Abstract Deposits in coastal lakes northernmost Norway reveal that the Storegga tsunami propagated well into Barents Sea ca. 8100–8200 years ago. A deposit – found cores from five located near North Cape Finnmark rests on an erosional unconformity and consists of graded sand layers re‐deposited organic remains. Rip‐up clasts lake mud, peat soil suggest strong erosion floor neighbouring land. Inundation reached at least 500 m inland minimum vertical run‐up has been reconstructed to 3–4 m. In...

(RSL) mid‐Hardangerfjorden area covering entire is presented. based on a series AMS 14 C dates terrestrial plant macrofossils across isolation level in each five lakes located between 3.5 and 74.5 m a.s.l. During 1200 years, RSL fell very rapidly marine limit at 98 to...
Directly observing the chronology and tempo of adaptation in response to ecological change is rarely possible natural ecosystems. Sedimentary ancient DNA (sedaDNA) has been shown be a tractable source genome-scale data long-dead organisms1Gelabert P. Sawyer S. Bergström A. Margaryan Collin T.C. Meshveliani T.

This study discusses the timing and maximum flood level of Nedre Glomsjø outburst flood, Norway, based on sediment records retrieved from 15 bog lake basins located close to purported flooded level. The in 12 consist a distinct light‐coloured silty bed that is correlated outburst‐flood‐deposited ‘Romerike Silt Bed’ identified elsewhere region. silt recorded up certain elevation absent above this new inferred basin exceeds established landform‐induced palaeostage indicators by 5–10 m. data...
The thinning and final decay of the Scandinavian Ice Sheet in Gudbrandsdalen area central southern Norway is described, based on (1) cosmogenic 10Be surface exposure dating 25 glacially transported boulders, (2) radiocarbon plant remains basal strata four lakes (3) mapping large ice-dammed that formed at different elevations times during last deglacation. We complement new chronology with previously published 10Be-ages from same region. dated samples are spread mountain summits 1800 m a.s.l....
We report a new H olocene relative sea‐level curve based on the stratigraphy in five closely located isolation basins near L ista southernmost N orway. The results detail progress and timing of mid‐ Tapes transgression, peak which this region represents highest postglacial sea level, as well rate land emergence since then. One additional cored basin is situated above marine limit. All have bedrock sills that were levelled using differential GPS . Isolation ingression boundaries identified by...
ABSTRACT Basal records from nine lake basins, located within a small area inside the Younger Dryas Ra moraine in southern Norway, were analysed and radiocarbon dated. Six reworked shell fragments lowermost facies five different basins date to Bølling–Allerød chronozone are interpreted represent an ice‐free coastline before ice sheet readvance of at least 8 km. The widespread margin but pre‐dating demonstrated using systematic survey strata collection basins. A further 13 dated samples,...
Abstract The coastal settlement in Middle Mesolithic (MM) Southeast Norway is generally described as a dynamic system of small, short-lived sites and large that were visited repeatedly over long time. It has been suggested this period – compared to the preceding Early (EM) an increased attraction towards archipelagos along Norwegian coast, their broad spectrum both marine terrestrial food sources, took place. This has, however, debated. An important background for discussion documented...
Human impact on long-term vegetation and biodiversity changes is often discussed a general level, connecting palynological data to archaeological time periods. In the present paper we environmental change during last 2,400 years coastal peninsula in Norway using pollen from three sites: one lake two bogs, addition 621 radiocarbon dates in-context samples sites. Locally, close relationship between richness reflecting high landscape, habitat floristic diversity, summed probability distribution...
Ocean-rafted pumice is found on modern and paleo-beaches from the North Atlantic to South Pacific. Correlation of ocean-rafting events their volcanic source can help date sedimentary records landforms, while geochemical fingerprinting artefacts made ocean-rafted provides age constraints for pumice-bearing archaeological sites. These pumices also record large explosive eruptions that might not be preserved near volcano due extensive erosion or a submarine as such used petrological...
Abstract We here describe the results of stratigraphic and sedimentological examinations debris flow deposits at Breidokk, Gol, southern Norway. The are situated valley floor, below a steep slope with three large several smaller channels incised into thick till cover. study area is populated abundant infrastructure such as roads, public private buildings other types infrastructure, including underground water pipes cables. Six, 10–15 m long 1–3 deep trenches were dug out an excavator...
Parallel evolution is typically studied by comparing modern populations from contrasting environments, therefore the chronology of adaptive changes remains poorly understood. We applied a paleogenomics approach to investigate this temporal component adaptation sequencing genomes 11-13,000-year-old stickleback recovered transitionary layer between marine and freshwater sediments two Norwegian isolation lakes, them with 30 same lakes adjacent fjord. The ancient shared genome-wide ancestry...
