    • Late Quaternary terrigenous plant and coaly fragments found at Vestnesa Ridge, Fram Strait: implications for postglacial plant colonization at Svalbard 

      Hanken, Nils-Martin; Sztybor, Kamila; Høeg, Helge I.; Karlsen, Dag Arild; Rasmussen, Tine Lander; Abay, Tesfamariam Berhane (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-23)
      One of four marine cores of glacial sediments collected from a water depth of about 1200 m at Vestnesa Ridge (west of Svalbard) contained small fragments of coal, charcoal and moss. This material was restricted to a single level, and 14C dating of bivalves both above and below indicates an age of c. 18.0–15.5 kyr BP. Chemical analyses of the coal indicate that the provenance area was from the northern ...

    • Paleoeconomy more than demography determined prehistoric human impact in Arctic Norway 

      Brown, Antony; Rijal, Dilli Prasad; Heintzman, Peter D.; Clarke, Charlotte, L.; Blankholm, Hans Peter; Høeg, Helge I.; Lammers, Youri; Bråthen, Kari Anne; Edwards, M E; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-07)
      Population size has increasingly been taken as the driver of past human environmental impact worldwide, and particularly in the Arctic. However, sedimentary ancient DNA (sedaDNA), pollen and archaeological data show that over the last 12,000 years, paleoeconomy and culture determined human impacts on the terrestrial ecology of Arctic Norway. The large Mortensnes site complex (Ceavccagea ¯dgi, 70◦N) ...
