“…The crystalline terrain of Liverpool Land is characterized by an alpine topography with local glaciers and small ice caps. Earlier studies have suggested that the interior of Jameson Land was ice-free during the last glacial cycle and that the last advance of the Greenland Ice Sheet overriding the peninsula occurred during Marine Isotope Stage (MIS) 6 (Funder et al 1994(Funder et al , 1998Mö ller et al 1994). This was based on the weathered appearance of the central plateau areas of the peninsula and the lack of glacial deposits of Weichselian age.…”

“…During the Late Weichselian, when a large amount of the glaciofluvial and glaciolacustrine sediments in the valleys of eastern Jameson Land was deposited, the climate was drier and colder than present (Johnsen et al, 1992;Funder et al, 1998). It seems to have been more dust in the air (Johnsen et al, 1992) but the effect of this on e.g.…”

Ripple-laminated sandy deposits at shallow water depths in four rivers on Jameson Land, East Greenland were sampled for optically stimulated luminescence (OSL) dating. Silt-sized grains have significantly higher equivalent doses (~1.1 Gy) than sand grains (~0.1 Gy). This suggests that coarse grain-size fractions are better bleached and more suitable than fine grains for OSL dating of glaciofluvial/fluvial sediments. A sample from a sidebar deposited during the spring flood yielded 1.0 Gy (~500 years) while a subaerial deposit was completely zeroed. The spring flood deposit is considered to be most similar to deglacial conditions and incomplete bleaching of this amount (1 Gy) is generally not a significant source of error for sediments of Pleistocene age. Most samples have rather poor luminescence characteristics and are affected by thermal transfer if preheat temperatures at or above 260°C are used.

“…This huge fjord and surroundings have been subject to detailed studies over the past decade (Funder et al, 1998). Although these concentrated on the last interglacial-glacial cycle, the chronology of the last deglaciation also has been investigated.…”

“…The laminated sediments are underlain by homogeneous sediments, which were referred to the Allerød. Thus it was suggested that the outer part of the fjord was deglaciated during the Allerød (Marienfeld, 1991;Dowdeswell et al, 1994;Funder et al, 1998). It should, however, be stressed that there is no solid dating evidence for such an early deglaciation.…”

A new deglaciation chronology for the ice-free parts of Greenland, the continental shelf and eastern Ellesmere Island (Canada) is proposed. The chronology is based on a new compilation of all published radiocarbon dates from Greenland, and includes crucial new material from southern, northeastern and northwestern Greenland. Although each date provides only a minimum age for the local deglaciation, some of the dates come from species that indicate ice-proximal glaciomarine conditions, and thus may be connected with the actual ice recession. In addition to shell dates, dates from marine algae, lake sediments, peat, terrestrial plants and driftwood also are included. Only offshore and in the far south have secure late-glacial sediments been found. Other previous reports of late-glacial sediments (older than 11.5 cal. kyr BP) from onshore parts of Greenland need to be confirmed. Most of the present ice-free parts of Greenland and Nares Strait between Greenland and Ellesmere Island were not deglaciated until the early Holocene.
