Our tents were pitched on a sandy moraine shore opposite the massive Blomstrand Glacier - a monster of moving ice that lets out groans and cracks as it calves icebergs into the sea.
我们的帐篷搭在沙石的海岸上，对面是巨大的布鲁姆·斯特·莱德冰川，这是一块庞大的浮冰，当它的冰山融入海水中时，发出吱吱嘎嘎的声音。
The ground is covered with moraine. Ice under it is gray and dirty.
地表覆盖着冰碛石。底部的冰呈灰色并且肮脏。
Glacier has a narrow spectrum on TM5, 7 bands, but moraine and snow and ice are different in evidence, therefore, TM5, 7 are advantageous bands for extracting glacier information.
冰川在TM 5、7波段光谱值范围窄，且冰碛与冰雪有明显的光谱差异，是冰川信息提取的有利波段。
