Disappearing arctic lakes linked to climate change

Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from 1997-2004. Researchers, including Larry Hinzman with the Water and Environmental Research Center at the University of Alaska Fairbanks, tracked changes of more than 10,000 large lakes over 200,000 square miles.

"This is the first paper that demonstrates that the changes we are seeing in Alaskan lakes in response to a warming climate is also occurring in Siberia," said Hinzman, who has also compared satellite data of tundra ponds on the Seward Peninsula near Council, Alaska and found that the surface pond area there had decreased over the last 50 years.

In this latest study, comparing data from 1973 with findings from 1997-98, the total number of large lakes decreased by around 11 percent. While many did not disappear completely they shrank significantly. The overall loss of lake surface area was a loss of approximately 6 percent. In addition, 125 lakes vanished completely and are now re-vegetated.

Laurence Smith, an associate professor of geography at the University of California Los Angeles, is the article's lead author. Smith and his co-authors were surprised by the overall loss in surface water.

"We were expecting the lake area to have grown with climate change," said Smith. "And while it did do so in the north where the permafrost remains intact, lake area did not increase in the south where permafrost is warming."

In permafrost regions, summer thaw produces meltwater, which is typically unable to infiltrate into the ground because of the ice-rich frozen soils found in permafrost. Data gathered from the latest measurements indicate that warming temperatures lead to increased numbers of surface water bod
