C19a

After that the Ross Ice Shelf returned to the size it was in 1911, when it was mapped by Robert F. It was the second-largest iceberg to calve in the region in a few years (after B-15).It had a surface area larger than 5500 km²
During 2002 C-19 prevented sea ice from moving out of the southwestern Ross Sea region and this blockage resulted in an unusually high sea ice level during spring and summer, thus provoking a huge reduction in phytoplankton production which is at the base of the food chain.
In summer 2003 C-19 moved northward very rapidly, passed Cape Adana, and broke in two pieces: C-19A and C-19B.
In September 2005, after a two year stay along the coast of Victoria Land (west of French station Dumont d'Urville) C-19A started drifting northward. In March 2006 its location was in the Pacific Ocean, 200 km west of Balleny Islands.
In 2008, C-19A was renamed Melting Bob as a result of a contest sponsored by the Hay Festival and the Scott Polar Research Institute.
