A condition or disorder affecting the epilimnia or surface layer of a stratified aquatic system.
From epilimnion + '-ia' suffix (condition), a rarely used technical term in limnology combining Greek root 'limne' with medical condition terminology.
This word is so specialized that it's barely used in actual science—it's like the Latin doctors gave it to limnologists just in case they needed to describe something weird happening specifically to lake surface layers!
