Five studies that were just published in the journal “Science” describe some results obtained by the international consortium Tara Oceans in an expedition accomplished between 2009 and 2013 around the oceans. A group of more than 200 people traveled on the 36-meter schooner Tara to collect more than 35,000 samples in the waters of the Earth’s seas to study even at the genetic level the presence of various types of plankton.
