Tara’s Summer

From June through August, Tara will be sailing around French Polynesia, making a mission to study coral reefs in the Gambier Islands and a
mission employing a glider (remote-controlled submarine) in the Marquesas Islands.

Study on coral reefs in the Gambier Islands

A mission to study corals will take place in the Gambier Islands from June 25 to July 10. 30 dives (2 per day) are programmed. Besides studying the biodiversity of the Gambier corals, this mission aims to expand and complete our knowledge about Indo-Pacific coral reefs in the context of climate change. This study follows those carried out by Tara at Djibouti, Saint Brandon (Maurice) and Mayotte in 2010.

This mission will be directed by Francesca Benzoni, who coordinates Tara’s coral reef studies and is a scientist at the Research Institute for Development (IRD) in Nouméa.

It’s the first time that coral studies will be correlated with plankton analysis during the Tara Ocean Expedition. The scientific consortium hopes to establish the links between coral reef life and planktonic organisms.

Why is it interesting to do this study in the Gambier Islands?
by Michel Pichon,
Tropical Marine Consultant

“Contrary to the Marquesas Archipelago, the Gambier Islands have been the object of only a very limited number of expeditions and scientific studies, partly due to their relative isolation. With respect to Scleractinia (stony corals) and coral reefs, the only available publication (by Chevalier), dates back to 1974, when missions were carried out by the MNHN (National Museum of Natural History) under contract with DIRCEN (Direction Center for Nuclear Experiments). In his publication, Chevalier mentioned (after synonyms were updated) the presence of 54 Scleractinia and Zooxanthella species. This number is abnormally low, in comparison to the number of species found in other zones and localities of the region.

Gambier’s coral fauna is strikingly less abundant than that of Mururoa, and approximately the same quantity as found at Pitcairn, even though Gambier is situated more to the east and above all more to the south (250 04’ S). This situation is not consistent with biogeographic considerations, which suggest that the Gambier coral fauna in particular should be significantly more diversified than that of Pitcairn. Especially since the morphological diversity of Gambier coral structures (fringing reefs, emerging barrier reefs, submerged barriers, lagoon formations) is in itself a factor in species diversification (due to the many different types of milieu). Probably the apparent lack of coral diversity is an anomaly resulting from very insufficient sampling.  Although the authorities were informed of this situation, no initiative to rectify it has been made until now. To summarize: our knowledge about Gambier coral fauna is very incomplete, and more research needs to be done concerning  the biodiversity and the biogeography of the Scleractinia.?


Stopover at Mangareva (Gambier Islands), June 22-25 and July 10-13.


Mission employing a glider in the Marquesas Islands


A mission employing a glider (remote-controlled submarine) and drift buoys is programmed for the open sea surrounding the Marquesas Islands, lasting 12 days beginning on July 24. The goal is to characterize the prevailing planktonic ecosystem under the influence of island winds. The zone is located in a phytoplankton “bloom?. The glider and drift buoys record the physico-chemical data of the water, while the team aboard Tara receives the information in real-time, resulting in a 3-D cartographic rendering, and subsequently biological sampling will take place at the most pertinent locations. Another operational  buoy (Provbio) will take vertical sampling in the water column to help characterize the sampled water.

This mission is co-directed by Fabrice Not (scientific coordinator of Tara Oceans) from the Biology Station in Roscoff (CNRS-UPMC), Daniele Iudicone
(also scientific coordinator of Tara Oceans) from the Stazione Zoologica in Naples, and Fabrizio d’Ortenzio from the Oceanography Laboratory in Villefranche sur Mer (CNRS-UPMC). The mission is a collaboration between the LOCEAN Laboratory in Paris, the Ecole Normale Supérieure (ENS) in Paris, the French Research Institute for Exploration of the Sea (IFREMER) and the Insular Research Center and Environment Observatory (CRIOBE) in Moorea, French Polynesia.

Stopover at Taiohae (Marquesas Islands), July 21-24.

Tara Mediterranean expedition
From April to November 2014


After more than 4 years sailing around the world and the Arctic, Tara is preparing a mission with two objectives : to accomplish a scientific study concerning plastic pollution and to promote awareness of environmental challeges in the Mediterranean Sea, cradle of our civilization.

A traveling exhibition and films will be shared with the public. We will also welcome classes aboard at each stopover. Artists will be in residence on Tara for the duration of the expedition.

Ocean Sciences meeting

02/28/2014

The biennial Ocean Sciences Meeting that took place recently in Honolulu, Hawaii (February 22 - 28, 2014) is the most important international symposium in oceanography. It brings together all the scientific disciplines (physics, chemistry, geology, biology) as well as the social sciences. Nearly 5,000 scientists attended.

Lars Stemmann, Chris Bowler, Hiroyuki Ogata, Colomban de Vargas and Emmanuel Boss – scientists involved Tara Oceans – organized a session on the integrated study of ocean ecosystems during which more than 20 researchers shared their work with a full audience. Exchanges took place concerning oceanic biodiversity (methods and estimations) and its sensitivity to changes at different scales of time and space (including transport by ocean currents). Scientists discussed their results and methods. Contacts were made to share and promote internationally the outstanding data resulting from the Tara Oceans expedition.

The Tara Oceans expedition discovers a new coral reef species from the Gambier Islands, French Polynesia

07/29/2013

A new shallow water coral species, Echinophyllia tarae sp. n., is described from the Gambier Islands, French Polynesia. The remote and poorly known Gambier islands were explored by the Tara Oceans international research expedition in 2011. Scleractinia, also called stony corals, are ancient and structurally simple marine animals which have the ability to form hard skeletons and are involved in the build up of coral reefs. This new coral is common in the lagoon reefs of the Gambier, and was observed in muddy environments where several colonies showed partial mortality and re-growth. The paper devoted to the new species was published in the open access journal ZooKeys.

Ban Ki-Moon, Secretary General of the United Nations speaks to Tara at Rio +20

06/21/2012

Part of the speach :

"Earlier this year, I had the chance to board the Tara Expeditions when it docked in New York.
The crew was really inspiring. They shared so much information with me about oceans and climate change. I am really grateful that they are raising awareness around the world … and I am very proud that the United Nations is supporting them.
As I stood on the Tara that day in February, I stood on the deck and looked out at downtown Manhattan. We were surrounded by skyscrapers but we had a window on the deep blue sea. It was a reminder that our worlds are connected.
I promised the crew that I would continue working with dedication for the planet’s oceans.
Now, Rio has to put more wind in our sails, so we can navigate the waves to a better future.
Let us advance for our oceans and our world."
