Ice
The Laptev Sea is a major source of arctic sea ice. With an average outflow of 483,000 km2 per year over the period 1979–1995, it contributes more sea ice than the Barents Sea, Kara Sea, East Siberian Sea and Chukchi Sea combined. Over this period, the annual outflow fluctuated between 251,000 km2 in 1984–85 and 732,000 km2 in 1988–89. The sea exports substantial amounts of sea ice in all months but July, August and September.
Ice formation starts in September on the north and October on the south. It results in a large continuous sheet of ice, with the thickness up to 2 meters (6 ft 7 in) in the south-eastern part of the sea as well as near the coast. The coastal sheet ends at the water depth of 20–25 m which occurs at several hundred kilometers from the shore, thus this coastal ice covers some 30% of the sea area. Ice is drifting north to this coastal band, and several polynyas are formed by the warm south winds around there. They have various names, such as the Great Siberian Polynya, and can stretch over many hundreds kilometers. The ice sheet starts melting in late May-early June, creating fragmented ice agglomerates on the north-west and south-east and often revealing remains of the mammoths. The ice formation varies from year to year, with the sea either clear or completely covered with ice.

Famous quotes containing the word ice:
“Goodness and evil never share the same road, just as ice and charcoal never share the same container.”
—Chinese proverb.
“Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.”
—Henry David Thoreau (1817–1862)
“The awaited scream rises,
the shattering
of glass and the cracking
of bone
a polar tumult as when
black ice booms....”
—Denise Levertov (b. 1923)
