Barents Sea sight
I believe the answer is:
floe
'barents sea sight' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for floe that I've seen before include "Piece of ice at sea" , "Separated piece of ice on water" , "Broken piece of pack-ice" , "Frozen field" , "Part separated from a mass of ice" .)
