Varve Chronology, Proxy Calibration, and Holocene Climate of Minnesota
Despite the numerous Holocene paleoclimatic records from the North American continent, few existing records from the American Midwest have adequate chronological controls, marking it problematic to link regional climatic changes to possible larger-scale forcing. With solid 14C chronologies, the …

Varve and event layer chronology of Lake Suigetsu (Japan) back to 40 kyr BP and contribution to the international consensus atmospheric radiocarbon calibration curve
… intention of the PhD project was to create a varve chronology for the Suigetsu Varves 2006' (SG06) composite profile from Lake Suigetsu (Japan) by thin section microscopy. The chronology was not only to provide an age-scale for the various palaeo-environmental proxies analysed within the SG06 …

Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden
… dating and, for two of the sites, on a clay-varve chronology. The stratigraphies were correlated to the GRIP event stratigraphy and their ages are expressed in calendar years BP. The pollen records compare well to the established Late Weichselian pollen stratigraphy for southern Sweden, and …

Investigations of temporal changes in climate and the geomagnetic field via high-resolution radiocarbon dating
… applied to construct an accurate and precise chronology of the annually laminated (varved) 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 …

Setting the Holocene clock using varved lake sediments in Sweden
… of this thesis was to study annually 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 …
