Toward a Comprehensive and Integrated Strategy of the European Marine Research Infrastructures for Ocean Observations

Research Infrastructures (RIs) are large-scale facilities encompassing instruments, resources, data and services used by the scientific community to conduct high-level research in their respective fields. The development and integration of marine environmental RIs as European Research Vessel Operators [ERVO] (2020) is the response of the European Commission (EC) to global marine challenges through research, technological development and innovation. These infrastructures (EMSO ERIC, Euro-Argo ERIC, ICOS-ERIC Marine, LifeWatch ERIC, and EMBRC-ERIC) include specialized vessels, fixed-point monitoring systems, Lagrangian floats, test facilities, genomics observatories, bio-sensing, and Virtual Research Environments (VREs), among others. Marine ecosystems are vital for life on Earth. Global climate change is progressing rapidly, and geo-hazards, such as earthquakes, volcanic eruptions, and tsunamis, cause large losses of human life and have massive worldwide socio-economic impacts. Enhancing our marine environmental monitoring and prediction capabilities will increase our ability to respond adequately to major challenges and efficiently. Collaboration among European marine RIs aligns with and has contributed to the OceanObs’19 Conference statement and the objectives of the UN Decade of Ocean Science for Sustainable Development (2021–2030). This collaboration actively participates and supports concrete actions to increase the quality and quantity of more integrated and sustained observations in the ocean worldwide. From an innovation perspective, the next decade will increasingly count on marine RIs to support the development of new technologies and their validation in the field, increasing market uptake and produce a shift in observing capabilities and strategies.Peer reviewe

OceanGliders Oxygen SOP

The live version of this SOP is on the Ocean Gliders community in GITHUB. The home repository of this publication is in the Ocean Best Practices Repository. This standard operating procedure (SOP) document for dissolved oxygen (DO) aims to guide the user through the steps necessary to collect good quality dissolved oxygen data using ocean gliders for both real time and post deployment data streams

Uncoupled transport of chlorofluorocarbons and anthropogenic carbon in the subpolar North Atlantic

Chlorofluorocarbon (CFC) 11 and 12 transports across the transoceanic World Ocean Circulation Experiment (WOCE) A25 section in the subpolarNorthAtlantic are derived from an inverse model using hydrographic and ADCP data (Lherminier et al., 2007). CFC and anthropogeniccarbon (CANT) advective transports contrary to expected are uncoupled: CANT is transported northeastwards (82±39 kmol s−1) mainly within the overturning circulation, while CFC-11 and CFC-12 are transported southwestwards (−24±4 and −11±2 mol s−1, respectively) as part of the large-scale horizontal circulation. The main reason for this uncoupled behaviour is the complex CFC vs. CANT relation in the ocean, which stems from the contrasting temperature relation for both tracers: more CANT dissolves in warmer waters with a low Revelle factor, while CFC’s solubility is higher in cold waters. These results point to CANT and CFC having different routes of uptake, accumulation and transport within the ocean, and hence: CANTtransport would be more sensitive to changes in the overturning circulation strength, while CFC to changes in the East Greenland Current and Labrador Sea Water formation in the Irminger Sea. Additionally, CANT and CFCs would have different sensitivities to circulation and climate changes derived from global warming as the slowdown of the overturning circulation, increase stratification due to warming and changes in wind stress.Este trabajo fue financiado por MOREBIS (CTM2008-01554-E).Peer reviewe

Les courants de l'Atlantique Nord - le projet OVIDE.

The OVIDE project studies the variability of the north Atlantic subbpolar gyre circulation based on repeated hydrography and current measurements, satellite observations, diagnostic and prognostic models. Here, we present an analysis of volume and heat transports between Greenland and Portugal from the 2002 OVIDE data. The results are compared to a previous analysis based on 1997 data (4x project). We focus on the thermohaline circulation. The thermohaline circulation, deep western boundary current and heat flux variability are correlated

Nous présentons ici une analyse des transports de volume et de chaleur entre le Groenland et le Portugal à partir d’observations réalisées dans le cadre d’OVIDE en 2002 ainsi qu’une comparaison avec des résultats avec des données de 1997 (projet 4x). Nous nous focalisons sur la circulation thermohaline et ses composantes. Les amplitudes de la circulation thermohaline, du transport de chaleur et du courant profond de bord ouest varient dans le même sens.Mercier Herlé, Deniaud-Lherminier Pascale, Gourcuff Claire.
