Humans have made first contact with a massive emperor penguin colony in east Antarctica.
The location of the colony was discovered in 2009. Researchers from the British Antarctic Survey and the US National Environment Research Council used satellite imagery to find faecal stains on the ice.
However, it wasn't until last month that the existence of the 9,000-strong colony was confirmed when three experts from Belgium's Princess Elisabeth Antarctica polar research station ventured to the remote colony on the Princess Ragnhild Coast.
Expedition leader Alain Hubert, station chief mechanic Kristof Soete and Swiss mountain guide Raphael Richard had been supporting the work of glaciologists carrying out scientific research on the Derwael Ice Rise, about 50km from the colony and 250km from their research station.
"Since we started operating along Princess Ragnhild Coast we have encountered so many emperor penguins that I was convinced that a colony must be installed somewhere in the east," Hubert said.
