HOLOCENE GLACIAL HISTORY OF THE DRANGAJöKULL ICE CAP, NW ICELAND, BASED ON LAKE SEDIMENT RECORDS
We cored lakes around the ice cap in order to reconstruct the Holocene glacial history of Drangajökull from the lacustrine sedimentary records. Some of the lakes are threshold lakes, i.e. they only receive glacial meltwater when the ice cap is much more extensive than at present. Other lakes receive glacial meltwater at present. The lake sediment cores were split open, described, photographed, sampled, XRF scanned, magnetic susceptibility measured. The chronology is based on tephra stratigraphy and 14C dating of macrofossils recovered from gyttja in the cores. Here, we present preliminary results from analyses of the lake sediment cores and discuss their implications for the Holocene glacial history of Drangajökull.
