对南极墨尔本山和北方维多利亚地坎贝尔冰川两个雪剖面的氘氢分析表明,积雪速率为0.5-2.2 m/a。根据墨尔本山冰崖中火山灰层的埋藏深度,估计最后一次大喷发发生在1862年至1922年之间。
Abstract Deuterium/hydrogen analysis of two snow profiles on Mount Melbourne and the Campbell Glacier, northern Victoria Land, Antarctica, indicate snow accumulation rates of 0.5–2.2 m/a. From the depth of burial of ash layers in ice cliffs at Mt Melbourne it is estimated that the last major eruption was between 1862 and 1922.
