Kon-Tiki2 : NIVA's three-stage sampler deployed

November 15th, the Kon-Tiki2 Expedition deployed an advanced three-stage sampler in the South Pacific. The goal of the operation is to detect plastic fragments of varying sizes.

The sampler, developed and sposored by NIVA, the Norwegian Water Research Institute, pumped 15,000 litres of South Pacific water through three filtes at a rate of 5 litres per second. The goal of the operation is to detect plastic fragments of varying sizes. The pump drew significant amounts of power from the solar-based power bank. The crew, however, were happy to sacrifice electrons in the name of science – electrons what would otherwise be wasted in onboard personal entertainment systems. The sampler is heavy and must be handled by 2-3 people. Conditions at sea were dynamic, with winds around 14 knots. The sail was lowered during deployment.
