Why scientists are counting tiny Antarctic krill from Space
Scientific correspondent, Broadcasting Corporation News
Scientists say that the subtle differences of seawater will enable them to calculate the tiny space (but the vital-Antarctic marine life).
The goal of the new research work is Antarctic Phosphate. It is a few inches long and is one of the most important and most important animals on the planet.
Ocean Wild Plants-including whales, penguins, seals and seabirds-all eat these small creatures.
However, protecting scientists worry that fishing and climate change may have a negative impact on them and say that we need new methods to monitor these creatures.
Rod Downie, the main polar consultant of WWF-UK, a wild animal and plant charity, said: “Antarctic shrimp is a superhero of the South Ocean.”
“They are the small and unknown heroes that maintain an incredible marine life, but climate change and unsustainable fishing make them dangerous.”
Researchers at the University of WWF Strathclyde and the British Antarctic Survey (BAS) are developing a new method of using satellites to clarify how much shrimp in the ocean near Antarctica is.
The key is that there are subtle differences in absorbing how many light seawater-depends on how many phosphorus shrimps are swimming in it.
Dr. Cait McCarry, the University of Stras Claid University, just returned from Antarctica, where she captured Krill to measure this effect.
She explained: “We start from sea water, then add phosphate and perform measurement (how much light absorbs).” “Then, we add another shrimp and perform another measurement.”
Researchers said that the accurate analysis of how the density of shrimp phosphate changes the color of the ocean enables them to pick up the snapshot of the phosphate population from the satellite-monitor the species from space.
Prawn is the food of some of the largest animals on the planet-including giant whales migrating thousands of kilometers to Antarctica, with them as food.
They are also the foundation of a healthy ocean-a benign cycle: whale eats phosphorus, phosphate eats micro-plants living in the sea ice, and these plants absorb the planet carbon with the growth. When whale stool (large amount), fertilize the Earth Cold Water Ship Factory.
However, with the rise of the ocean temperature with global warming, protecting scientists worry that this cycle may be destroyed, and shrimp may be fragile.
“We urgently need to better manage the fisheries and protect the krill habitat in the ocean protection area network.
“(This project can) provide us with a new tool to help monitor and protect this important species.”
