2500 years of anthropogenic and climatic landscape transformation in the Stymphalia polje, Greece
Seguin, Joana; Bintliff, John L; Grootes, Pieter Meiert; Bauersachs, Thorsten; Dörfler, Walter; Heymann, Christian; Manning, Sturt W.; Müller, Samuel; Nadeau, Marie-Josée; Nelle, Oliver; Steier, Peter; Weber, Jan; Wild, Eva-Maria; Zagana, Eleni; Unkel, Ingmar (Peer reviewed; Journal article, 2019)Lacustrine sediments generally record landscape development in the lake's catchment area controlled by palaeoclimatic and human induced changes. To improve our understanding on the anthropogenic and climatic influences on ... -
A Whale as Old as Time
Sikström, Fanny (Master thesis, 2023)Dette prosjektet har som hensikt å demonstrere relevansen av å datere hvalbein fra arkeologisk kontekst og viktigheten av å benytte en artsspesifikk ∆R. Samt teste teorien at proteinet og fettet fra hvalbein vil gi ulike ... -
A dated volcano-tectonic deformation event in Jan Mayen causing landlocking of Arctic charr
Larsen, Eiliv; Lyså, Astrid; Höskuldsson, Ármann; Davidsen, Jan Grimsrud; Nadeau, Marie-Josée; Power, Michael; Tassis, Georgios; Wastegård, Stefan (Peer reviewed; Journal article, 2021)We provide the first documentation of tectonic deformation resulting from a volcanic eruption on the island of Jan Mayen. Vertical displacement of about 14 m southwest of the stratovolcano Beerenberg is associated with an ... -
Earthworms, Darwin and prehistoric agriculture-Chernozem genesis reconsidered
Dreibrodt, Stefan; Hofmann, Robert; Dal Corso, Marta; Bork, Hans-Rudolf; Duttmann, Rainer; Martini, Sarah J.; Saggau, Philipp; Schwark, Lorenz; Shatilo, Liudmyla; Videiko, Michail; Nadeau, Marie-Josée; Grootes, Pieter Meiert; Kirleis, Wiebke; Müller, Johannes (Peer reviewed; Journal article, 2021)Chernozems are among the most fertile agricultural soils on Earth and are important terrestrial carbon reservoirs. Since the Miocene-advent of grassland-ecosystems, they develop on fine-grained calcareous parent materials, ... -
Findings from an in-Depth Annual Tree-Ring Radiocarbon Intercomparison
Wacker, Lukas; Scott, Ethel Marian; Bayliss, Alex; Brown, David; Bard, Édouard; Bollhalder, Silvia; Friedrich, Michael; Capano, Manuela; Cherkinsky, Alexander; Chivall, David; Culleton, Brendan J.; Dee, Michael W; Friedrich, Ronny; Hodgins, Gregory W.L.; Hogg, Alan G.; Kennett, Douglas J.; Knowles, Timothy D.; Kuitems, Margot; Lange, Todd E.; Miyake, Fusa; Nadeau, Marie-Josée; Nakamura, Toshio; Naysmith, J.P.; Olsen, Jesper; Omori, Toshihiko; Petchey, Fiona; Philippsen, Bente; Ramsey, Christopher Bronk; Prasad, G.V.A.; Seiler, Martin; Southon, John; Staff, Richard A.; Tuna, Thibaut (Peer reviewed; Journal article, 2020)The radiocarbon (14C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to ... -
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 ... -
Quaternary landscape evolution in a tectonically active rift basin (paleo-lake Mweru, south-central Africa)

Radiocarbon calibration around AD 1900 from Scots pine (Pinus sylvestris) tree rings from northern Norway
Svarva, Helene Løvstrand; Grootes, Pieter Meiert; Seiler, Martin; Thun, Terje; Værnes, Einar; Nadeau, Marie-Josée (Journal article; Peer reviewed, 2019)To resolve an inconsistency around AD 1895 between radiocarbon (14C) measurements on oak from the British Isles and Douglas fir and Sitka spruce from the Pacific Northwest, USA, we measured the 14C content in single-year ... -
Status Report of the Trondheim Radiocarbon Laboratory
Seiler, Martin; Grootes, Pieter Meiert; Haarsaker, John Øystein; Lelu, Sylvie; Rzadeczka-Juga, Izabela; Stene, Sølvi; Svarva, Helene Løvstrand; Thun, Terje; Værnes, Einar; Nadeau, Marie-Josée (Journal article; Peer reviewed, 2019)The Trondheim radiocarbon (14C) laboratory has evolved from a traditional radiocarbon decay counting laboratory to an accelerator mass spectrometry (AMS) facility primarily measuring 14C. This evolution required adjustments ... -
The 1953-1965 rise in atmospheric bomb 14C in central Norway
Svarva, Helene Løvstrand; Grootes, Pieter Meiert; Seiler, Martin; Stene, Sølvi; Thun, Terje; Værnes, Einar; Nadeau, Marie-Josée (Journal article; Peer reviewed, 2019)Sub-annual measurements, eight increments per year, of cellulose in a Scots pine tree growing in central Norway are presented as a proxy for tropospheric 14CO2 at biweekly to monthly resolution. The results are validated ...
