The Ecosystem of the largest freshwater lakes in the world changes dramatically

Over the largest of the Great lakes — Upper began to blow strong winds. So Yes, that started to change the lake ecosystem. The cause of the phenomenon and the consequences to find out, scientists from Wisconsin.

In canadian-American shore of lake superior, the largest area of freshwater lake in the world, over the last 20 years have seen major changes. Professor of Ankur Desai (Desai Ankur) from the University of Wisconsin and his colleagues came to an unexpected conclusion: the increase in the temperature of atmospheric air in the summer has led to the fact that the speed of the winds blowing over the lake has increased. According to scientists, for the same reason, the increased speed and currents. Naturally, such changes could not but affect the inhabitants of the water.

While in sight of limnologen (Ostrovidov) managed to get only the phytoplankton. The scientists conducted their research since 1985. Based on data collected using three hydrological buoys and satellite imagery, Professor Desai and his colleagues have figured out what is going on with the Top.

Space zone

It is possible that all these puzzles have a terrestrial origin. Most likely, we are talking about the dropping of spent rocket stages. And since satellites (spy satellites, scientific stations and space ships) from year to year are displayed along well-defined trails, on the Earth’s surface formed a “zone” where almost piled in heaps of twisted aluminum tanks of launch Continue reading
