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.
The lake warms up…
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. Continue reading
Lake Udyl is a huge freshwater reservoir, located among picturesque nature of the Khabarovsk territory. It is located in the Amur river basin and is one of the largest lakes in the region. The area of the surface exceeds 330 square kilometers. Longer in length by about 40 km and a maximum width of 11 kilometers, the Udyl rather like the river, bathed in the lake. The depth of the reservoir varies by season, in summer it is shallow. Maximum depth is 5 meters, the smallest – 2 m.
The scenic shoreline, framing the beautiful crystal surface of the pond. Stripped, dotted with beautiful coves, cut into the land bays, small michikami – this appears to be the Northern and South-Eastern part of the steep, massive folded schists of the coast. While the rest of it is calm forms and structures. Sand-clay surface of the coastal area is almost flat and low. Only places looming wetlands covered by luxuriant vegetation. These picturesque blotches liven up the lake, giving the surrounding landscape traditional Russian character and incredible charm.
In the waters of the shallow lakes have lost four small islets, and the confluence of rivers (Pildi, Whips and Chops) is the State reserve “Udalski”.
The rich vegetation of the coastal zone. The lake is surrounded by luxurious grass carpet, proteleuses for many miles ahead. In the lowlands rampaging unprecedented Continue reading
Lake Nakuru is located 160 km Northwest of Nairobi, a 2-hour drive from the international airport Jomo Kenyatta. At the local plane you can get there from Wilson airport, the flight takes about half an hour. Nakuru – one of the lakes along the Great African Rift. Its area is about 40 sq km and maximum depth of about 3 m.
Nakuru is a high – altitude lake, it is at the altitude of 1759 m above sea level. It is fed by two major rivers – Giro and Nderit. The lake belongs to hypersaline, due to the high content in the water of carbonates and bicarbonates, so here there are only those rare plants and living creatures which could adapt to such conditions: few algae, few species of zooplankton, small crustaceans, and only one species of fish. Surprisingly, this seemingly meager range of water flora and fauna of the lake attracts the countless numbers of birds, the most notable of these is small flamingos. These birds are different bright pink color, and on the lake they may be collected up to half a million. Such an unusual color to their feathers gives beta-carotene found in the algae spirulina, which feed on flamingos. Also it is home of Flamingo, herons, great white Pelican, yellow-beaked stork, and African eagle fishing. Continue reading
