This article focuses on a study that investigated change of several glaciers in Spitsbergen Island, Norway since 1993 using surface photographs. Included is an illustration of the drainage basin of Tunabreen, as well a its photographs taken in 1933, 1993 and 2004. According to the photos taken in 1933 and 1993, the thickness of the glacier retreated and decreased at the terminal in 60 years. Results of the study showed that the estimated height of glacier surface in 1933 was 120 meter (m) above sea level (a.s.l.), 90 m in 1993 and 95 m in 2004. The study also found that the glacier terminal of Tunabreen retreated with a mean rate of 88 m/year until the next occurrence of a surge in 1970. |
