    • Benthic foraminifera in an Arctic fjord : recent distribution and fauna of the last two millennia 

      Jernas, Patrycja Ewa (Doctoral thesis; Doktorgradsavhandling, 2012-09-13)
      The main objective of the PhD study was to improve the knowledge about the ecology of the benthic foraminiferal faunas thus increasing the precision of benthic foraminifera as indicators for modern and past Arctic fjord and shelf environments. The investigation of living (stained) benthic foraminifera assemblages in Kongsfjorden (western Svalbard) was performed on inter-annual and seasonal time ...

    • 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 ...

    • Limited grounding-line advance onto the West Antarctic continental shelf in the easternmost Amundsen Sea Embayment during the last glacial period 

      Klages, Johann Philipp; Kuhn, Gerhard; Hillenbrand, Claus-Dieter; Smith, James; Graham, Alastair G C; Nitsche, F. O.; Frederichs, Thomas; Jernas, Patrycja Ewa; Gohl, Karsten; Wacker, Lukas (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-25)
      Precise knowledge about the extent of the West Antarctic Ice Sheet (WAIS) at the Last Glacial Maximum (LGM; c. 26.5–19 cal. ka BP) is important in order to 1) improve paleo-ice sheet reconstructions, 2) provide a robust empirical framework for calibrating paleo-ice sheet models, and 3) locate potential shelf refugia for Antarctic benthos during the last glacial period. However, reliable reconstructions ...

    • Nordic Seas polynyas and their role in preconditioning marine productivity during the Last Glacial Maximum 

      Knies, Jochen; Koseoglu, Denizcan; Rise, Leif; Baeten, Nicole; Bellec, Valerie K; Bøe, Reidulv; Klug, Martin; Panieri, Giuliana; Jernas, Patrycja Ewa; Belt, Simon T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-27)
      Arctic and Antarctic polynyas are crucial sites for deep-water formation, which helps sustain global ocean circulation. During glacial times, the occurrence of polynyas proximal to expansive ice sheets in both hemispheres has been proposed to explain limited ocean ventilation and a habitat requirement for marine and higher-trophic terrestrial fauna. Nonetheless, their existence remains equivocal, ...
