    • The First International Conference on 'Processes and Palaeo-Environmental Changes in the Arctic: From Past to Present' (PalaeoArc) 

      Lyså, Astrid; Benediktsson, Ívar Örn; Emery, Andy; Gregoire, Lauren; Jennings, Anne; Morigi, Caterina; Müller, Juliane; O'Regan, Matt; Sarala, Pertti; Stokes, Chris; Szczuciński, Witold; Winsborrow, Monica (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-13)
      The new international network PalaeoArc (Processes and Palaeo Environmental Changes in the Arctic: From Past to Present) held its first meeting in Poznan, 20-24 May 2019. The meeting was hosted by the Faculty of Geographical and Geological Sciences, Adam Mickiewicz University, Poznan, and organized by a local committee chaired by Witold Szczuciński.

    • Fossil organic carbon utilization in marine Arctic fjord sediments by subsurface micro-organisms 

      Ruben, Manuel; Hefter, Jens; Schubotz, Florence; Geibert, Walter; Butzin, Martin; Gentz, Torben; Grotheer, Hendrik; Forwick, Matthias; Szczuciński, Witold; Mollenhauer, Gesine (Journal article; Tidsskriftartikkel, 2023)
      Rock-derived or petrogenic organic carbon has traditionally been regarded as being non-bioavailable and bypassing the active carbon cycle when eroded. However, it has become apparent that this organic carbon might not be so inert, especially in fjord systems where petrogenic organic carbon influxes can be high, making its degradation another potential source of greenhouse gas emissions. The extent ...

    • The influence of Coriolis force driven water circulation on the palaeoenvironment of Hornsund (S Spitsbergen) over the last century 

      Pawłowska, Joanna; Zajączkowski, Marek; Szczuciński, Witold; Zaborska, Agata; Kucharska, Małgorzata; Jernas, Patrycja Ewa; Forwick, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-22)
      The influence of the Coriolis force on the Hornsund fjord environment (southern Spitsbergen) was investigated in the marine sedimentary record from the last century. Due to the influence of the rotational effects, Atlantic and Arctic Water enter the fjord along the southern shore and exit along the northern shore. Thus, the sedimentary record from the southern part reflects the large‐scale hydrological ...

    • Multiproxy paleoceanographic study from the western Barents Sea reveals dramatic Younger Dryas onset followed by oscillatory warming trend 

      Łącka, Magdalena; Michalska, Danuta; Pawłowska, Joanna; Szymańska, Natalia; Szczuciński, Witold; Forwick, Matthias; Zajączkowski, Marek (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-24)
      The Younger Dryas (YD) is recognized as a cool period that began and ended abruptly during a time of general warming at the end of the last glacial. New multi-proxy data from a sediment gravity core from Storfjordrenna (western Barents Sea, 253 m water depth) reveals that the onset of the YD occurred as a single short-lived dramatic environment deterioration, whereas the subsequent warming was ...

    • Neodymium isotope constraints on chemical weathering and past glacial activity in Svalbard 

      Jang, Kwangchul; Bayon, Germain; Han, Yeongcheol; Joo, Young Ji; Kim, Ji-Hoon; Ryu, Jong-Sik; Woo, Jusun; Forwick, Matthias; Szczuciński, Witold; Kim, Jung-Hyun; Nam, Seung-Il (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-15)
      <p>Neodymium (Nd) isotopes in leached authigenic components of marine sediments have been increasingly used as a tracer of past ocean-water masses. Despite the general assumption that the Nd isotopic composition of solutes released during chemical weathering fingerprints the source rocks on continents, preferential dissolution of easily dissolvable phases may result in significant deviations in Nd ...
