A real-time dive on active hydrothermal vents ArchiMer
Sarrazin, Jozee; Sarradin, Pierre-marie; Buffier, Erick; Christophe, Alain; Clodic, Guillaume; Desbruyeres, Damien; Fouquet, Yves; Gouillou, Michel; Jannez, Michel; Le Fur, Yann; Le Rest, Jacques; Lecornu, Fabrice; Lefort, Olivier; Lux, Stephanie; Millet, Brigitte; Guillemet, Pascal.
The Momareto cruise was held from August 6 to September 6, 2006 on the new French oceanographic vessel Pourquoi pas? The ROV Victor 6000 visited three vent fields, ranging from 850m to 2300m, on the Mid-Atlantic Ridge. The scientific objective of the cruise was to study the spatial and temporal dynamics of hydrothermal communities colonizing these active vent sites. Aside scientific and technological objectives, one of the major goals of this cruise was to share the excitement of our science with the public. For this, the results of the project were shared through different media. The most challenging and exciting communication event remains the real-time transmission of images acquired by the ROV Victor at 1700m depth to a 250 person audience on land.

Ecological model of the Bay of Biscay and English Channel shelf for Environmental Status assessment Part 1: Nutrients, phytoplankton and oxygen ArchiMer
Menesguen, Alain; Dussauze, Morgan; Dumas, Franck; Thouvenin, Benedicte; Garnier, Valerie; Lecornu, Fabrice; Repecaud, Michel.
European directives (Water Framework Directive - WFD and Marine Strategy Framework Directive - MSFD) require a regular survey of several descriptors of the Environmental Status of coastal waters of the North-east Atlantic Ocean. Especially for the MSFD, which may concern large continental shelf areas where measurements are scarce, realistic ecological models can help assessing the Environmental Status. The ECO-MARS3D model of the pelagic ecosystem of the Bay of Biscay and English Channel continental shelf (NE Atlantic) has been developed for these applied purposes and validated against various types of historic data. This first paper deals with the basic biogeochemical version, which contains inorganic nutrients (NH4, NO3, PO4, Si(OH)4), three...

General Introduction: PREVIMER, a French pre-operational coastal ocean forecasting capability. ArchiMer
Dumas, Franck; Pineau-guillou, Lucia; Lecornu, Fabrice; Le Roux, Jean-francois; Le Squere, Bruno.
Pre-operational system PREVIMER provides with coastal observations and forecasts along French coasts: currents, waves, sea levels, temperature, salinity, primary production and turbidity. These marine environmental data come from in situ observations, satellite images, and numerical models. They are centralized and archived in PREVIMER databases, then published on website (real time and historical data), and freely available to users, private companies as well as public administrations. This paper describes in details PREVIMER components and users.

MENOR: a high-resolution (1.2 km) modeling of the North-Western Mediterranean Sea routinely run by the PREVIMER operational forecast system ArchiMer
Garnier, Valerie; Pairaud, Ivane; Nicolle, Amandine; Alekseenko, Elena; Baklouti, Melika; Thouvenin, Benedicte; Lecornu, Fabrice; Garreau, Pierre.
IFREMER has encouraged for over 15 years the oceanographic modeling of sea waters all around the metropolitan French coasts in order to facilitate environmental coastal studies. In that context, the North-Western Mediterranean Sea confi guration (MENOR: 1.2 km – 60 vertical levels) has been introduced in the framework of Previmer operational forecasting system (http://www.previmer.org/en). This article gives an insight into the operational applications and scientific research using this MENOR configuration.

Operational modelling of nutrients and phytoplancton in the bay of biscay and english channel ArchiMer
Menesguen, Alain; Dussauze, Morgan; Lecornu, Fabrice; Dumas, Franck; Thouvenin, Benedicte.
Nitrate loadings to the French coastal waters of the Bay of Biscay and the English Channel have increased from 5 to 10 times during the four last decades, due to runoff on intensively fertilized agricultural watersheds. Eutrophication of this coastal zone is now a recurrent problem, with wellknown direct impacts (Ulva “green tides” on beaches, excessive phytoplanktonic blooms responsible for “coloured waters” and bottom hypoxia events offshore), but also indirect enhancement of the toxicity of some phytoplankton species, caused for instance by increased N:Si ratio in the coastal sea. In order to better guide the decision makers about nutrient loading reduction, Ifremer uses the so-called ECO-MARS3D biogeochemicalhydrodynamical model to simulate the present...

PREVIMER: A coastal operational oceanography system coupled to the Copernicus Marine Service ArchiMer
Lecornu, Fabrice; Pineau-guillou, Lucia; Dumas, Franck; Le Traon, Pierre-yves; Gohin, Francis; Menesguen, Alain.
Our coastal zones are subject to increasing anthropogenic pressure. Monitoring systems are required to protect them, prevent or mitigate risks and to ensure a sustainable management of their resources. PREVIMER is a partnership between Ifremer (French Research Institute for Exploitation of the Sea), SHOM (French Hydrographic Office) and several major French institutions (www.previmer.org). It provides coastal observations, analyses and 4 days forecasts for the French coasts of the English Channel, Atlantic Ocean and Mediterranean Sea: currents, water levels, waves, temperature, salinity, turbidity, nutrients and plankton concentrations. The service includes information based on in situ, satellite observations and numerical simulations. PREVIMER products...

To design a prototype for an Integrated Ocean Observing System (IOOS), at least three components are mandatory: a modeling platform, an in situ observing system and a structure to collect and to disseminate the information (e.g. database, website). The PREVIMER project followed this approach and in order to sustain model applications, PREVIMER has developed, funded and organized part of in situ observing networks in the Bay of Biscay and the Channel. For a comprehensive system, focus was addressed on fi xed platforms (MAREL MOLIT, MAREL Iroise, Island network and D4 for sediment dynamics), ships of opportunity (RECOPESCA program and FerryBoxes), and coastal profi lers (ARVOR-C/Cm). Each system is briefl y described and examples of scientifi c results...

PREVIMER: Improvement of surge, sea level and currents modelling ArchiMer
Pineau-guillou, Lucia; Dumas, Franck; Theetten, Sebastien; Ardhuin, Fabrice; Lecornu, Fabrice; Le Roux, Jean-francois; Idier, Deborah; Muller, Heloise; Pedreros, Rodrigo.
The pre-operational system PREVIMER provides coastal observations and forecasts along French coasts. It provides, among other variables, currents, sea levels, surges and waves. This paper describes the development and validation of a high temporal (15 minutes) and spatial (250 m) resolution modeling system, based on MARS hydrodynamic model (Lazure and Dumas 2008), along the Atlantic and English Channel coasts. Models benefi t from experiments developed during the PREVIMER project by: (1) taking better into account wind and wave actions (improving surface drag coeffi cient parameterization), (2) taking into account a better meteorological forcing (improving spatial and temporal meteorological resolution). These high resolution models have been integrated in...

Prévision opérationnelle des niveaux de la mer, surcotes et décotes sur les côtes de la Manche et de l’Atlantique ArchiMer
Pineau-guillou, Lucia; Theetten, Sebastien; Dumas, Franck; Lecornu, Fabrice; Idier, Deborah.
Le système pré-opérationnel PREVIMER fournit des observations et des prévisions côtières sur les trois façades métropolitaines Manche, Atlantique et Méditerranée. Il fournit en particulier les prévisions de courants, niveaux de la mer, surcotes et décotes et vagues. L’objectif de l’étude est de mettre en place un système de modélisation des ondes longues (2DH) haute résolution (une centaine de mètres) sur l’ensemble des côtes métropolitaines. Les expériences menées dans le cadre de PREVIMER ont mis en évidence l’importance d’une meilleure prise en compte de l’action du vent et des vagues - par l’amélioration de la paramétrisation du coefficient de traînée en surface - et du wave set-up. Ainsi, ces modèles à haute-résolution intègrent ces dernières...
