C dates marked with 1) in this paper have been corrected with respect to their respective 13C/12 C ratios, but they were not corrected for sea-water influence
(365 =t 20 14C years for the waters around Iceland) when originally published. Samples showing dates marked with 2), have not had their 13C/12C ratios
determincd. Consequently the apparent age of living marine organisms cannot be subtracted from the obtained l4C values. — AldursákvarSanir sem eru

early students of deglaciation in Iceland, the reces-
sion of the inland ice sheet occurred in the form of a
frontally retreating glacier, a conclusion which still is
considered valid, at least for the deglaciation of the
area below the 100 m level.
Both Thoroddsen (1891,1905-06) and Bárðarson
(1921,1923) were of the opinion, that two stages could
be recognized in the evolution of sea-level changes.
First, recently deglaciated areas in West and North-
west Iceland were successively flooded by a rising
