Also, sometimes, the width of coastal polynya activity is equal to the width of the

A method of determining areas of ice fog was created and these areas were subsequently identified on CASSTA images. The northerly location of the NOW permitted the collection of an AVHRR image every 101 minutes for seven consecutive orbits.
A sensible heat polynya is formed when a continued source of heat from the
ocean prevents ice formation. In the deep basins of the Arctic and Antarctic the
wind-driven ice dynamics usually do not permit a persistent polynya to occur.

A well-known example of a latent-heat polynya is the coastal wind-driven polynya
