The Ross Ice Shelf, straddling the protected waters of the Ross Sea off Antarctica, has produced an iceberg three times the size of Long Island. A massive raft of ice about 208 km long, 53 km wide, and 250 m thick calved cleanly off the shelf in late September or early October and is currently moving away from the coast at about 200 m/hour, heading west and, of course, north. It is the largest piece of floating ice on record, and if it can stay in one piece for a trip to slightly lower latitudes, it may drift into westerly ocean currents and be carried in a victory lap all the way around the continent.
