“…Throughout Europe, there have been notable successes in extracting detailed climateproxy data from varved records from the Last Glacial to Interglacial transition (LGIT: ca. 16-8 ka; De Geer, 1940;Brunnberg, 1995;Lotter, 1991;Andrén et al, 1999;Brauer et al, 1999;Litt et al, 2001;Lundqvist and Wohlfarth, 2001;Hang, 2003;Ringberg et al, 2003;Johnson et al, 2013;Lane et al, 2013). However, many of these records are not varved to the present day and often those that are have substantial counting uncertainties associated with them, or potential problems of 'missing years'.…”

Here we present a 710-year-long floating varve record from south-east Sweden. Tephra analyses confirm the presence of the rhyolitic Vedde Ash preserved within two consecutive varve years, confirming the Younger Dryas age of the varve series. This permits, for the first time, direct correlation of Swedish varved clay with other records of equivalent resolution which also preserve the Vedde Ash and demonstrates that the potential exists to independently date the Swedish Timescale. This discovery will allow direct comparison of rates, timing and duration of key climatic events across Europe and the North Atlantic region in records of equivalent resolution.

Varved sequences from Germany, Poland and Scandinavia, for example, have been compared to the GRIP ice core records (Andren et al, 1999;Litt et al, 2001;Ringberg et al, 2003) with a precision not achievable for most other sedimentary archives (Blockley et al, 2007;Lowe et al, 2008). Detailed study of the sedimentological characteristics and structure of glaciolacustrine varves can also provide insights into the character and duration of past catchment properties and variations in sediment supply (Smith, 1978;Leonard, 1986Leonard, , 1997Desloges, 1994;Lamoureux, 1999;Hughen et al, 2000;Lamoureux et al, 2001).…”

This paper presents the results of micromorphological analysis of laminated sediments that accumulated in ice-dammed lakes in Lochaber (Glen Roy and vicinity) during the Younger Dryas (Loch Lomond) Stadial. These lakes were responsible for the formation of the famous 'Parallel Roads of Glen Roy' (Agassiz, 1840), prominent shorelines cut into the valley sides of Glen Roy and adjacent valleys. Annually deposited (varved) layers, which can be distinguished from other rhythmites by micromorphological examination, have enabled the construction of a varve chronology which underpins the glacial history of the region, the duration of the lake stands and rates of ice margin advance and retreat. The lake system existed for a total of 515 a. During a rise in lake levels, the lowermost (260 m), middle (325 m) and highest (350 m) lakes existed for minimal periods of 191, 112 and 116 a, respectively, and the fall of lake levels from 350 m to 260 m took 95 years. Ice advance rates of between 13.4 and 41.9 m a À1 are inferred, while ice retreat is estimated to have been $38.5 m a À1 . A provisional correlation between the Lochaber varve and GRIP ice core records suggests that the lakes started to form at ca. 12 165 a BP, in turn implying that the Loch Lomond Readvance limits in this area were not achieved until late in the Younger Dryas interval, a conclusion which does not accord with that based on numerical model simulations.

“…However, there is a time-lag between the other changes in the colour and in pollen cycles. Such shifts were also observed by Ringberg et al (2003) between the accumulation of thick varves and the change to a "warmer" pollen flora. Such a correlation illustrates a relationship between the short-term climatic fluctuations inferred from variations in lamina thickness (colour cycles) and the varying pollen composition, which reflect cooler/warmer and drier/wetter periods.…”

“…The authors concluded that the dark laminae were deposited during winter-early spring and the light laminae during late spring-summer. Ringberg et al (2003) also demonstrated that variations in lamina thickness reflecting colder and warmer periods corresponded to varying pollen composition in the varves with colder pollen flora in thin varves and warmer pollen flora in thick varves.…”
