冰芯的形成过程,也是它记录气候变化情况的过程。由于北极圈地区(以下简称北极)和南极圈地区(以下简称南极)具有特殊的地形与气候,而且少被人类活动干扰,这里的冰芯保真性好、包含信息量大、科研价值极高。南极冰芯相比于北极冰芯,南极冰芯更受科研人员青睐。首先,南极的气温比北极还低。北极的大部分区域是北冰洋,而南极的大部分区域是陆地。相对于陆地,海水的比热容大。北冰洋 Ice core formation process, but also it records the process of climate change. Due to the special topography and climate in the Arctic Circle and the Antarctic Circle (hereafter referred to as “the Antarctic”), and less human interference with human activities, the ice core here has good fidelity, contains large amount of information and has extremely high scientific value. Antarctic ice core Compared to the Arctic ice core, the Antarctic ice core is more favored by researchers. First, the Antarctic temperature is lower than the Arctic. Most of the Arctic is Arctic Ocean, while much of Antarctica is land. Relative to the land, sea water, large specific heat capacity. Arctic Ocean
