Monitoring of glacier termini

Since 1930, volunteers from the Iceland Glaciological Society have carried out regular monitoring of the snouts of many of the outlet glaciers of Vatnajökull. The monitoring involves measuring the terminus position relative to a reference point and are currently carried out annually at 35 termini country wide. The measurements, published in the journal Jökull, are a remarkable source of information about glacier variations in Iceland over a period spanning almost 100 years. They document terminus retreat and advance, and in some cases surges. The results are submitted to the international database on glacier variations, World Glacier Monitoring Service. The measurements, as well as maps showing the locations of the measurement sites and the annual reports on terminus variations, published in Jökull, are available at the glacier variations website of the Icelandic Glaciological Society.
