Tara Oceans 2013: the expedition prepares for departure to the Arctic - Futura Sciences

Quentin Mauguit, Futura-Sciences

Day J-2 before the start of the Tara Oceans expedition Polar Circle in 2013 , which is going to tour the Preparations are well underway on the edge of a dock Lorient, where the schooner Tara is preparing for its next scientific expedition Tara Oceans Polar Circle 2013 . “It’s a bit of a mess, but will find a place at the last moment” , according to Roman Confused, the Secretary General of Tara Expeditions Futura-Sciences contacted. The number of things in store when you take the sea for seven months is actually so. “There is food everywhere, under the bunks in the funds, etc.. “, even if fresh food will be purchased during the stops.

schooner cast off Sunday, May 19 at 15 h 00, carrying 14 crew members. She will head the Faroe Islands, to begin his journey of 25,000 km around the North Pole anticlockwise so by first taking the legendary “Northeast Passage is” off Siberia . “We know about the path we will follow, but navigation and precise choice of sampling sites depend on a mix between weather, sea conditions and satellite data (characteristics of masses water Tara Oceans Polar Circle is primarily a scientific adventure that will complete the ambition of Tara Oceans. During a previous year a little less than three years (September 2009-March 2012), 126 scientists were relayed to the schooner to collect and analyze water samples and plankton they contained, in all oceans of the world, except … in the Arctic.

The Specifically, the schooner at sea should stop two or three times a month, for a period of two days, to achieve a variety of samples. These will be performed at three different depths: surface, between 0 and 200 m (where there is more phytoplankton, because of the presence of Nutrient molecule ‘s Foodborne can be absorbed as such in ‘ s body, such as glucose or vitamins.

In addition, during the movement of the ship, physico-chemical measurements will be carried out continuously by fifteen dedicated devices such as temperature, salinity, “The Larva In animals in general, young form, the morphology and often the lifestyle is very different from the adult (tadpole / frog or toad, for example).

The study of plankton is not trivial, as the information it provides are numerous, especially in this sensitive region to global warming.

The schooner Tara , purchased in 2003 by the designer Agnès b. and Etienne Bourgois, the CEO of the eponymous clothing brand has received some additional systems for their future trip. “A hot plate was installed on the bridge to prevent the CTD rosette freezes” , since the temperature should range between -10 ° C and 5 ° C. The laboratory bridge, where they held scientific filtration, and the forward compartment were also equipped with a heating system because “some samples, as well as fruits and vegetables should not freeze” .

Finally, a camera system is currently installed on the boat. Five minutes of daily shipping and will be filmed and shown on This topic interested you? More here …
