| Summary: | [ABSTRACT] Characteristics of sea-ice variation including breakup events in Lutzow-Holmbukta, Antarctica, have been investigated for the period of 1980-2003. According to satellites images, it is found that spatial and temporal scales for breakups are different among each event and that breakups have occurred at least 19 times. The geographical sites of breakups are almost the same in the bay and commencement is usually in autumn. The 1997/1998 event covered a wide area and was of long duration. Since then, autumn to early winter breakup has continued until winter 2003. It is suggested that dominant southerly wind field, small snow depth and mild winter prior to the breakup are factors which favor breakup events. Long-term monitoring of such a coastal sea-ice condition is important and useful for better understanding of the Antarctic and global change. |
