Jökull - 01.12.1982, Blaðsíða 38

photogrammetric measurements ofthe 1980photo-
graphy are yet to be made, it is clear that the eastern
extension of the spits has ceased and it appears that
there have been no significant changes in the posit-
ion of the coastline during the last 15 years.
CONCLUSIONS
The record of the changes in the position of the
frontal margin of Breidamerkurjökull andofchang-
es in its proglacial deposits, landforms, drainage
system, lakes and coastline is extremely good for the
last 90 years. It is hoped that luture changes will be
recorded and that further investigations of the pro-
glacial sediments and of the glacier itself will be
undertaken. Specifically, it is to be hoped that the
already excellent aerial photographic coverage of
this area will be continued on a regular basis.
ACKNOWLEDGEMENTS
The author is most grateful to his colleague Professor G.
Petrie for his co-operation as co-director of the Universily of
Glasgow Breidarmerkurjökull Project between 1964 and
1967 and to Dr. P.J. Howarth and Dr. R. Welch for their
participation in the project. Not only thosepersons assoáaled
with the University of Glasgow, but all the British workers
who have had the opportunity to msit Breidamerkurjökull,
extend their thanks to Dr. Sigurdur Thorarinsson, to Land-
maelingar Islands, Vegamálastjórinn and to the residents of
Kvísker and Fagurhólsmýri for their generous co-operation
over the last eighteenyears.
