“…We assume therefore that, outside the northwest area, Skåne remained mostly ice‐free until about 25 kyr BP and that the first major glaciation occurred at the time of the LGM‐stadial II of Denmark. This advance appears to have covered most of Skåne with tills in the central, northern and southwestern regions, all apparently corresponding to the same till sheet (Ringberg 1988). These deposits occur up to 200 m above present sea level in northwestern Skåne, corresponding to the highest elevations of the area, and this provides a minimum estimate of the ice thickness at this time. LGM‐stadial III.…”

“…This is consistent with evidence from Denmark, where the LGM‐stadial III advance had a more northerly direction than the preceding advance. Thus we interpret the upper till layers (the Hässleholm, Hardeberga, Malmö and related tills of Ringberg 1988) as corresponding to the LGM‐stadial III advance. LGM‐interstadials II and III. Based on the absence of the above‐mentioned sands/clays/gravel layers in cores from the northern and northeastern locations (Ringberg 1988; Ringberg & Miller 1992), we assume that western and southern Skåne was briefly ice‐free during LGM‐interstadial II.…”

“…The post‐Gärdslöv tills span an age interval of about 7000–8000 years, with a possible brief period in which sediments consisting of sands, clays and gravels were deposited during ice‐free conditions. Below this ‘ice‐free’ layer the erratics within the tills are mainly of Baltic origin, but above it they, and accompanying ice‐flow directional markers, are indicative of the ice coming from a more northerly direction (Ringberg 1988; Ringberg & Miller 1992). This is consistent with evidence from Denmark, where the LGM‐stadial III advance had a more northerly direction than the preceding advance.…”

The tills overlying the LGM‐interstadial II do indicate a short‐duration interruption in the glaciation of southwest Skåne (Ringberg 1988; Ringberg & Miller 1992), which is assumed to correspond to the period of ice retreat seen in Denmark and denoted as LGM‐interglacial III. It is not seen in central Skåne, and the limit of the retreat is placed to the east of Dalby (56.7°N, 13.3°E). LGM‐stadial IV.…”

Glacial rebound modelling, to establish constraints on past ice sheets from the observational evidence of palaeoshoreline elevations, is well established for the post-Last Glacial Maximum (post-LGM) period, for which the observational evidence is relatively abundant and well distributed spatially and in time. This is particularly the case for Scandinavia. For the earlier part of the glacial cycle this evidence becomes increasingly sparse and uncertain such that, with the exception of the Eemian period, there are very few, if any, direct sea-level indicators that constrain any part of the Scandinavian Ice Sheet evolution before the LGM. Instead, we assume that ice-sheet basal conditions during Marine Isotope Stage 3 (MIS 3) are the same as those for the LGM, focus on establishing these conditions from the rebound analysis for the LGM and Lateglacial period, and then extrapolate to the earlier period using observationally constrained locations of the ice margins. The glacial rebound modelling and inversion follow previously established formulations, with the exception that the effects of water loading from proglacial lakes that form within the Baltic Basin and elsewhere have been included. The data set for the inversion of the seaand lake-level data has been extended to include marine-limit data in order to extend the observational record further back in time. The result is a sequence of time slices for the Scandinavian Ice Sheet from the time of MIS 4 to the Lateglacial that are characterized by frozen basal conditions until late in the LGM interval when rapid thinning occurred in the eastern and southern sectors of the ice sheet. The primary function of these models is as an interpolator between the fragmentary observational constraints and to produce quantitative models for the glaciation history with predictive capabilities, for example regarding the evolution of the Baltic Basin.

“…The Baltic basin was deglaciated between c. 13 500 and 13 000 (Berglund 1979;Lagerlund 1987;Ringberg 1988) and 9000 14 C yr BP (Andrén 1990). Ever since the deglaciation, the interaction between the isostatic rebound and eustatic sea level changes has governed the subsequent development of the Baltic Sea.…”

Evidence of the final drainage of the Baltic Ice Lake and the brackish phase of the Yoldia Sea in glacial varves from the Baltic Sea

A clay‐varve chronology based on 14 cross‐correlated varve graphs from the Baltic Sea and a mean varve thickness curve has been constructed. This chronology is correlated with the Swedish Time Scale and covers the time span 11 530 to 10250 varve years BP. Two cores have been analysed for grain size, chemistry, content of diatoms and changes in colour by digital colour analysis. The final drainage of the Baltic Ice Lake is dated to c. 10800 varve years BP and registered in the cores analysed as a decrease in the content of clay. This event can be correlated with atmospheric Δ14C content and might have resulted in an increase in these values recorded between 11 565 and 11 545 years BP. The results of the correlation between the varve chronology from the Baltic Sea, the Greenland GRIP ice core and the atmospheric Δ14C record indicate that c. 760 years are missing in the Swedish Time Scale in the part younger than c. 10250 varve years BP. A change in colour from a brownish to grey varved glacial clay recorded c. 10770 varve years BP is found to be the result of oxygen deficiency due to an increase in the rate of sedimentation in the early Preboreal. The first brackish influence is recorded c. 10540 varve years BP in the northwestern Baltic Sea and some 90 years later in the eastern Gotland Basin.

A synthesis is presented of the environmental and climatic variations that are inferred to have occurred in southern Sweden (up to latitude 59"N) and Denmark during the Weichselian Late-glacial (1 4-9 kaBP). The chronology and characteristics of the main phases of deglaciation, sea-level change, periglacial activity, soil development, vegetation cover and climate change are summarised. A curve representing the main changes in temperature, including quantitative estimates based upon beetle data and using the 'mutual climatic range' method, is presented.Journal of Quaternary Science
