Scientists Count Penguins From Space
Scientists have discovered there are twice as many emperor penguins in Antarctica as previously thought after counting them from space.
The team, including members of the British Antarctic Survey, used very high resolution satellite images to estimate the number of penguins at each colony in the first full census of a species from space.
They were able to identify the penguins in the pictures as their black and white plumage clearly stood out against the ice and snow.
The scientists were able to analyse 44 emperor penguin colonies, with seven previously unknown.
They counted 595,000 birds, almost double the previous estimates of 270,000 to 350,000 birds.
Emperor penguins breed in areas that are very difficult to study because they are remote and often in accessible with temperatures as low as -50C.
The new results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird.
"We are delighted to be able to locate and identify such a large number of emperor penguins," said geographer Peter Fretwell, of the British Antarctic Survey (BAS), based in Cambridge.
"This is the first comprehensive census of a species taken from space."
Previous knowledge on the number of emperor penguins was poor, due to their habit of breeding on sea-ice during the Antarctic winter.
These areas are infrequently visited during the Antarctic summer when researchers can access them although the penguins are then away feeding at sea.
Two years ago scientists were able to use satellite images to see penguin poo and work out the number of emperor penguin colonies.
Now technology has moved on and the pictures can be viewed at a higher resolution so they have been able to count the actual penguins.
