Penguin islands living in the huge group of penguins that were concerned about sudden population from NASA's satellite image will be found

From the satellite image of NASA, it was found that an island inhabited by penguins that had never been known exists near the South Pole. I found out that I live in Penguin IslandAdelie penguinIt is said that the decrease in the number of individuals was a concern due to overfishing and depletion of feed stocks. With this discovery, the number of adelie penguin populations will increase by 1.5 million at a stretch.

In 2014 NASA 's Heather Rinhi and Matthew Schwarr have discovered that dark shades appear in the area of ​​Antarctica Danger Islands (Danger Islands). It seems that it is named Danger Islands because it is a dangerous area shielded by thick sea ice.


The satellite image


As a result of the analysis, what was reflected was "guanoIt turns out that Hun called deposits called. It is predicted that penguins inhabit the island because guanos containing pink pigment contained in crustaceans such as krill which Adelie penguin eats are densely concentrated in the islands. It is said that it is very difficult to find animals with white / black body color like penguins with satellite images.


In the vicinity of the island where the penguin habitat is suspected, it is a place unsuitable for human access, so far no investigation of penguins has been done. So, we formed a new large team and researchers headed to the island with the expectation that it is an unknown penguin habitat. And shortly after the team arrived at the site, it seems that we could see countless adequately large Adélie penguins.


It was difficult to measure the exact number with too many large groups. Therefore, by using a commercially available drone, the aerial photographs of the flock were separated by area, and the data mapped to 2D and 3D was analyzed on a pixel basis, and the accurate population of Adelie penguins was measured. In the cold weather, the Dron 's lithium - ion battery did not function as you would expect, and the researchers took a firm warm up in their pockets and the flight test was done.


As a result of analysis, it was found that Adelie penguin is 755,277 pairs, and more than 1.5 million adelie penguins inhabit.


The Adelie penguin population has reached 4 million pairs worldwide and has doubled in the past 40 years. However, in the vicinity of Antarctica, it was confirmed that the number of adelie penguin populations, which is considered to be caused by global warming rapidly proceeding, was confirmed. This discovery seems to be a new discovery of the huge penguin habitat next to New Zealand.
