Аннотация

Livingston Island, one of the South Shetland Islands, Antarctica, has recorded at least three glacial events. During the oldest event, all areas of the island below 200 m were covered by an expanded island ice cap. At that time Livingston Island ice probably joined that of adjacent islands. A second, less extensive event, is recorded by deposits of both the inland ice cap and cirque glaciers. Between these two glacial events, a higher stand of sea level produced beaches and terraces at 10.6 m to 12 m above the present sea level. Following the second glacial event, a higher sea level produced beaches 6.1 m above the present sea level. A third, minor and probably relatively recent glacial event is recorded by push moraines in some cirques from which the ice has now receded.
