Definition: A very thin, soupy layer of frazil crystals clumped together, which makes the ocean surface resemble an oil slick.  NSIDCCryosphere 

A later stage of freezing than frazil ice when the crystals have coagulated to form a soupy layer on the surface. Grease ice reflects little light, giving the surface a matt appearance. Grease ice behaves in a viscous fluid-like manner, and does not form distinct ice floes.  ASPECT2012 

A later stage of freezing than frazil ice when the crystals have coagulated to form a soupy layer on the surface. Grease ice reflects little light, giving the sea a matt appearance.  Bushuyev

Sea ice terminology which describes a later stage of freezing than frazil ice where the crystals have coagulated to form a soupy layer on the surface. Grease ice reflects little light, giving the water a matte appearance.  ECCCanada 

A thin skin of frazil crystals coagulated on the sea surface having a dark, greasy appearance. It precedes the development of shuga. (Also called ice fat, lard ice.)  AMSglossary 

A later stage of freezing than frazil ice, when the spicules and plates of ice have coagulated to form a thick soupy layer on the surface of the water. Grease ice reflects little light, giving the sea a matt appearance.  SPRI
