Scientist Martin Brogger takes samples of phyto and zooplankton in the Argentine Sea, for further investigation on the feeding grounds of Southern Right whales.
He is traveling with Greenpeace on the MY Esperanza ship, in Argentina as part of the Protect the Oceans Tour, a year-long pole-to-pole expedition that began in the Arctic and will arrive in Antarctica, to denounce the fishing industry and seek approval from the UN for a global treaty for the protection of the oceans.
