jade berg
n.— «On the bridge this morning Tim the second mate spotted a “jade” berg. These are quite rare and distinctive for their opaque jade colour. This one was smallish and rounded like river stone. While no one is really sure, there is a theory that jade icebergs are formed on the bottom of the ice shelf where fresh water with algae in it has gathered and this causes them to go that colour.» —“Listening to Antartica” by Margot Foster ABC Rural (Australia) Mar. 3, 2005.
