Abraham Lake is an artificial lake created in 1972, on North Saskatchewan River in Western Alberta, Canada. The icy man-made lake was made during the construction of Bighorn Dam and owes its name to Silas Abraham, an inhabitant of the Saskatchewan River valley in the nineteenth century.The organic matter generated after the death of organisms, including plants, leaves and animals, falls into the water body and sinks to the bottom. The micro-organisms at the lake-bed munch on this dead organic matter and methane is released in the process. The white rock substance known as methane hydrate from deep beneath the Earth’s crust and from the ancient oceans remains also contributes to the methane output in the lake.During the winter season, this methane gas fails to escape into the atmosphere when it comes in contact with the iced water of the lake and turns to white fl oating blobs. The methane bubbles stack up into columns below the surface, as the weather gets colder and colder. As winters set off and the lake defrosts, the bubbles break free and rise to the top, releasing the methane into the air.

However, this phenomenon is not restricted to just Abraham Lake; methane forms in millions of water bodies around the Arctic region as well. But due to decreasing permafrost more and more of this methane is being released into the atmosphere. This is a cause of concern for climate scientists who note that methane is a potent greenhouse gas. It possesses 20 times the effect on climate change than the same amount of carbon dioxide over a 100-year span.

The experts have found ways to extract this natural frozen gas from deposits of icy methane hydrate buried in the ocean floor and thus it can prove to be a newfound energy reserve for the countries with scant energy resources.
