Scientists are preparing for the biggest worst policing journey & # 39; | Environment

Most people who going out of the way to avoid the amount of serious disruption, but a team of scientists are now preparing to travel for the week to the Antarctica for seven weeks so that they can be- collect marine biodiversity and its impact on biodiversity and climate change.

"The most explicit policing trip," as the partners, aims to determine the theory that rubbish from the world's largest mammal is a much more important part in to & # 39; preserving the productivity of the southern oceans of the previous faith.

"I want to show that they are eaglesystems in whales," said Lavenia Ratnarajah, a marine biogeochemist at Liverpool University. "Conservation initiatives typically focus on beauty, but that does not prove everyone. If we can show how those animals contribute to the activities In the morning, it will be easier to save them.

Whale numbers began from 95% in the early 20th century, but have grown steadily and have been recovered gradually since the introduction of global ban on the world in 1966. Now think it's between 10,000 and 35,000, and # 39; most in the Antarctic.

So far, most research focuses on breeding practices and the migrations of these great creatures, which can grow to more than 30 meters of water; length and weight of 200 tonnes – more than even the greatest dinosaurs. But the new research will consider how to add nutritional levels in Antarctic waters.

Whale behavior acts as oceanic fertilizer that encourages the growth of marine bacteria and phytoplankton – small plants that form the basis of Antarctic food and to act as the largest biological resource of of carbon behavior. Without the biological recycling of iron, the comparative Southern Hemisphere would not be able to maintain as much phytoplankton, this is the main food for krill.

The new study will attempt to quantify the effects of the compulsory effect and theoretical tests of the test; An important non-important whale is in the pole erythrosystem because the large predators – peumannan and seals – tend to sink on the ice instead of the water so that they can not afford the same nutritional benefits.

The team – along with many other scientists – on January 19, from Hobart, Tasmania on the Inquiry Line Inquiry, funded by the United States Commonwealth Science and Business Research and Antarctic Department. They first use sonar peppers to identify the location of the whales and then, when they are closed, use chips to fly over and wait for orange fragments. He can take days.

The birds, which are predominantly made with krill are circulated, first to move on the surface before going to & # 39; scattered and falling down to the floor; sea. On previous missions, researchers were required to collect samples by hand, but at present they are hidden that they can get the split into dirty work.

"You do not want to fall there. It's dry and smelling terrible," said Ratnarajah, who is expecting tweet about the tripSouth Westerly

"Sometimes I think I have the worst work in the world and sometimes I think I have the best thing."
