Two Recent Massive Breeding Failures in an Adélie Penguin Colony Call for the Creation of a Marine Protected Area in D'Urville Sea/Mertz

International audience In the d’Urville Sea in East Antarctica, a population of roughly 20,000 pairs of Adéliepenguins of Iles des Pétrels (Terre Adélie) has experienced two massive breeding failures,with no chick surviving the 2013–14 and 2016–17 breeding seasons. In both seasonsthe extent of sea i...

Description
Summary:International audience In the d’Urville Sea in East Antarctica, a population of roughly 20,000 pairs of Adéliepenguins of Iles des Pétrels (Terre Adélie) has experienced two massive breeding failures,with no chick surviving the 2013–14 and 2016–17 breeding seasons. In both seasonsthe extent of sea ice in front of the colony persisted throughout the breeding cycle ofthe birds. The timing of sea-ice recession differed greatly between seasons and theabsence of polynya in a crucial phase of the cycle were paramount in driving thesefailures. The change in the icescape in front of Ile des Pétrels following the calving ofthe Mertz glacier in 2010, together with increase in precipitations and changes in sea-icefirmness explain this situation and are discussed in the present manuscript. To preventadditional future impacts on this colony, like competition with fisheries for instance, westrongly support a scientific research zone in the d’Urville Sea—Mertz area, one of thethree zones of proposed Marine Protected Area in East Antarctica to the Commission forthe Conservation of Antarctic Marine Living Resources.
