10Be surface exposure dating of the deglaciation of northernmost Norway and Finland
Anjar, Johanna; Akçar, Naki; Lakeman, Thomas; Larsen, Eiliv; Seiler, Martin (Peer reviewed; Journal article, 2020)During the Last Glacial Maximum, the coast of Finnmark county, northern Norway, was covered by the Scandinavian Ice Sheet (SIS), which coalesced with the Barents Sea Ice Sheet (BSIS) off the coast. The region is thus ... -
Cosmogenic exposure dating (36Cl) of landforms on Jan Mayen, North Atlantic, and the effects of bedrock formation age assumptions on 36Cl ages
Anjar, Johanna; Akҫar, Naki; Larsen, Eiliv A.; Lyså, Astrid; Marrero, Shasta; Mozafari, Nasim; Vockenhuber, Christof (Peer reviewed; Journal article, 2021)Jan Mayen is a small volcanic island situated 550 km north of Iceland. Glacial sediments and landforms are relatively common on the island but, so far, only a few of them have been dated. In this study, we present and ... -
Data set on sedimentology, palaeoecology and chronology of Middle to Late Pleistocene deposits on the Taimyr Peninsula, Arctic Russia
Möller, Per; Benediktsson, Ívar Örn; Anjar, Johanna; Bennike, Ole; Bernhardson, Martin; Funder, Svend; Håkansson, Lena; Lemdahl, Geoffrey; Licciardi, Joseph M.; Murray, Andrew S.; Seidenkrantz, Marit-Solveig (Peer reviewed; Journal article, 2019)This Data in Brief paper contains data (including images) from Quaternary sedimentary successions investigated along the Bol'shaya Balakhnya River and the Luktakh–Upper Taimyra–Logata river system on southern Taimyr ... -
First 10Be measurements at Trondheim 1 MV AMS
Seiler, Martin; Anjar, Johanna; Værnes, Einar; Nadeau, Marie-Josée; Scognamiglio, Grazia (Journal article; Peer reviewed, 2018)The performance of the Trondheim 1 MV AMS system for 10Be measurements has been investigated. While the initial acceptance tests were done using the 1 + 1+ charge state, we concluded that the 2 + 2+ charge state offers ... -
Glacial history and palaeo-environmental change of southern Taimyr Peninsula, Arctic Russia, during the Middle and Late Pleistocene
Möller, Per; Benediktsson, Ívar Örn; Anjar, Johanna; Bennike, Ole; Bernhardson, Martin; Funder, Svend; Håkansson, Lena; Lemdahl, Geoffrey; Licciardi, Joseph M.; Murray, Andrew S.; Seidenkrantz, Marit-Solveig (Peer reviewed; Journal article, 2019)We here reconstruct a glacial and climate history of arctic NW Siberia for the last ~600,000 years, based on the stratigraphy and chronology of 35 studied river sections on the southern Taimyr Peninsula. From this stratigraphic ... -
The last glaciation of the Arctic volcanic island Jan Mayen
Lyså, Astrid; Larsen, Eiliv; Anjar, Johanna; Akçar, Naki; Ganerød, Morgan; Hiksdal, Asbjørn; van der Lelij, Roelant; Vockenhuber, Christof (Peer reviewed; Journal article, 2020)The volcanic island of Jan Mayen, remotely located in the Norwegian‐Greenland Sea, was covered by a contiguous ice cap during the Late Weichselian. Until now, it has been disputed whether parts of the island south of the ... -
MIS 3 sediment stratigraphy in southern Sweden sheds new light on the complex glacial history and dynamics across southern Scandinavia
Möller, Per; Alexanderson, Helena; Anjar, Johanna; Björck, Svante (Peer reviewed; Journal article, 2020)Recent studies have revealed that areas with sediments pre‐dating the Last Glacial Maximum (LGM) are more common in southern Scandinavia than previously thought. To describe and date these sediments, four deep core drillings ... -
OSL dating of Weichselian ice-free periods at Skorgenes, Western Norway
Anjar, Johanna; Alexanderson, Helena; Larsen, Eiliv; Lyså, Astrid (Journal article; Peer reviewed, 2018)During recent years, many sites with sediments pre-dating the Last Glacial Maximum have been identified in formerly glaciated areas. As more and better dates are presented from these sites, the dynamic behaviour of the ...
