    The RAS (Remote Auto Sampler) mooring deployed during the SOCLIM cruise, in October 2016, has been recovered!

    Juila Uitz

    In last October, a RAS (Remote Auto Sampler) mooring had been deployed in the central part of the Kerguelen Plateau, where the waters are naturally enriched in iron leading to enhanced phytoplankton biomass compared to surrounding waters...

    Four SOCLIM team members, Stephane Blain, Ingrid Obernosterer, Olivier Crispi and Xavier Morin, are currently onboard the vessel Marion Dufresne and have just recovered the RAS. The samples and the in-situ data collected by this mooring over spring and summer will be brought back to the lab for analysis and interpretation. They will reveal the seasonal dynamics of the biogeochemical properties in the surface layer of this special oceanic system.

    Monaco ocean week - a week of interaction and mobilisation for ocean conservation

    Carolyn Scheurle

    From 30 March to 4 April, more than 30 events have been organized in various symbolic venues of the Principality of Monaco. These events brought together local and international experts, the scientific community, the voluntary sector and public authorities to share their experiences and reflect on marine conservation and blue economy sustainable development ...

    Workshops, symposiums, seminars, exhibitions, documentary film screenings and public awareness events were held in venues such as the Oceanographic Museum, the Monaco Yacht Club, the International Hydrographic Organization’s head office and Stars’N’Bars. Within this context, the co-principal investigator of the SOCLIM project Hervé Claustre, his collaborator Jean-Pierre Gattuso and the “mon ocean & moi” team proposed several events to reach out to the wider public:

    • 1/ In a conference-style and focusing on the Southern Ocean, Hervé Claustre talked about ongoing research and robotic observations of the ocean in the context of climate change.

    • 2/ Jean-Pierre Gattuso spoke about climate change and the oceans and particularly addressed in his oral presentation possible consequences and solutions.

    • 3/ The “mon ocean & moi” team proposed a complementary communication and hands-on activities centered on ocean observation by profiling floats and ocean acidification.

    Southern Ocean plankton from the SOCLIM cruise

    Mathieu Rembauville

    Samples for microplankton diversity taken during the SOCLIM cruise are being analysed under a microscope. ...

    The cruise described a latitudinal transect from the warm subtropical waters to the cold Antarctic waters, providing the opportunity to observe an important diversity of size and shapes. Species are enumerated, identified, and images are acquired before numerous morphometric measurements are performed on the micrographs. The biovolume of plankton communities can be derived from these measurements combined with shape-specific equations....

    This classical, time-consuming technique remains the only one able to provide plankton biovolume with a sufficient taxonomic resolution. It is then compared to the optical signal reported by modern optical tools that recorded the water optical signature during the SOCLIM cruise. Understanding the optical signatures of different plankton communities will be of great interest in order to interpret the numerous optical data reported by the floats deployed in the Southern Ocean.

    Final floats checking before departure to La Réunion Island

    Christophe Penkerc'h

    On June the 10th, 8 SOCLIM floats were ready to embark on a very long trip...

    It was a long process for the team of engineers from the Laboratoire d’Océanographie de Villefranche (Edouard Leymarie, Antoine Poteau and Christophe Penkerc’h) to prepare the 8 floats up to their departure from Villefranche via Brest on their way to La Réunion. The preparation started a year ago, when NKE, the manufacturer, delivered the floats. First we tested the floats in the deep pool of Ifremer (Brest) in order to check the navigation. Then, we shipped them to the Villefranche Lab for additional tests and preparation.

    Two kinds of floats have been prepared:


    • Six Bio-Argo floats to which Antoine added an oxygen sensor to the initial payload. Then he programed the mission of the floats for the Southern Ocean. It takes an expert eye to set a dozen of parameters without reading the documentation!

    • Two ProIce floats, similar to Bio-Argo but with ice detection capability.

    For these, we started by doing the internal cabling between the electronic boards and the connections to the sensors. This was a thorough, time-consuming work! Then we attached all the sensors to the floats, checking at every step that the communication was working properly. The following step was to adjust the weight of the floats so they have perfect buoyancy. Finally, after we programmed the floats mission, we ran a test deployment approximately 2 miles off the Villefranche coast during a warm day of May. It may be the warmest temperatures these floats will ever measure during their life! The week before, we did a last check-up of the floats, which consisted in simulating a real deployment. Being confident that the floats were ready to navigate the harsh southern waters, we put them in their transport boxes, ready to be shipped.

    As a third kind of floats being deployed during the cruise, two ProVal floats are being prepared and will be ready to leave by air in September ...

    SOCLIM 2015 Progress Meeting

    Julia Uitz

    The first SOCLIM annual progress meeting was held in Banyuls on November 25–26, 2015...

    The meeting was largely dedicated to the preparation of the next SOCLIM cruise that will take place in October 2016 on-board R/V Marion Dufresne.

    This cruise represents an important milestone in the SOCLIM project because it will permit the deployment of 6 Bio-Argo profiling floats, 2 ProVal floats and 4 moorings. In addition, the scientists plan to conduct a series of biogeochemical and bio-optical measurements along the ship’s track, which will be extremely complementary to the in-situ instrumentation.

    The meeting also aimed to provide updates on ongoing scientific studies related to biogeochemical fluxes in the vicinity of Kerguelen Islands, bio-regionalization of the Southern Ocean, and detection of meso-scale structures. The presentations and fruitful discussions have opened new paths for collaborations, especially among PhD students and postdocs from the different labs involved in SOCLIM.

    Finally the meeting was an opportunity for reporting on past year’s outreach activities developed in the context of SOCLIM - such as the crowd-funding “66° Sentinels of the Polar Ocean” project, interactions with school children involved in the "adopt a float" initiative and the annual open door event “Fête de la Science” - and for setting the direction for 2016.

    Kick-off meeting

    Carolyn Scheurle

    The Southern Ocean and Climate - SOCLIM project kick-off meeting took place in Villefranche-sur-Mer in late October (2014). The principal investigators, Stéphane Blain, Sabrina Speich and Hervé Claustre welcomed the participants. After their introductory talks, the two-day meeting was dedicated to detail the work plan, to the mapping of collaborations and to the preparation of upcoming activities. ...

    The team’s scientific discussions were deepened by exchanges via the web with national and international collaborators. During the meeting, the involvement of early career scientists, PhDs and postdocs has been favored. Also, the active participation of the representative of the BNP Paribas foundation was particularly welcome.

    Furthermore, the meeting marked a starting point to launch specific outreach activities and to prepare for the upcoming press conference in Paris.

Extreme meteorological and oceanic conditions make the Antarctic realm one of the least known and mostly under-sampled parts of the world.
