Scientists are building a sensor network to detect the trends in the water chemistry of Lake Huron, one of the five Great Lakes of North America.
- It is the first step towards developing a system that would be capable of measuring the carbon dioxide and pH levels of the Great Lakes over several years.
More In News
- It is known that the increase in atmospheric carbon dioxide has caused the world’s oceans to turn more acidic.
- Recently, it has been observed that by 2100, even the Great Lakes — Superior, Michigan, Huron, Erie, and Ontario — might approach acidity at around the same rate as the oceans.
About Great Lakes
- They are believed to have been born some 20,000 years ago when the Earth started to warm and water from melting glaciers filled the basins on its surface.
- The Great Lakes are, from west to east: Superior, Michigan, Huron, Erie and Ontario.
- They are a dominant part of the physical and cultural heritage of North America.
- The Great Lakes basin encompasses large parts of two nations, the United States and Canada.
- They drain into the Gulf of St Lawrence in the North Atlantic through the St Lawrence River.
- They contain a fifth of the world’s total freshwater and are a crucial source of irrigation and transportation.
- They also serve as the habitat for more than 3,500 species of plants and animals.
