - Western basin)

[Lien vers la fiche source] The proposed research is based on the monitoring of the long term evolution of the North Western Mediterranean Sea with glider repeat-sections carried out in the framework of the ALLENVI/INSU/ SOERE MOOSE (http://moose-network.fr), INSU/MISTRALS (http://www.mistrals-home.org), and EU FP7 PERSEUS (http://www.perseus-net.eu). The objective is to monitor the oceanographic variability (physical and biogeochemical) of the north western Mediterranean Sea, over a continuum of spatial and temporal scales. Two cross-basin repeat-sections with a repeat rate of about 10-20 days allow to monitor the main circulation features (Northern Current, North Balearic Front, Western Corsica Current) on a regular basis, as well as major processes such as winter intermediate and deep water formations and vernal blooms. The gliders regularly visit MOOSE moorings for cross-calibration purposes and to explore the variability around these moorings. i) T00 is a repeat-section between Nice and Calvi passing by the MOOSE mooring DYFAMED located in the central Ligurian Sea ii) T02 is a repeat-section between Marseille and Menorca passing by the MOOSE mooring LION located in the center of the deep convection area The following parameters are provided : - Practical salinity - Sea temperature in-situ ITS-90 scale - Electrical conductivity - Sea water pressure, equals 0 at sea-level
Mineralogical and Nd-Sr isotopic data from the Red Sea and the Gulf of Aden sediments

[Lien vers la fiche source] Cores MD92-1002 and MD92-1008 were retrieved during the MD73 REDSED campaign of R/V Marion Dufresne in 1992 and are located in the western Gulf of Aden and southern Red Sea, respectively. The aim was originally to identify sediment sources thanks to the use of radiogenic isotopes. The sedimentary record in both cores presented large magnetic susceptibility peaks, which had been measured by Bouilloux et al. (2013), and these variations could have been caused either by source changes or by postdepositional processes. Nd and Sr isotopes vary depending upon rock types, and magnetic measurements can reflect lithological variations. Therefore the relationship between these parameters, can allow us to discriminate between source-driven changes and diagenetic processes that could induce variations in the magnetic signal. The studied basins are situated in a region influenced by the Asian and African monsoons, which had temporal variations. It is also one of the major regions of dust deposition, being near the Saharan and the Arabian deserts. Source determination of sediments in the basins can help us understand modern and past atmospheric pathways and relate them to climate variations. Using sediment cores that cover at least 20 ka enables the study of the last climatic cycle, i.e. the Last Glacial Maximum (LGM), the deglaciation and the present interglacial period. To further constrain the type of sources of the sediments being carried to the Red Sea and Gulf of Aden basins we also performed DRX analyses to measure the relative proportions of minerals in the bulk fraction and in the clay fraction. The clay fraction is a minor part in these sediments, however clay minerals are derived from weathering of the continents and they allow us to understand past environmental conditions. The combination of all these different tracers can help us decipher the mechanisms of sediment transport and link them to environmental variations during the Quaternary. X-ray diffraction (XRD) analyses were performed using a PANalytical X'Pert Pro Diffractometer (GEOPS Laboratory, Université Paris-Sud). Errors in mineral percentages were estimated to be around 1-2%. Sr and Nd isotope analyses were carried out on 22 carbonate-free samples from each core at a sampling resolution of around 40 cm. Nd and Sr isotopic compositions were analyzed using a Thermo Finnigan Neptune Multiple Collector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS) at the GEE Laboratory, IPGP (Paris, France). The results are published in Rojas et al. (2019) https://doi.org/10.1016/j.quascirev.2019.02.033.
Marine aggregates: production tonnage and fleet size; business estimates; benchmark on main producing countries

[Lien vers la fiche source] Marine aggregates are included in a larger "aggregate extraction" sector in the French classification of economic activities. Key figures are therefore estimated, based on (1) extraction and employment data mainly sourced from the industry, (2) on INSEE's business statistics related to the larger aggregate extraction sector. International figures are limited to extracted volume and tonnage and are sourced from ICES, the only international organisation collecting data at international level.

ELISA (1997-1998) mesoscale survey in the Algerian sub-basin (Western Mediterranean): hydrological data set of the cruises ELISA-1 (summer 1997) and ELISA-2 (fall 1997)

[Lien vers la fiche source] The Eddies and Leddies Interdisciplinary Study in the Algerian sub-basin (ELISA) experiment (1997–1998) was a multidisciplinary and multiplatform experiment designed to study the anticyclonic Algerian Eddies (AEs) generated by the instability of the Algerian Current, and their influence on the general circulation and biological phenomena. The data collected confirmed for instance the eastward path of LIW along the Algerian slope, and showed that these anticyclones correspond to the richer areas in spring. Following the daily analysis of satellite thermal images to track the AEs, the sampling scheme was adapted in real time, using transects with CTD casts every ~10km. So that the data are strongly "biased" toward describing (moving) eddies at high resolution: they are likely to be unadequate for a few purposes. The ELISA hydrological data sets have been obtained during the four cruises ELISA-1 to 4, from summer 1997 to summer 1998. This data set includes the ELISA-1 cruise (summer 1997) with 199 CTD profiles on 121 stations plus associated water bottles samples, and the ELISA-2 cruise (fall 1997) with 6 CTD profiles. Data sets are delivered in both netcdf and ODV formats.

Haul duration experimental data set (0 & 30 minutes hauls)

[Lien vers la fiche source] In 2003 two experiments were carried out in the Bay of Biscay to compare catch numbers obtained in standard research 30-min hauls with those from 0-min hauls to determine the so called end effect. The end effect in trawl catches is defined as the proportion of the fish catch taken during shooting and hauling of the net, a period excluded from what is nominally referred to as haul duration. In 0-hauls the trawl was hauled as soon as the trawl geometry stabilized on the seabed. The trawl used was a beam trawl rigged as twin trawl. Overall 24 hauls were carried out, six 30-min and 18 0-min hauls. Average catch ratios (0-min/30-min hauls) ranged from 0.05 (s.d. 0.06) for sole to 0.34 (s.d. 0.64) for hake.
Civil marine research effort in main French research organisations: data and estimates

[Lien vers la fiche source] Marine research covers several specialities, most often developed within international programmes, in keeping with the scale of the problems for ocean and environmental status. The activity involves a small number of public organisations, some of which work in several fields. - Ifremer, university and CNRS (National Centre for Scientific Research) oceanography laboratories, the SHOM French Navy hydrographic and oceanographic service, the IRD Research Institute for Development and the IPEV Paul-Emile-Victor Polar Research Institute are the main scientific organisations in public-sector ocean and marine research. - Earth-observation satellites provide an additional spatial component for oceanographic research. They are financed by CNES National Centre for Space Studies, generally in the framework of bilateral or multilateral co-operation. - The other principal research bodies involved in ocean studies are: Météo-France (French Meteorological office), INRA (National Agronomy Research Institute), CIRAD Agricultural Research Centre for Development, BRGM Office for Geological and Mining Research. - Genavir, economic interest group, operates a large part of the ocean research fleet on its own and other partners' behalf, including the research vessels of Ifremer and IRD and the submarine equipment of Ifremer. The assessment of marine research effort requires a detailed assessment of the staff working on marine science in research organisations. Most of these are not exclusively dedicated to marine science; estimates are thus necessary to value staff costs. Data source: marine research organisations
Long-term and high-resolution time series datasets of vent species abundance from the Grotto hydrothermal edifice (Main Endeavour Field, Juan de Fuca Ridge)

[Lien vers la fiche source] Focused on vent ecology, the TEMPO-mini ecological observatory module is deployed on the active Grotto hydrothermal edifice (Main Endeavour Field, Juan de Fuca Ridge), selected as a target site for the deep-sea cabled observatory Ocean Networks Canada. To study long-term temporal dynamics of vent communities, the camera was programmed to record 20-min video sequences six times a day (02.00, 06.00, 10.00, 14.00, 18.00 and 22.00 UTC) with three zoom levels per sequence corresponding to ‘large’, ‘medium’ and ‘fine’ views. The camera was focused on a Ridgeia piscesae tubeworm assemblage harbouring a dense community of associated fauna. Temporal variation in the observed abundances of four visible taxa (Ammotheidae pycnogonids, Polynoidae polychaetes, Buccinidae gastropods and Zoarcidae eelpouts) was quantified using the large and medium views (see Figure). To avoid ‘observer bias’ among consecutive measurements, video sequences were analysed in random order. The first observation strategy had a fixed daily observation time set at 10.00 UTC encompassing two years from 20 June 2013 to 20 June 2015. The second observation strategy was designed to identify seasonal components of macrofaunal and environmental variability. All six observations (observation frequency of TEMPO-mini) were analysed during one summer (June 2014) and three winters (November 2014, December 2014 and January 2015) months. These specific time windows were selected to minimize the amount of missing data generated by temporary shortcomings of the observatory and to maximize the presence of high-quality video imagery. Details on these observation methods and analyses conducted on a part of these datasets are published in Lelièvre et al. 2017 (DOI:10.1098/rspb.2016.2123).
Map of the active fault system across the oceanic lithosphere of the Mozambique Channel, from the data of the PTOLEMEE (2014), PAMELA-MOZ02 (2014) and PAMELA-MOZ04 (2015) marine expeditions

[Lien vers la fiche source] Seismic reflection and multibeam echosounder data were acquired in the Mozambique Channel in 2014 and 2015 during the PTOLEMEE, PAMELA-MOZ02 and -MOZ04 marine surveys onboard the RV Atalante and Pourquoi Pas? These data revealed that an active fault system is deforming the oceanic lithosphere of the Mozambique Basin which has developed during Jurassic-Cretaceous times. The correlation between the fault system and the arrangement of the associated earthquake epicenters suggests that this tectonically active zone directly connects northward with the southern part of the eastern branch of East African Rift System which corresponds to the seismically active graben system bounding the northern part of the Davie ridge. The fault zone extends southwestward of the Mozambique Ridge along the same trend as the Agulhas-Falkland transform fault zone. The general organization of the fault zone shows the characteristics of an extensional system north of the Mozambique Channel (north of the Europa Island) and a right-lateral transtensional system with coeval normal faults and strike-slip faults south-west of Europa. This tectonic activity is associated with volcanic activity since at least Late Miocene times. Our findings highlight that the eastern branch of the East African Rift System is extending largely toward the south, not only in continental domains but also through the oceanic lithosphere of the Mozambique basin. This fault zone is participating to the complex plate boundary between the African main continent (Nubia Plate) and Madagascar (Somalia Plate).Digital data (.csv) are available as an attached file.
IAOOS winter SIMBA data during N-ICE 2015 North of Svalbard

[Lien vers la fiche source] Two ice mass balance instruments (part of IAOOS7 and IAOOS8 platforms) deployed near 83°N on the same ice floe, documented the evolution of snow and ice conditions in the Arctic Ocean north of Svalbard in Jan-Mar 2015. Frequent profiles of temperature (every 3 hours) and temperature change after 30s and 120s heating (once a day) were recorded. The ratio of the temperature changes after heating provides a proxy for thermal diffusivity. Both instruments documented flooding and snow-ice formation. Flooding was clearly detectable in the simultaneous changes in thermal diffusivity proxy, increased temperature, and heat propagation through the underlying ice. Slush then progressively transformed into snow-ice. Flooding resulted from two different processes; i) after storm-induced break-up of snow-loaded floes for IAOOS8 and ii) after loss of buoyancy due to basal ice melt for IAOOS7. The instrument on IAOOS7 documented basal sea-ice melt over warm Atlantic waters and ocean-to-ice heat flux peaked at up to 400 Wm-2 in winter.
Morphological traits measured for 89 fish species sampled in the Mediterranean Sea during MEDITS scientific surveys

[Lien vers la fiche source] The data come from organisms and pictures collected during the MEDITS annual bottom trawl surveys conducted between 2011 and 2013 (Bertrand et al. 2002). MEDITS surveys cover the continental shelf (10 m to 200 m depth) and the upper part of the continental slope (200 m to 800 m) on the Mediterranean. A total of 1511 individuals from 85 fish species were collected from seven Mediterranean areas (South Adriatic Sea, Sardinia, Gulf of Lions, around Cyprus, Mallorca, Tyrrhenian Sea, and North West Ionian Sea). A set of 14 morphological traits related to the habitat and the diet of the species were measured in the field and on pictures using the ImageJ software (version 1.47, http://imagej.nih.gov/ij/) (see Granger et al. 2015 and Brind'Amour et al. submitted for details) (Figure 1). Replicats of measures vary between 1 (e.g. Scorpaena loppei) to 53 (e.g. Serranus hepatus) according to fish species. Twelve of the chosen traits consist in continuous biological characteristics measured on each individual (measured in cm). The two remaining traits are categorical and determined at the species level.
Gironde Estuary Mouth MEasurement Stations (GEMMES)

[Lien vers la fiche source] In the framework of the ANR AMORAD project, the METEOR cruises (Grasso, 2017) aimed at deploying the ‘Gironde Estuary Mouth MEasurement Stations’ (GEMMES) to measure hydrodynamics and sediment dynamics at the mouth of the Gironde Estuary and on the West Gironde Mud Patch (SW France, Bay of Biscay). Measurements were carried out between November 2016 and December 2017: i) from a buoy station around 20-m water depth (GEMMES-20), collecting sub-surface data of temperature, salinity and turbidity; and ii) a benthic station around 40-m water depth (GEMMES-40), collecting data of current velocity and turbidity. Bottom and surface water samples were regularly collected to calibrate turbidity measurements to SPM concentrations.

Observations for Synaphobranchus kaupii from bait experiments carried out in the Bay of Biscay in 2002 using ROV Victor 6000

[Lien vers la fiche source] The data come from bait experiments that were carried out at three study sites (Meriadzek Terrace, terrace located between the canyon of Belle Île and the canyon of St Nazaire referred to as St Nazaire Terrace, and Belle Île Canyon) on the continental slope of the Bay of Biscay during the VITAL cruise in late August and early September 2002 using the ROV Victor 6000. A full description of the experiments and results can be found in Trenkel and Lorance (2011). The depth range 1100 – 1500 m was investigated in all sites by perpendicular strip transects starting from the deepest point and moving up slope (see full description in Trenkel et al 2004). Bait experiments were carried out at all three sites at regular intervals (every 12 hours) along the transects. Two types of bait were used, a standardised aquaculture paste and cod fillets (only on St Nazaire Terrace). The paste was made of fish farming food pellets mixed with sea water (480 g per liter). Sardine oil was added (3 cm3 per liter) to increase the smell of the bait. The bait was filled into identical bottles (~4 cm diameter opening, 15.5 cm high). At the beginning of the experiment the ROV opened the bottle, put it onto the ground and retreated a few meters perpendicular to the current to observe fish arrival. After it was judged that no more individuals were going to arrive, the ROV shook the bottle to create a new plume and continued observations. In one experiment the bottle was shaken a second time. Video tapes were analysed in the laboratory after the cruise for Kaup's arrowtooth eel (Synaphobranchus kaupii). For each individual arriving, the time and direction of arrival, the initial behaviour and the reaction to the bait were noted. Initial behaviour was categorised by the position in the water column: near the bottom (<1 body length) or higher up in the water column (>1 body length) and the locomotion type: drifting or moving with current (“with current”), swimming against current or swimming perpendicular to the current. Reaction to the bait was categorised as not interested, attracted, touching bait bottle or eating bait. When possible the speed of the first individual arriving swimming against the current was estimated. Using the size of the bait bottle as a yard stick the time taken for swimming a certain distance (1 cm on the video screen) was recorded on two occasions and used to calculate the average arrival speed. At the deepest point sampled at each site (1460-1550m), an autonomous lander equipped with a current meter was deployed for three days. Data from these sensors were recorded every minute to every two minutes. A temperature probe was carried by the ROV.
