After a voyage of 70,000 kilometres around the globe, the schooner Tara arrived in Brittany on Saturday. The scientists who took part in the two-year mission gathered thousands of samples of marine micro-organisms in a bid to better understand ocean plankton and the impact of pollution.
The survey was carried out from the 33-year-old Tara research schooner, which returned to her home port of Lorient on France's western coast at the weekend.
