Disappearing Arctic Lakes
L. C. Smith,1* Y. Sheng,2 G. M. MacDonald,1 L. D. Hinzman3
Historical archived satellite images were compared with contemporary satellite data to track ongoing changes in more than 10,000 large lakes in rapidly warming Siberia. A widespread decline in lake abundance and area has occurred since 1973, despite slight precipitation increases to the region. The spatial pattern of lake disappearance suggests (i) that thaw and "breaching" of permafrost is driving the observed losses, by enabling rapid lake draining into the subsurface; and (ii) a conceptual model in which high-latitude warming of permafrost triggers an initial but transitory phase of lake and wetland expansion, followed by their widespread disappearance.

We compared satellite imagery acquired across 515,000 km2 of Siberia in the early 1970s with recent (1997 to 2004) satellite data to inventory and track ongoing changes in more than 10,000 large lakes after three decades of rising soil and air temperatures in the region (1, 3, 4). Our analysis reveals a widespread decline in lake abundance and area, despite slight precipitation increases (4). The spatial pattern of lake disappearance strongly suggests that thawing of permafrost is driving the observed losses.
Between 1973 and 1997–98, the total number of large lakes (those >40 ha) decreased from 10,882 to 9712, a decline of 1170 or 11% (SOM text). Most did not disappear altogether, but instead shrank to sizes below 40 ha. Total regional lake surface area decreased by 93,000 ha, a 6% decline. One hundred and twenty-five lakes vanished completely and are now revegetated, as indicated by sharp increases in near-infrared reflectance (Fig. 1, B and C). Subsequent monitoring of these former lakebeds (2000 to 2004) confirms that none have refilled since 1997–98. These lakes are therefore considered to be permanently drained.
