In honor of Penguin Awareness Day, researchers from British Antarctic Survey announced the discovery of a new colony emperor penguins thanks to satellites.
Scientists discovered the colony by comparing satellite images taken by the European Space Agency’s (ESA) Copernicus Sentinel-2 mission and private company Maxar’s WorldView-3 satellite.
That’s how they found them
According to the study, the main trace for the discovery of this colony, which is 66% within the continent, was guano left by seabirds.
This population is estimated to be at least 500. penguins.
Of the 66 colonies known to man in Antarctica, exactly half have been discovered using satellites.
Copernicus Sentinel-2 is one of the satellite missions being developed and used by the European Space Agency as part of the European Commission’s Copernicus environmental monitoring programme. Sentinel-2 has been collecting images of Antarctica since 2016 at the request of SCAR, the Scientific Committee on Antarctic Research. Maxar Technologies – commercial supplier satellites.
Influenced by climate change
“This is an exciting discovery,” said Dr. Peter Fretwell, one of the researchers who led the study. “[Pero] Like many of the newly discovered sites, this colony is small and located in a region that has been severely affected by the recent loss of sea ice.”
emperor penguins they are the only ones known to breed on ice, making them particularly vulnerable to climate change.
The birds need the ice around their colonies to last from April to September so that their young have enough time to grow. “If the ice melts before then, the chickens will fall into the water and drown or freeze,” Fretwell said.
A recent study indicates that penguins they may become extinct by the end of the century if global warming is not limited.
