The Holocene, 15, 161-176, 10.1191/0959683605hl797rp information crossReference sciencePaper eng; USA geoscientificInformation Date Range: 5932 cal yr BP to 19 cal yr BP; 6.45 6.98 60.25 60.35 -3982 1931 STUDY NOTES: The lakes Dravladalsvatn (60° 15'N 6° 27'E, 938m.elev) and Vassdalsvatn (60°21'N 6°59'E, 490m. elev.), have inflow of meltwater from northern Folgefonna, and were used to reconstruct ELA. The two glacial-fed lakes were cored using a modified piston corer taking up to 6 m long cores with diameter 110 mm. In Dravladalsvatn, an HTH gravity corer was used to retrieve sediments from the uppermost part of the lake sediments. The laboratory analyses of the cores from Dravladalsvatn included (sampling resolution on all parameters ~0.5 cm) magnetic susceptibility (MS), weight loss-on-ignition (LOI), dry bulk density (g/cm3) (DBD), water content and grain-size analysis using a Micromeretics Sedigraph 5100 (X-ray determination) (Master-Tech, 1993). Grain-size statistics were performed by Gradistat 4.0 (Blott and Pye, 2001). Analyses of the two cores from Vassdalsvatn include LOI and MS. Twenty-five bulk samples and four plant macrofossil samples were AMS dated from Dravladalsvatn and Vassdalsvatn. ABSTRACT SUPPLIED BY ORIGINATOR: The maritime plateau glacier of northern Folgefonna in western Norway has a short (subdecadal) response time to climatic shifts, and is therefore well suited for reconstructing high-resolution glacier fluctuations. The reconstruction presented here is based on physical parameters of glaciolacustrine sediments retrieved from two glacier-fed lakes and a peat bog north of the ice cap. Bulk density and modelled glacier net mass balance for the last 200 years show a remarkably similar pattern, where maximum sediment yield lags the glacier net mass balance by~10 years. The record of glacier variations has been transferred into an equilibrium-line altitude (ELA) variation curve. Glaciers respond primarily to changes in summer temperature and winter precipitation. At present there is a high correlation between the North Atlantic Oscillation (NAO) index and measured (since the early 1960s) net mass balance on maritime glaciers in western Norway (r= ~0.8). Reconstructed glacier variations from maritime western Norway are therefore considered indicative of the strength of the westerly airflow associated with NAO during the Holocene. The early phase of mid-Holocene glacier growth (5200 cal. yr BP) was characterized by gradual glacier expansion culminating in the first Subatlantic glacial event at 2300 cal. yr BP. The climate during the last 2200 years has favoured increased glacier activity at Folgefonna. High-amplitude shifts in ELA may be explained by unstable modes of the westerlies causing significant variability of winter precipitation. During the last 2000 years, Folgefonna expanded and decayed with significant decadal variability. During the latest period of the 'Mediaeval Warm Epoch', Folgefonna advanced. The Neoglacial maximum, however, was reached during the 'Little Ice Age' at AD 1750 and AD 1870. The northern Folgefonna glacial record is compared to other Holocene glacier records in Scandinavia.
