At the beginning of the austral winter starting around
March, the loose pack ice that has spent the summer months circling
Antarctica begins to drift northwards. Pack ice is old sea-ice,
frozen sea water that is a year old or more, it froze and formed
elsewhere and later floated off with the winds and currents. Pack
ice is heavy stuff and when it arrives somewhere it has the effect
of steadying the ocean swell. The continuous rolling motion of the
sea is stopped completely by a relatively narrow band of pack ice
only 100m or so wide. The result is that where pack ice is present
in reasonable quantity, the sea calms down sufficiently for low
temperatures to freeze it easily - moving water cannot freeze as
easily as static water.
