Two profiling floats, equipped with nitrate concentration sensors were deployed in the northwestern Mediterranean from summer 2012 to summer 2013. Satellite ocean color data were extracted to evaluate surface chlorophyll concentration at float locations. Time series of mixed layer depths and nitrate and chlorophyll concentrations were analyzed to characterize the interplay between the physical-chemical and biological dynamics in the area. Deep convection (mixed layer depth &gt; 1000 m) was observed in January–February, although high-nitrate surface concentrations could be already observed in December. Chlorophyll increase is observed since December, although high values were observed only in March. The early nitrate availability in subsurface layers, which...

First success of ProvBIO floats
Provedor de dados: 5
Autores: Le Reste, Serge; Andre, Xavier; Claustre, Herve; D'Ortenzio, Fabrizio; Poteau, Antoine.
The anthropogenic greenhouse effect and the associated temperature rise of the planet represent the main challenging issue for the Earth sciences of the next century. Marine ecosystems are a key component of the Earth system, as they modulate the transfer of greenhouse gases (mainly CO2) to the ocean surface. Moreover, oceanic ecosystems mitigate the effects of anthropogenic carbon injection into the atmosphere, via the so-called “biological pump”. Ocean biogeochemistry is hence confronted to a major challenge: the determination of the extent and efficiency of the climatic feedback of the carbon “biological pump” within the context of climate change.  A new type of float, the “ProvBio”, has been developed jointly by Ifremer and the French company KANNAD,...

Autores: Coppola, L.; Prieur, L.; Taupier-letage, I.; Estournel, C.; Testor, P.; Lefevre, D.; Belamari, S.; Le Reste, Serge; Taillandier, V.
During the winter 2013, an intense observation and monitoring was performed in the north-western Mediterranean Sea to study deep water formation process that drives thermohaline circulation and biogeochemical processes (HYMEX SOP2 and DEWEX projects). To observe intensively and continuously the impact of deep convection on oxygen (O2) ventilation, an observation strategy was based on the enhancement of the Argo-O2 floats to monitor the offshore dense water formation area (DWF) in the Gulf of Lion prior to and at the end of the convective period (December 2012 to April 2013). The intense O2 measurements performed through shipborne CTD casts and Argo-O2 floats deployment revealed an O2 inventory rapidly impacted by mixed layer (ML) deepening on the month...

In February 1994, during the SAMBA 1 cruise, 9 CTD casts were done and 22 subsurface floats (20 MARVOR, 1 VCM, 1 ALFOS) launched near 800 dbar in the Brazil basin, within the framework of the SAMBA Experiment. SAMBA (SubAntartic Motions in the Brazil bAsin), is a component of the WOCE float program, and aims at describing the absolute general circulation of the Antarctic Intermediate Water around 800 m depth in the Brazil basin. MARVOR and ALFOS floats cycle every 2 months between thier nominal depth and surface to transmit data via the ARGOS system and were programmed for 30 cycles, i.e. a total life of 5 years. THE VCM float, on the other hand is a one shot RAFOS-type float which was programmed for a 1.5 year mission at depth. This report presents the...

Argos-3 Satellite Communication System: Implementation on the Arvor Oceanographic Profiling Floats
Provedor de dados: 5
Autores: Andre, Xavier; Moreau, Bertrand; Le Reste, Serge.
The scientific community observes the ocean for applications in the fields of oceanography and climate research. In order to recover in situ data, more than 3,000 profiling floats are operated in the framework of the Argo Program. Each float performs cycles between the sea surface and a depth of 2,000 meters. Scientific data are gathered while the float is travelling upward from the depths of the oceans, and are then transmitted via a satellite communication system at the end of each cycle. During its time at the surface, mainly dedicated to transmissions, the float is vulnerable and subject to drift, which limits its use in many studies. Moreover, transmission times are becoming longer due to a trend towards high resolution or multi-sensor profiles....

In the past two decades, the Argo Program has collected, processed, and distributed over two million vertical profiles of temperature and salinity from the upper two kilometers of the global ocean. A similar number of subsurface velocity observations near 1,000 dbar have also been collected. This paper recounts the history of the global Argo Program, from its aspiration arising out of the World Ocean Circulation Experiment, to the development and implementation of its instrumentation and telecommunication systems, and the various technical problems encountered. We describe the Argo data system and its quality control procedures, and the gradual changes in the vertical resolution and spatial coverage of Argo data from 1999 to 2019. The accuracies of the...

The international Argo program, consisting of a global array of more than 3000 free-drifting profiling floats, has now been monitoring the upper 2000 meters of the ocean for several years. One of its main proposed evolutions is to be able to reach the deeper ocean in order to better observe and understand the key role of the deep ocean in the climate system. For this purpose, Ifremer has designed the new “Deep-Arvor” profiling float: it extends the current operational depth down to 4000 meters, and measures temperature and salinity for up to 150 cycles with CTD pumping continuously and 200 cycles in spot sampling mode. High resolution profiles (up to 2000 points) can be transmitted and data are delivered in near real time according to Argo requirements....

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).

The Biogeochemical-Argo program (BGC-Argo) is a new profiling-float-based, ocean wide, and distributed ocean monitoring program which is tightly linked to, and has benefited significantly from, the Argo program. The community has recommended for BGC-Argo to measure six additional properties in addition to pressure, temperature and salinity measured by Argo, to include oxygen, pH, nitrate, downwelling light, chlorophyll fluorescence and the optical backscattering coefficient. The purpose of this addition is to enable the monitoring of ocean biogeochemistry and health, and in particular, monitor major processes such as ocean deoxygenation, acidification and warming and their effect on phytoplankton, the main source of energy of marine ecosystems.

Salinity is the essential parameter for ocean dynamics studies. Its definition and using in the equations used to calculate the thermodynamic properties of seawater, were revised in 2010, opening the possibility of new sensors developments. In this context, NOSS (NKE Optical Salinity Sensor) has emerged as one of the first underwater instrument for in situ refractive index measurement in the past years open up the scope of possibilities to access to density parameter. This achievement is the fruit of the cooperation between several institutions and the fruit of several years of developments and trials. NOSS sensor is designed to be deployed in coastal environment and open-ocean waters up to 2000m, especially on profiling floats of the Argo network.

The international array of profiling floats known as Argo is a major component of the global ocean- and climate-observing system. In 2010, the NAOS (Novel Argo Observing System) project was selected as part of France’s Equipex “Investissement d’Avenir” program. The objectives of NAOS were to consolidate the French contribution to the Argo core mission (global temperature and salinity measurements down to 2,000 m) as well as to develop the future generation of French Argo profiling floats and prepare the next phase of the Argo program with an extension to the deep ocean (Deep-Argo), biogeochemistry (BGC-Argo) and polar seas. This paper summarizes the main technological advances and at-sea validations carried out as part of NAOS: development of a deep (4,000...
