Anchor Ice

Anchor ice is defined by the World Meteorological Organization as "submerged ice attached or anchored to the bottom, irrespective of the nature of its formation." It may also be called bottom-fast ice.Anchor ice is most commonly observed in fast-flowing rivers during periods of extreme cold, at the mouths of rivers flowing into very cold seawater, in the shallow sub or intertidal during or after storms when the air temperature is below the freezing point of the water, and the subtidal in the Antarctic along ice shelves or near floating glacier tongues, and in shallow lakes.

    The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
    Always yield to the Hands-On Imperative!
    All information should be free.
    Mistrust authority—promote decentralization.
    Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
    You can create art and beauty on a computer.
    Computers can change your life for the better.

    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)
