Two new colonies of penguins were located near East Antarctica’s Mertz Glacier,says a report.
The report in the Science Daily said:”While about 2500 chicks of emperor penguins are raised this year at the colony close to the French Dumont d’Urville Station, two new colonies totalling 6000 chicks have just been observed about 250 km away, near Mertz Glacier by the scientists Dr André Ancel and Dr Yvon Ancel, from the Institut Pluridisciplinaire Hubert Curien in Strasbourg.
“Since a pair of emperor penguins may only successfully raise one chick a year, the population of breeding emperor penguins in this area of the Antarctic can therefore be estimated to more than about 8500 pairs, about three fold that previously thought”,said the report.
“The two new colonies have been revealed on 1st and 2nd November, during the late winter season trip of the MSS Astrolabe1 towards Dumont d’Urville. They are located on the winter sea ice. This ice surrounds the remains of the Mertz Glacier, from which a large ice wall, 80 km long, 40 km wide and 300-400 m thick has separated.
These may be two sub-populations originating from the initial Mertz colony which, following the Mertz Glacier break, are attempting to settle again on favorable surroundings. One accounts for about 2000 chicks and the second for about 4000 chicks,”report adds.
