Scientist Martin Brogger aboard the MY Esperanza takes samples of phyto and zooplankton in the Argentine Sea, for further investigation on the feeding grounds of Southern Right whales.
The Greenpeace MY Esperanza ship is 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.
