    • Postglacial paleoceanography of the western Barents Sea: Implications for alkenone-based sea surface temperatures and primary productivity 

      Lacka, Magdalena; Cao, Min; Rosell-Melé, Antoni; Pawlowska, Joanna; Kucharska, Małgorzata; Forwick, Matthias; Zajaczkowski, Marek (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-11)
      The increasing influence of Atlantic Water (AW) in the Barents Sea, a process known as “Atlantification”, is gradually decreasing sea ice cover in the region. Ongoing global climate warming is likely to be one of its drivers, but to further understand the role of natural variability and the biogeochemical impacts of the inflow of AW into the western Barents Sea, we reconstructed sea surface temperatures ...

    • Response of benthic foraminifera to environmental successions of cold seeps from Vestnesa Ridge, Svalbard: Implications for interpretations of paleo-seepage environments 

      Melaniuk, Katarzyna; Sztybor, Kamila; Treude, Tina; Sommer, Stefan; Zajaczkowski, Marek; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-15)
      This paper presents the results of a study on the response of living benthic foraminifera to progressing environmental successions in a cold-seep ecosystem. Sediment samples were collected from Vestnesa Ridge (79°N, Fram Strait) at ~1200 m water depth. The distribution of live (Rose Bengal-stained) foraminifera were analyzed in the upper sediment layers in relation to pore water biogeochemical data ...

    • Seasonal variability of meio- and macrobenthic standing stocks and diversity in an Arctic fjord (Adventfjorden, Spitsbergen) 

      Pawlowska, J.; Wlodarska-Kowalczuk, Maria; Zajaczkowski, Marek; Nygård, Henrik Andreas; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Strong environmental seasonality is a basic feature of the Arctic system, still there are few published records of the seasonal variability of the Arctic marine biota. This study examined the year-round seasonal changes of soft bottom macro- and meiobenthic standing stocks and diversity on a station located in an Arctic fjord (Adventfjorden, Spitsbergen). The seasonality observed in benthic biota ...

    • Seasonality of occurrence and recruitment of Arctic marine benthic invertebrate larvae in relation to environmental variables 

      Kuklinski, Piotr; Berge, Jørgen; McFadden, Laurel; Dmoch, Katarzyna; Zajaczkowski, Marek; Nygård, Henrik Andreas; Piwosz, Kasia; Tatarek, Agnieszka (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      The Arctic system is one of the regions most influenced by ongoing global climate change, but there are still critical gaps in our knowledge regarding a substantial number of biological processes. This is especially true for processes taking place during the Arctic winter but also for seasonal processes, such as the dynamics of intra-annual meroplankton occurrence. Here, we report on a ...
