Frequent sea-ice breakup in Lutzow-Holmbukta, Antarctica, based on analysis of ice condition from 1980 to 2003
The history of sea-ice breakup in Lutzow-Holmbukta, Antarctica, has been investigated for the period 1980-2003. Though spatial and temporal scales for breakups are different among each event, breakup phenomena have occurred at least 19 times. The geographical sites of breakups are almost the same in...
