The first leg of the Tara Pacific expedition — the Atlantic crossing — is a “can’t miss” opportunity for scientists from the Oceanographic Laboratory of Villefranche-sur-Mer (France) and the Weizmann Institute of Science (Israël). This first period of sailing is put to use collecting as much data as possible and completing the already colossal data basis on plankton established during the Tara Oceans expedition. These new samples will allow further analysis of living organisms and the incredible biodiversity of plankton.
But the presence of plastic at sea is also revealed. The fragments collected will be analyzed, including the bacteria, viruses, and other microorganisms that colonize microplastics.
Discover a series of sampling instruments:
- A peristaltic pump, designed to avoid damaging the organisms collected
- A “high speed” net to collect surface water without having to reduce the speed of the schooner
- A bottle to collect iron (nutrient essential for plankton) installed at the bow of the boat in order not to be contaminated by the aluminum hull.
These operations are complemented by various automated and continuous samplings such as collecting atmospheric particles, and survey work made by the mass spectrometer in the dry lab.
