Yang Liu (l) and Vikrant Shah, from North Eastern University launch a drone from a RHIB off Anvers Island, Antarctica. They use machine learning to do automated count of penguin nests to find out more about the population.
To understand how penguin populations are faring, a census has been organised by researchers from Stony Brook University, Northeastern University and Greenpeace to study the impact of climate change on fragile chinstrap penguin colonies in Antarctica.
Greenpeace is in the Antarctic to investigate the impacts of the climate crisis as part of the Protect the Oceans Expedition, a year long pole to pole ship tour, campaigning for the establishment of ocean sanctuaries to safeguard this frozen region and its penguins, seals and whales, and to help address the climate emergency.
