Editor's Note: The caption below, published on May 10, 2001, is incorrect. According to Masha Vorontsova, director of the International Fund for Animal Welfare in Moscow, the situation with the seal pups in the White Sea is normal. There is no disaster and there never was. For more details, refer to the article entitled "No Danger" on the New Scientist home page. The Earth Observatory regrets the earlier errant report.
Original Caption
According to the Russian Polar Research Institute for Fisheries andOceanography, between 250,000 and 300,000 Greenland seal pups face deathby starvation over the next two months due to a cruel trick by mothernature. The seals, most of them less than two months old, are trappedon ice sheets that remain locked in the White Sea, located nearArchangel in Northern Russia. Typically, during the spring thaw the icesheets break up and flow with the currents northward into the BarentsSea, the seals' spring feeding grounds. The seal pups hitch a ride onthe ice floes, living on food caught by their mothers until they arrive in the Barents Sea. Unfortunately, their mothers departed for the Barents Sea weeks ago leaving the pups with only their own individual stores of fat to sustain them.
In a normal year, the seal pups' trip from the White Sea out to theBarents takes about six weeks, and the seals have adapted to rely uponthis mechanism of mother nature. During their yearly migration, themother seals usually stay with their pups and feed them until theirpelts turn from white to grey--a sign that the pups are mature enough toswim and feed themselves. Unfortunately, this year unusually strongnortherly winds created a bottleneck of ice near the mouth of the White Sea, thus blocking the flow of ice and trapping the pups.
These true-color images of the White Sea were acquired by theModerate-resolution Imaging Spectroradiometer (MODIS), flying aboardNASA's Terra spacecraft. The top image, taken May 3, 2001, shows thelarge ice shelf still trapped in the White Sea. The bottom image wastaken by MODIS almost this same time last year (April 23, 2000). Noticethere was much less ice in the White Sea this time last year as most of it was en route to the Barents Sea.
