Grease ice is a term used in glaciology and oceanography to describe a very early stage of sea ice formation. It appears as a soupy, oily layer on the surface of the water, resembling grease or slush. This stage is characterized by a concentration of ice crystals that are not yet interlocked or frozen together to form a solid sheet. The crystals are typically small and dispersed, giving the water a duller appearance than the surrounding unfrozen ocean.
Grease ice forms when the water temperature drops below its freezing point, which is slightly lower than
The formation of grease ice is an indicator of impending significant sea ice development. It is often
