This experiment was promoted by the Jerico European project (JOINT EUROPEAN RESEARCH INFRASTRUCTURE NETWORK FOR COASTAL OBSERVATORIES), in the framework of a collaborative work proposed by the workpackage 4, “Maintenance and Calibration”, and the “Forum for Coastal Technologies”.
The purpose of this experiment was to compare the calibration methods used by different institutes or firms within an inter-laboratory comparison (ILC). In terms of metrology, this comparison will allow the laboratories to assess their...
JERICO. Report after the Strategic workshop # 1 (Heraklion) - Farcy, Patrick; Puillat, Ingrid; Durand, Dominique; Beaume, Nolwenn; Pichard, Maelle
One of the main JERICO objectives is to establish a strategy for the future of the coastal observation. In other words, firstly JERICO has both to perform the state of the art with regards to European coastal observation systems and to help harmonizing technologies and sharing knowledge. Then according to the results of this first stage, the project will deliver a strategic plan to step forward. As a starting point, a roadmap was written in deliverable D1.2 “Rationale and Definitions for a Common Strategy” to give a framework to the project participants and inform about intentions. The following step in...
JERICO. First FCT Activities Report. D#1.6 - Puillat, Ingrid; Aoustin, Yannick; Monbet, Philippe; Nolan, Glenn
This report describes the different actions carried out within the Forum for Coastal Technology framework. FCT’s actions were implemented to better encourage collaboration between public stakeholders (scientists, managers, executives, ..) and private companies to ensure a common and coherent approach of the technical developments for operational oceanographic systems. In that sense, the two main FCT actions for this first JERICO’s year were dedicated to (1) enquire about needs and expectations from companies manufacturing oceanographic instrumentations and sensors companies and (2) the organisation of the first FCT workshop at the Sea Tech Week event in Brest (France, october 2012).
JERICO. Interim Periodic Activity Report. 2nd - Farcy, Patrick; Puillat, Ingrid; Beaume, Nolwenn
The main objectives of the 2nd period were to finalise the “best practices handbooks” for glider (with GROOM), ferrybox and fixed platform. The project organises also workshops on JRA (Villefranche in October 2013) for presenting the mid-term results of WP10. JERICO also launched the second and third calls for Trans National Access.
The mid-term review has been pass successfully in june 2013. The second general Assembly was held in Oslo on the 5th and 6th of May 2014. A dedicated JERICO website has been upgraded. All the submitted deliverables (except the consortium agreement) are available on this site: www.jerico-fp7.eu
Tank test related instrumentation and best practice - Ohana, Jeremy; Bourdier, Sylvain
Marine energy devices are still at development stage and many models are being tested in the different hydrodynamics facilities. Improving the measurements quality of these tests by exchanging between the technical staff of the Marinet partners is one of the Work Package 4 objectives.
This report is an experience feedback from Marinet tests. It was written mostly from Ifremer experience and aim to present the instrumentation techniques needed to carry out quality tank testing.
The first part reviews the typical physical parameters to be measured, gives a short description of the sensors working principle and examples of implementations. The flow...
Euro-Argo. Global Ocean Observing Infrastructure. Float technology analysis. Del. n°4.2.1 - Le Reste, Serge; Gould, John
In this report, we review the status of present-day float technology and consider its likely evolution over the coming years in respect of float design, lifetime, cost, new sensors, improved telecommunications etc. Float manufacturers and their products are first analyzed and the competitiveness of European providers assessed. New and emerging requirements for improved capabilities and performances (communications, lifetime) in particular for marginal seas and additional or improved sensors (e.g. O2, sea ice, density, sea surface temperature and sea surface salinity, bio-optical, plankton), are also detailed. Bio-geochemical and bio-optical sensors are currently under development. Combining such sensors with the mature profiling...
Ostreid herpesvirus type 1 replication and host response in adult Pacific oysters, Crassostrea gigas - Segarra, Amelie; Baillon, Laury; Tourbiez, Delphine; Benabdelmouna, Abdellah; Faury, Nicole; Bourgougnon, Nathalie; Renault, Tristan
Since 2008, massive mortality outbreaks associated with OsHV-1 detection have been reported in Crassostrea gigas spat and juveniles in several countries. Nevertheless, adult oysters do not demonstrate mortality in the field related to OsHV-1 detection and were thus assumed to be more resistant to viral infection. Determining how virus and adult oyster interact is a major goal in understanding why mortality events are not reported among adult Pacific oysters. Dual transcriptomics of virus-host interactions were explored by real-time PCR in adult oysters after a virus injection. Thirty-nine viral genes and five host genes including MyD88, IFI44, IkB2, IAP and Gly...
A new potentially toxic Azadinium species (Dinophyceae) from the Mediterranean Sea, A. dexteroporum sp. nov. - Percopo, Isabella; Siano, Raffaele; Rossi, Rachele; Soprano, Vittorio; Sarno, Diana; Zingone, Adriana
A new photosynthetic planktonic marine dinoflagellate, Azadinium dexteroporum sp. nov., is described from the Gulf of Naples (South Tyrrhenian Sea, Mediterranean Sea). The plate formula of the species, Po, cp, X, 4, 3a, 6, 6C, 5?S, 6'" and 2, is typical for this recently described genus. Azadinium dexteroporum is the smallest rep-resentative of the genus (8.5m average length, 6.2m average width) and shares the presence of a small antapical spine with the type species A.spinosum and with A.polongum. However, it differs from all other Azadinium species for the markedly asymmetrical Po plate and the position of the ventral pore, which...
Fatigue behaviour of natural rubber in marine environment: comparison between air and sea water - Le Gac, Pierre-yves; Arhant, Mael; Davies, Peter; Muhr, Alan
Natural rubber has been successfully used in a marine environment for many years. However, most applications involve low dynamic loadings. Due to the emergence of marine energy recovery, wave and tidal energy converters are being developed. In some such devices, rubbers are subjected to severe cyclic loadings, very different from their previous use in air or water. Such rubbers must therefore be qualified for long-term use in sea water with high fatigue loading. This paper presents a study using a new fatigue machine that allows the fatigue behaviour of rubber in sea water to be compared to that in air....
Maternally Inherited npm2 mRNA Is Crucial for Egg Developmental Competence in Zebrafish - Bouleau, Aurelien; Desvignes, Thomas; Traverso, Juan Martin; Nguyen, Thaovi; Chesnel, Franck; Fauvel, Christian; Bobe, Julien
The molecular mechanisms underlying and determining egg developmental competence remain poorly understood in vertebrates. Nucleoplasmin (Npm2) is one of the few known maternal effect genes in mammals, but this maternal effect has never been demonstrated in nonmammalian species. A link between developmental competence and the abundance of npm2 maternal mRNA in the egg was previously established using a teleost fish model for egg quality. The importance of maternal npm2 mRNA for egg developmental competence remains unknown in any vertebrate species. In the present study, we aimed to characterize the contribution of npm2 maternal mRNA to early developmental success in zebrafish...
Individual growth monitoring of European sea bass larvae by image analysis and microsatellite genotyping - De Verdal, Hugues; Vandeputte, Marc; Pepey, Elodie; Vidal, Marie-odile; Chatain, Beatrice
The aims of the present study were to develop non-lethal methods to identify individual fish larvae and post-larvae before tagging and accurately follow their growth characteristics. European sea bass (Dicentrarchus labrax) was used as a model species at four different ages ranging from 71 to 100 days post fertilization (dpf).
Two different methods were tested for non-lethal tissue sampling from each larva for DNA analysis: 1) using a sterile absorbent paper to sample mucus and/or epithelial cells by rubbing the fish skin and 2) fin-clip of the bottom part of the caudal fin. Whatever the age of the larvae, the genotyping...
How do demersal fishing fleets interact with aggregate extraction in a congested sea? - Marchal, Paul; Desprez, Michel; Vermard, Youen; Tidd, Alex
The effects of the aggregate extraction intensity and the distance to extraction sites on the distribution of fishing effort were investigated for a broad selection of French and English demersal fleets operating in the Eastern English Channel. The most prominent result was that most fleets fishing near to aggregate extraction sites were not deterred by extraction activities. The fishing effort of dredgers and potters could be greater adjacent to marine aggregates sites than elsewhere, and also positively correlated to extraction intensity with a lag of 0–9 months. The distribution of fishing effort of French netters remained consistent over the study...
Marine Litter Distribution and Density in European Seas, from the Shelves to Deep Basins - Pham, Christopher K.; Ramirez-llodra, Eva; Alt, Claudia H. S.; Amaro, Teresa; Bergmann, Melanie; Canals, Miquel; Company, Joan B.; Davies, Jaime; Duineveld, Gerard; Galgani, Francois; Howell, Kerry; Huvenne, Veerle A. I.; Isidro, Eduardo; Jones, Daniel O. B.; Lastras, Galderic; Morato, Telmo; Gomes-pereira, Jose Nuno; Purser, Autun; Stewart, Heather; Tojeira, Ines; Tubau, Xavier; Van Rooij, David; Tyler, Paul A.
Anthropogenic litter is present in all marine habitats, from beaches to the most remote points in the oceans. On the seafloor, marine litter, particularly plastic, can accumulate in high densities with deleterious consequences for its inhabitants. Yet, because of the high cost involved with sampling the seafloor, no large-scale assessment of distribution patterns was available to date. Here, we present data on litter distribution and density collected during 588 video and trawl surveys across 32 sites in European waters. We found litter to be present in the deepest areas and at locations as remote from land as the Charlie-Gibbs Fracture...
Global habitat preferences of commercially valuable tuna - Arrizabalaga, Haritz; Dufour, Florence; Kell, Laurence; Merino, Gorka; Ibaibarriaga, Leire; Chust, Guillem; Irigoien, Xabier; Santiago, Josu; Murua, Hilario; Fraile, Igaratza; Chifflet, Marina; Goikoetxea, Nerea; Sagarminaga, Yolanda; Aumont, Olivier; Bopp, Laurent; Herrera, Miguel; Fromentin, Jean-marc; Bonhomeau, Sylvain
In spite of its pivotal role in future implementations of the Ecosystem Approach to Fisheries Management, current knowledge about tuna habitat preferences remains fragmented and heterogeneous, because it relies mainly on regional or local studies that have used a variety of approaches making them difficult to combine. Therefore in this study we analyse data from six tuna species in the Pacific, Atlantic and Indian Oceans in order to provide a global, comparative perspective of habitat preferences. These data are longline catch per unit effort from 1958 to2007 for albacore, Atlantic bluefin, southern bluefin, bigeye, yellowfin and skipjack tunas. Both quotient...
The effect of discards and survival rate on the Maximum Sustainable Yield estimation based on landings or catches maximisation: Application to the nephrops fishery in the Bay of Biscay - Guillen, Jordi; Macher, Claire; Merzéréaud, Mathieu; Fifas, Spyros; Guyader, Olivier
MSY objectives are being adopted as major fisheries management targets worldwide. However, in fisheries where discards account for an important share of the catches, the yield, effort, and biomass at MSY can be significantly different when accounting or not for discards and thus when, basing the yield estimations on landings or catches. Also whether accounting for a certain survival rate, of discards can lead to different MSY targets estimates. Hence, both decisions have important, implications on catch and effort reduction recommendations, and consequently on the quota, calculations for fisheries managed by quotas. Results from the Bay of Biscay nephrops fishery...
A framework for evaluating management plans comprehensively - Trenkel, Verena; Rochet, Marie-joelle; Rice, Jake C
We present a framework for evaluating fisheries management plans comprehensively, both rebuilding plans and others. The framework includes a first rapid appraisal of the likelihood that the plan will result in management meeting its objectives, and guides subsequent quantitative analyses of potential weaknesses in the proposed plan. The framework includes four steps: (i) evaluating if a set of management objectives, if achieved, would result in a sustainable fishery, (ii) using qualitative analysis of a bio-economic model to evaluate whether the set of stock management tactics might be capable of achieving the specified fisheries objectives, (iii) using empirical criteria derived from...
Observations of large infragravity wave runup at Banneg Island, France - Sheremet, Alex; Staples, Tracy; Ardhuin, Fabrice; Suanez, Serge; Fichaut, Bernard
On Banneg Island, France, very high water-level events (6.5 m above the astronomical tide) have been observed on the western cliff, exposed to large swells from the North Atlantic. The analysis of hydrodynamic measurements collected during the storm of 10 February 2009 shows unusually high (over 2 m) infragravity wave runup events. By comparing runup observations to measurements in approximately 7 m of water and numerical simulations with a simplified nonlinear model, two distinct infragravity bands may be identified: an 80 s infragravity wave, produced by nonlinear shoaling of the storm swell; and a 300 s wave, trapped on the intertidal...
