ENDURMÆLING Á JAÐRI
GLJÚFURÁRJÖKULS
C. J. Caseldine, University of Exeter
Greint er frá mælingum á sporði Gljúfurárjökuls,
sem sýna að hann hefur skriðið fram um 30 m frá
árinu 1979. Rætt er um aldursgreiningu á jökulöld-
um með athugun á fléttum. Þvermál flétta er mæli-
kvarði á þann tíma, sem liðinn er frá því land varð
jökullaust og landnám gróðurs hófst.
