Within the ever-advancing area of world science, you may suppose that discovering animal poop in satellite tv for pc imagery could be of little consequence.
However for a analysis group finding out Antarctica, making such a discover led to what it described as “an thrilling discovery.”
Maybe we’d higher clarify.
After poring over photos from the European Fee’s Copernicus Sentinel-2 satellite tv for pc mission and likewise the Maxar WorldView-3 satellite tv for pc, scientists had been just lately capable of verify the existence of a brand new emperor penguin colony comprising round 500 birds.
The scientists had been capable of determine the colony from the birds’ guano stains, that are brown in shade and subsequently comparatively straightforward to identify towards the ice and rock, the British Antarctic Survey (BAS) defined in a report.
The emperor penguin is the tallest and heaviest of all dwelling penguin sorts, and final yr was declared a threatened species by the U.S. authorities as a result of results of the altering local weather.

This newest discovery signifies that scientists now have information on 66 emperor penguin colonies alongside the Antarctica shoreline, with half of those found through satellite tv for pc imagery.
“That is an thrilling discovery,” mentioned Dr. Peter Fretwell, who research wildlife from area at BAS. “The brand new satellite tv for pc photos of Antarctica’s shoreline have enabled us to seek out many new colonies. And while that is excellent news, like most of the just lately found websites, this colony is small and in a area badly affected by latest sea ice loss.”
The BAS mentioned that in response to present projections for local weather change, the penguins’ pure sea ice habitat might be onerous hit, resulting in 80% of those colonies turning into quasi-extinct by the tip of the century.
BAS additionally famous how emperor colonies within the space are tough to check as a result of they typically exist in distant and inaccessible areas. The situations at these websites typically see temperatures dropping to as little as −76 levels fahrenheit (−60 levels Celsius). It’s these elements that prompted BAS to start out utilizing satellite tv for pc imagery 15 years in the past, with scientists maintaining their eyes peeled for guano stains on the ice.
A number of years in the past, conservationists additionally began utilizing Maxar’s highly effective satellite tv for pc to collect information on one other endangered species.
