It is the second time in just four years that such devastation – not previously seen in more than 50 years of observation – has been wrought on the population.
The finding has prompted urgent calls for the establishment of a marine protected area in East Antarctica, at next week’s meeting of 24 nations and the European Union at the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) in Hobart.
In the colony of about 18,000 breeding penguin pairs on Petrels Island, French scientists discovered just two surviving chicks at the start of the year. Thousands of starved chicks and unhatched eggs were found across the island in the region called Adélie Land (“Terre Adélie”).
The colony had experienced a similar event in 2013, when no chicks survived. In a paper about that event, a group of researchers, led by Yan Ropert-Coudert from France’s National Centre for Scientific Research, said it had been caused by a record amount of summer sea ice and an “unprecedented rainy episode”.
