A BGC-Argo Guide: Planning, Deployment, Data Handling and Usage ArchiMer
Bittig, Henry C.; Maurer, Tanya L.; Plant, Joshua N.; Schmechtig, Catherine; Wong, Annie P. S.; Claustre, Hervé; Trull, Thomas W.; Udaya Bhaskar, T. V. S.; Boss, Emmanuel; Dall’olmo, Giorgio; Organelli, Emanuele; Poteau, Antoine; Johnson, Kenneth S.; Hanstein, Craig; Leymarie, Edouard; Le Reste, Serge; Riser, Stephen C.; Rupan, A. Rick; Taillandier, Vincent; Thierry, Virginie; Xing, Xiaogang.
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. Here we...

Argos-3 Satellite Communication System: Implementation on the Arvor Oceanographic Profiling Floats ArchiMer
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....

ARVOR communication improvements for marginal seas applications ArchiMer
Le Reste, Serge; Andre, Xavier.
New requirements have appeared in the last few years for profiling floats and the ARVOR float is being made to meet these new requests. The two main requirements are less surface time and the ability to modify mission parameters after deployment to monitor specific events.. As a solution, the Arvor has been fitted with Iridium and Argos-3

Deep-Arvor: a CTD & DO profiling float for Argo ArchiMer
Le Reste, Serge; Dutreuil, Vincent; Andre, Xavier; Trautmann, Coralie; Bescond, Tanguy.
The first prototype of Deep-Arvor was deployed this summer. Deep-Arvor is designed to achieve more than 150 profiles from 3500 meters depth, with CTD continuously pumping and oxygen measurements. High resolution profiles are transmitted by the Iridium satellite system. Deep-Arvor maintains the self-ballasting feature of Provor/Arvor and the easy deployment of Arvor thanks to its light weight.

“Deep-Arvor”: A new profiling float to extend the Argo observations down to 4000m depth. ArchiMer
Le Reste, Serge; Dutreuil, Vincent; Andre, Xavier; Thierry, Virginie; Renaut, Corentin; Le Traon, Pierre-yves; Maze, Guillaume.
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....

Deep-Arvor floats (4000m) : first results and future plans ArchiMer
Thierry, Virginie; Mercier, Herle; Maze, Guillaume; Le Reste, Serge; Dutreuil, Vincent; Andre, Xavier; Lenault, Yannick.
The Deep-Arvor float is an Argo float designed to achieve more than 150 profiles at 4000m depth. It is equipped with a SBE41CP CTD. Oxygen measurements are in option (4330 optode). Two 3500 dbar models were deployed in 2012 and 2013. Two 4000 m (4120 db) industrials prototypes were deployed in 2014. We expect to deploy twelve 4000 m floats in 2015 and 2016. Results at sea of the first 4 Deep-Arvor are presented.

Deep-Arvor: The results of the first industrial prototype deployment ArchiMer
Dutreuil, Vincent; Le Reste, Serge; Thierry, Virginie; Andre, Xavier; Lenault, Yannick; Renaut, Corentin; Brault, Patrice; Sagot, Jerome; David, Arnaud.
Deep-Arvor was designed by Ifremer to achieve more than 150 profiles from 4,000 meters depth, with CTD continuously pumping and oxygen measurements. After the validation of two first models at the sea, the industrialization has been entrusted to NKE. The first constructed prototypes of Deep-Arvor have been deployed successfully in May 2014. Thanks to its light weight, Deep-Arvor maintains the self-ballasting feature of Provor/Arvor and the easy deployment of Arvor. High resolution profiles are transmitted by the Iridium satellite system.

In the last ten years, a productive collaboration has grown between the Laboratoire d’Océanographie de Villefranche (LOV), NKE and IFREMER to implement biogeochemical sensors on profiling floats. A first project (2003) was dedicated to the design of the so-called ProvBio floats (models A and B) that consisted of a PROVOR-CTS3 float instrumented with three new optical sensors: a Wetlabs transmissometer (C-Rover), a 3-wavelength Satlantic radiometer (OCR-503) and an “ECO3” Wetlabs sensor, measuring chlorophyll-a fluorescence, colored dissolved organic matter and particle backscattering coefficients (see First Success of ProvBio floats, Coriolis Letter n°5). Then, the integration of biogeochemical sensors continued in the framework of ProNuts project (2009,...

Le Reste, Serge.
This document is the synthesis of the results of WP2 work, obtained from the five experiments that were conducted with the floats deployed at sea. Task 2.1 concerns the comparison of two oxygen sensors, Task 2.2 has to test new deep floats, Task 2.3 evaluates bio-geochemical floats, Task 2.4 is dedicated to satellite transmission performance assessment andtask 2.5 concerns Arctic floats. It is the deliverable D2.61 identified in the description of work DA-1, in the table WT 2, which was initially due by the end of June 2015 (T0+30), but which was postponed to October 2015 (T0+34) (see minutes of 5thsteering committee meeting), T0 being the 1st of January 2013.

Euro-Argo. Global Ocean Observing Infrastructure. Float technology analysis. Del. n°4.2.1 ArchiMer
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 float technology should...

First success of ProvBIO floats ArchiMer
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,...
