Scientists say they formed in depressions resulting from thawing permafrost and their water – visible in satellite pictures – is bright blue in colour.
Moscow expert Professor Vasily Bogoyavlensky says the thermokarst lakes have craters or funnels on their floor which emit previously frozen methane gas.
The "pockmarks" are similar to those seen on the bottom of the world's great oceans, he said.
The seepage is greater than in other areas of the Arctic, it is claimed.
These lakes have a number of features, which can help identify them from a distance

Images from satellites show some of the lakes on the Yamal and Gydan peninsulas in Arctic Siberia.
Professor Vasily Bogoyavlensky, the deputy director of the Moscow-based Oil and Gas Research Institute, part of the Russian Academy of Sciences, said: "These lakes have a number of features, which can help identify them from a distance."
These include a distinctive blue hue caused by algae which are attracted to the sulphur in the seeping greenhouse gas.

The craters on the floor of the lakes and traces of gas in the winter ice cover are also common features, as is active erosion on the shores and permafrost swelling at the water's edge.
The Yamal peninsula is Russia's main source of natural gas, and it is exploited heavily to boost the Kremlin's economy.
The professor warned that "many of the sites with gas emissions are located close to the territory of oil and gas deposits".

He claimed they could be a threat to extraction facilities, according to The Siberian Times.
It was revealed earlier this week that several thousand pingos, some of which are filled with gas, could explode forming giant craters in this region.
Pingos are dome-shaped mounds over a core of ice.

At least ten are known to have exploded in Siberia in recent years forming large craters.
Alexey Titovsky, the director of the Department of Science and Innovation in Yamal-Nenets autonomous region, said: "All the pingos revealed in Yamal are now monitored and in the coming summer the scientists will study them more closely."
Another linked phenomenon seen on Bely Island, off the Yamal peninsula, is bouncing turf, as shown on the video.
Below this trembling tundra is a cocktail including methane gas, another sign of thawing permafrost in the Arctic.
