Impact of the B-15 iceberg "stranding event" on the physical and biological properties of sea ice in McMurdo Sound, Ross Sea, Antarctica
Ice cores were sampled at four stations in McMurdo Sound (Ross Sea) between 1999 and 2003. At 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...
