Temperature dropping, sea-ice begins to form
 |
This
is sea-ice in the very early stages of formation. Sea-ice that forms in
situ and is attached to the coast is called "fast-ice", it is stuck fast. In this picture the
surface of the sea is beginning to freeze as the temperature is dropping
to -20C and below. Pack ice has come near to the shore and so all movement
of the sea has been killed completely allowing low temperatures to freeze
the sea water. At this stage the ice is around an inch (2.5cm) thick but
it has a spongy texture, you could poke a finger or certainly a fist
through it relatively easily. The patterned effect comes from the rise and
fall of the tides. As the tide rises, so the surface of the sea enlarges
slightly and so the ice cracks apart, as the tide falls, so the surface of
the sea decreases slightly and so the slabs of ice overlap at the edges.
