Abstract
Observations on the status of the Greenland ice cover are registered at the Geological Survey of Greenland (GGU) on a routine basis. During the past two decades studies have been particularly related to technical activities such as hydro-electric power, but more recently there has been increasing interest in the significance of glacier variations as indicators of climatic change. However, whereas local glacier variations are usually related to climatic changes on the time scale of a few decades or centuries, documented changes in the status of the margins of the Inland Ice in the literature are mainly related to long term climatic fluctuations on the time scale of thousands of years or more.

Summary
Observations on the status of the Greenland ice cover are registered at the Geological Survey of Greenland (GGU) on a routine basis. A fuller discussion of the significance of fluctuations in the positions of the Inland Ice margin, on their interpretation, and on exceptions to the general trends, can be found in Weidick (1991). Recession (thinning) was marked in the areas of Qagssimiut, Frederikshåb Isblink, the head of Godthåbsfjord (Kangiata nunåta sermia) and around Jakobshavn Isbræ. This widespread recessive status of the Inland Ice margin is believed to have been part of the general recession since the major historicai (neoglacial) maximum in the middle or last half of the 19th century. The possibie influence of a warmer c1imate due to the 'greenhouse effect' which might reverse the readvance trend or reinforce it, is a topic of continuing study within GGU and elsewhere
