Impact of the B-15 iceberg “stranding event ” on the physical and biological properties of sea ice in McMurdo Sound, Ross Sea
the beginning of year 2000, a very large iceberg (B-15) detached itself from the Ross Ice Shelf and stranded at the entrance of the Sound, preventing the usual oceanic circulation purging of the annual sea ice cover from this area. Ice textural studies showed that a second year sea ice cover was bui...
