Within the ever-advancing area of worldwide science, you would possibly suppose that discovering animal poop in satellite tv for pc imagery can be of little consequence.
However for a analysis workforce learning Antarctica, making such a discover led to what it described as “an thrilling discovery.”
Maybe we’d higher clarify.
After poring over pictures 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 in a position to affirm the existence of a brand new emperor penguin colony comprising round 500 birds.
The scientists had been in a position to determine the colony from the birds’ guano stains, that are brown in coloration and due to this fact 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 residing penguin sorts, and final 12 months was declared a threatened species by the U.S. authorities as a result of results of the altering local weather.

This newest discovery implies that scientists now have information on 66 emperor penguin colonies alongside the Antarctica shoreline, with half of those found by way of 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 pictures of Antarctica’s shoreline have enabled us to search 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 current sea ice loss.”
The BAS mentioned that in accordance with present projections for local weather change, the penguins’ pure sea ice habitat might be arduous hit, resulting in 80% of those colonies changing into quasi-extinct by the tip of the century.
BAS additionally famous how emperor colonies within the space are tough to review as a result of they usually exist in distant and inaccessible areas. The situations at these websites usually see temperatures dropping to as little as −76 levels fahrenheit (−60 levels Celsius). It’s these components that prompted BAS to begin utilizing satellite tv for pc imagery 15 years in the past, with scientists retaining 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 assemble information on one other endangered species.
