Climatic signals and frequencies in the Swedish Time Scale, River Ångermanälven, Central Sweden
… into a long record of fluvial activity in Central Sweden and illuminates some of the possible forcing agent behind past (and future) discharge variation. Along the Swedish East Coast varved deposits of sand silt and clay couplets make up a chronology, which extend from the present into the …

Tree-limit ecotonal response to Holocene climate change in the Scandes Mountains of west-central Sweden
… Sylarna-Storulvån area, western Jämtland, in the central Scandes Mountains. Temporal trends and fluctuations in the elevation and vegetational character of the tree-limit ecotone were studied mainly by means of pollen and plant macrofossil analysis of two lake sediment sequences (Lakes Stentjärn …

The Ups and Downs of the Holocene: Exploring Relationships between Global CO2 and Climate Variability in the North Atlantic Region
… core measurements. Lakes sediments from south-central Sweden were collected and the analyses were focussed on a c. 1,000 year period centred at c. 4,000 cal. yr BP when an abrupt change to a cooler/wetter climate had previously been recorded. Secondly, lake sediments from the Faroe Islands …

Setting the Holocene clock using varved lake sediments in Sweden
… laminated (varved) Holocene lake sediment in Sweden, their formation and their potential as chronological and palaeoecological archives. Five lakes with continuous Holocene varved lake sediment sequences in northern (Västerbotten) and west central Sweden (Värmland) were investigated. Three of …

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating
… sediments of Lake Gyltigesjön in south-west Sweden for the period around 3000-2000 cal BP. With this technique, it was possible to estimate the old-carbon effect (14C reservoir age) in the lake sediments. The bulk sediment based chronology was validated by comparison to the 14C ages of plant …

The palaeolimnological record of regime shifts in lakes in response to climate change
… detailed diatom record from Lake Kälksjön, west-central Sweden, was investigated for periods of abrupt ecological change associated with the 8.2 ka cooling event. Using change-point analysis we found two regime shifts in the diatom record: one in response to an abrupt erosion event at c. 8040 …
