When will the big iceberg, B-15, break up?
Scientists think it will certainly break up but are not sure when. A New Zealand scientist said, “B9 took 22 months if you discount that piece of thin shelf starting life as multiyear fast ice at its eastern end. B9 was generally thicker but had a big N-S rift in it (Kainan Bay). B-15 is 100-350m thick with an unsustainable length -width ratio but it may stay side on to the swell for a while yet and these will be dampened by the forming pack.
