Lena Delta in Sibera Shakes Off Winter
For most of the year, the Lena River Delta–a vast wetland fanning out from northeast Siberia into the Arctic Ocean–is either frozen over and barren or thawed out and lush.
After seven months encased in snow and ice, the delta emerges for the short Arctic summer. Green areas are likely the result of organic matter (debris from leaves, branches, and peat) dissolved in the water.
