Holocene cirque glacier activity in western Spitsbergen, Svalbard
Holocene glacial variations of a presently ice-free cirque in western Spitsbergen are inferred from sediment records from the proglacial lake Linnévatnet. Glaciation is indicated in the core records by increased intensity of laminae derived from the cirque inflow and by increase in sediment accumulation rate. Radiocarbon ages on terrestrial plant macrofossils limit the onset of glaciation in the cirque to within the last six centuries. No evidenc…
AMS-radiocarbon dating of organic-poor lake sediment, an example from Linnévatnet, Spitsbergen, Svalbard
AMS-radiocarbon dating of specific organic fractions is used to evaluate sources of errors in dating of organic-poor lake sediment from Linnévatnet, a proglacial arctic lake. Dates on un differentiated (bulk) organic matter are much too old because of contamination from detrital coal. Attempts to remove coal from other organic matter were only partially successful, a consequence of the wide grain-size distribution of the coal. Even if coal contam…
