WISCONSIN, on November 16. 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 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, reports Infox .
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.
According to scientists, the temperature in the surface layers of the lake during the summer period increased at a rate of 1.2°C in one decade. And the water heats up 15% faster than the air over the lake. “The fact that the temperature regime of a lake depends largely on the amount Continue reading
The great lakes of North America – Superior, Michigan, Huron, Erie and Ontario – with their connecting channels form the largest freshwater system on Earth. Their total area exceeds 245 OOO square km, and the volume is 22 cubic km 813 – fifth of all freshwater on the planet. If you spread it out evenly across the US, she will cover her in a layer of 3 m. the Great lakes are so vast that it has identified a special climate with cool summers and abundant winter snowfall. When cold Arctic air invades into the saturated moisture atmosphere, snow literally falls asleep in the coastal town. The observer caught on the surface of the moon, able to see these lakes to the naked eye and even to identify the largest of them – the Upper, the most extensive fresh water lake on Earth. The coastline of 4500 km, the width from East to West is 560 km and from North to South 260 km, Water of this lake is fed which flows into the Atlantic ocean the St. Lawrence river.
THE LAKE, BORN OF THE EXPLOSION
Crater lake, the deepest lake in North America,was the result of a powerful eruption 7700 years ago. The explosion of the volcano Mazama in the Cascade mountains in the territory of Oregon left a crater (the Caldera) with a depth of about 1200 m, which gradually filled with water. Continue reading
When it comes to lake Baikal, the scientists unwittingly transferred into language of the highest degrees: the deepest lake in the world (1642 m), the world’s largest supply of free fresh water (23 600 cubic kilometers), 5 times exceeds the volume of the five Great American lakes combined. Moreover, the purity and the content of dissolved salts, this water is approaching distilled. Visibility in the Baikal can reach depths of 40-45 meters – as in clear tropical seas. The area, however, the lake occupies only 6th place in the world, but it can be compared with the territory of Belgium or the Netherlands. And when you consider the unique flora and fauna, rich history and picturesque landscapes, it becomes clear that the area needs to attract tourists, including divers and fishermen.
It was developed in the fishing and shipbuilding, but in the 1990s, companies were closed. But for one and a half decades, tourism has undergone all the stages of development and reached the level of modern industry. On the way to the lake you can find many fishing shops – if you forgot to take the bait or fishing line fluorocarbon, without which there will be not enough. Here you can find and pick the perfect one for yourself. Continue reading
