Satellite Images Capture More Penguins
A recent study has claimed that there are a lot more numbers of emperor penguins around the coastline of Antarctica unlike the previous reports that indicate that the population of the same is facing a drop due to global warming.
It has been further claimed that with the help of high-resolution satellite images, scientists have managed to track down emperor penguin to 595,000. "It gives us a bit more confidence not only that there are lots of emperor penguins out there but that we can actually keep track of them as well”, said team leader Peter Fretwell of the British Antarctic Survey, who screened each of 44 colonies around the coastline of Antarctica before making the claim. Among the total scanned, seven were found for the first time.
The best part of satellite images is that at one point of time, numerous images of the same can be taken, while capturing them live at locations with temperature as low as 50 degrees Celsius (-58 degrees Fahrenheit) is found to be too costly and even this would take a hell lot of time. Though there could still be error of 10% to 12%, the final figure is almost confirmed.
Published in the online journal PLoS ONE, this is by far the first study to have figured out the exact population of any species by satellite in a single season. There are fair chances that some other species which as of now appears to be lost somewhere might be captured in the same way.
It was further said that though tracking down any species from space is no way easy, it was found that emperors were large enough to be identified against the white snow and ice on which they are found.
While the team is enthralled with the revelation, it would be interesting to see what all scientists would be able to explore with the evidence in their hands.
