无论是对于当地冰川还是内陆冰川，关于冰川行为的证据都是分散的，但格陵兰西南三分之一的冰川清单工作为未来对选定冰川的研究提供了基础。在数以千计的当地冰川中，几乎所有的冰川类型都被发现，包括以前只在东格陵兰岛发现的汹涌和脉动的冰川。了解冰川行为的一个基本要求是关于物质平衡的信息。对于当地的冰川，大多数这类早期调查都发生在格陵兰岛东部和北部。然而，为了可能开发水电，近年来在西格陵兰岛也对八个冰川进行了这样的调查。尽管类型和地理位置不同，但它们的质量平衡结果都表明活动指数较低。常规技术可用于确定和解释质量平衡。对于内陆冰，已经在西格陵兰岛的三个部分进行了物质平衡研究；最长的一系列研究持续了5年。然而，由于缺乏对冰下和表面地形的准确了解、邻近部门的不同反应以及冰盖表面的小坡度，对直接使用和解释常规物质平衡测量造成了严重限制。
Both for local glaciers and for sectors of the Inland Ice, evidence on glacier behaviour is scattered, but work on a glacier inventory of the south-western third of Greenland has furnished a base for future studies on selected glaciers. Nearly all glacier types have been identified among the thousands of local glaciers, including surging and pulsing glaciers which have earlier been identified only in East Greenland. A basic requirement for understanding glacier behaviour is information on the mass balance. For local glaciers, most early investigations of this kind took place in East and North Greenland. However, in connection with the possible development of hydro-electric power such investigations have also been made in West Greenland in recent years on eight glaciers. Although of different types and geographical situations, their mass balance results all indicate low activity indices. Conventional techniques can be used for determining and interpreting mass balances. For the Inland Ice, mass balance studies have been made in three sectors of West Greenland; the longest series covers 5 years. However, lack of exact knowledge of the sub-glacial and surface topography, differing responses in neighbouring sectors, and the small slope of the ice sheet surface impose severe constraints on direct use and interpretation of conventional mass balance measurements.
