The Amery Ice Shelf is the largest ice shelf in East Antarctica.A new DEM was generated for this ice shelf,using kriging to interpolate the data from ICESat altimetry and the AIS-DEM.The ice thickness distribution map is conver ted from the new DEM,assuming hydrostatic equilibrium.The Amery Ice Shelf mari ne ice,up to 230 m thick,is concentrated in the northwest of the ice shelf.Th e volume of the marine ice is 2.38×10~3 km~3 and accounts for about 5.6% of t he shelf volume. 相似文献

Amery冰架DEM及其海洋冰分布研究 总被引:1,自引:0,他引:1
Amery冰架是东南极最大的冰架。利用克里格插值法对Amery冰架地区的ICESat激光高度计数据进行空间插值,建立该地区的DEM。依据流体静力学平衡原理构建Amery冰架的冰厚度图,结合冰雷达测厚数据,获得了海洋冰的空间分布。结果显示Amery冰架下的海洋冰主要位于西北部,体积为2.38×1012m3,约占冰架总体积的5.6%,冰架最大厚度为230 m。 相似文献

1 Introduction The Amery Ice Shelf, the largest ice shelf in East Antarctica, has a total surface area of about6.1×104km2. The ice shelf drains the grounded ice fromthe interior of the Lam- bert Glacier drainage basin thatcovers an area of larger than1.3… 相似文献
