Why scientists count the small Antarctic Carrel from space

Scientists say that the exact differences in the color of the sea will enable them to calculate small marine creatures – but of critical importance – from space.

The goal of the new research effort is Krill in the Antarctic, which is only a few inches and one of the most abundant animals on this planet.

Marine wildlife – including whales, birds, seals and sea birds – all feed on these huge creatures.

However, conservation scientists are concerned that fishing and climate change may have a negative impact on them and say we need new ways to monitor creatures.

“Krill Antarctica is the superheroes in the southern ocean,” said Rod Dawn, the chief poorest consultant at The Worlife Charity Wwf-UK.

“They are small, unknown heroes that maintain amazing marine life, but climate change and non -honest fish are at risk.”

Research from Strateclyde University, WWF and British Survey in Antarctica (BAS) develops a new way to use satellites to unify the Krill number in the ocean around Antarctica.

The key is in accurate differences in the amount of light sea absorption – depending on the Krill number in which it is swimming.

Dr. Kate McCari, from the University of Strathklaid, returned from a trip to Antarctica, where Creel caught up to measure this effect.

“We start with sea water, then add Krill and take a measurement [of how much light the water absorbs]”I made it clear. Then we add another Krill and take another measurement.”

The researchers say this analysis of how Krill changes the ocean color, allows them to take clips of Krill residents of satellite – monitoring population from space.

Krill is food for some of the largest animals on this planet – including giant whales that migrate thousands of kilometers, to Antarctica, to feed on them.

It is also the basis of a healthy environment – part of a virtuous cycle: whales eat Krill, and Krill eat microscopic plants that live in marine ice, and those plants absorb carbon that aims to the planet during their growth. When the whale tube (in vast quantities) is, this allows marine plants refrigerated on the planet.

However, with the rise in ocean temperatures with global warming, conservative scientists are concerned that this course can be disabled, and that Krill can be weak.

Mr. Downey said: “We urgently need to manage fish fisheries and protect Krill habitats within a network of marine protected areas.

“[This project could] Give us a new tool to help monitor and protect these vital species. “
