    • Arctic Paleoceanography Cruise KH21-234 with R/V Kronprins Haakon 

      De Schepper, Stijn; Larsen, Aud; Blindheim, Dag Inge; Cordier, Tristan; Grant, Danielle; Hestetun, Jon Thomassen; Häkli, Katja; Lefevere, Simon Pierre; Liltved, Allegra; Monsen, Stig; Mugu, Sigrid; Ray, Jessica Louise; Steinsland, Kristine; Trofimova, Tamara; Weiner, Agnes (Research report, 2022)
      We set sail from Longyearbyen on 30.6.2021 to collect surface sediments, long sediment archives, water and plankton samples. The study area is located north of Svalbard, within the seasonal and permanent sea ice covered ...

    • Flow Cytometric Analysis of Bacterial Protein Synthesis: Monitoring Vitality After Water Treatment 

      Lindivat, Mathilde; Bratbak, Gunnar; Larsen, Aud; Hess-Erga, Ole-Kristian; Hoell, Ingunn Alne (Peer reviewed; Journal article, 2021)
      Bacterial vitality after water disinfection treatment was investigated using bio-orthogonal non-canonical amino acid tagging (BONCAT) and flow cytometry (FCM). Protein synthesis activity and DNA integrity (BONCAT–SYBR ...

    • High CO2 concentration and iron availability determine the metabolic inventory in an Emiliania huxleyi-dominated phytoplankton community 

      Mausz, Michaela A.; Segovia, María; Larsen, Aud; Berger, Stella Angela; Egge, Jorun Karin; Pohnert, Georg (Journal article; Peer reviewed, 2020)
      Ocean acidification (OA), a consequence of anthropogenic carbon dioxide (CO2) emissions, strongly impacts marine ecosystems. OA also influences iron (Fe) solubility, affecting biogeochemical and ecological processes. We ...

    • How microbial food web interactions shape the arctic ocean bacterial community revealed by size fractionation experiments 

      Müller, Oliver; Seuthe, Lena; Pree, Bernadette; Bratbak, Gunnar; Larsen, Aud; Paulsen, Maria Lund (Journal article; Peer reviewed, 2021)
      In the Arctic, seasonal changes are substantial, and as a result, the marine bacterial community composition and functions differ greatly between the dark winter and light-intensive summer. While light availability is, ...

    • Kunnskapsstatus for bruk av molekylære verktøy i kartlegging og overvåkning av biologisk mangfold i marine miljø 

      Dunshea, Glenn; Martell, Luis; Bakken, Torkild; Budaeva, Nataliya; Ekrem, Torbjørn; Tandberg, Anne Helene S.; Baussant, Thierry; de Boer, Hugo; Hestetun, Jon Thomassen; Hobæk, Anders; Kallioniemi, Eveliina; Larsen, Aud; Markussen, Stine Svalheim; Mauvisseau, Quentin; Ray, Jessica Louise; Yoccoz, Nigel; Willassen, Endre (Research report, 2021)
      Denne rapporten er bestilt av Miljødirektoratet fra NorBOL (Norwegian Barcode of Life), et nasjonalt nettverk av forskningsinstitusjoner som koordineres av NTNU Vitenskapsmuseet. Universitetsmuseet i Bergen har hatt ...

    • MetaMon final project report - High-throughput metabarcoding of eukaryotic diversity for environmental monitoring of marine sediments 

      Hestetun, Jon Thomassen; Lanzén, Anders; Bagi, Andrea; Ray, Jessica Louise; Larsen, Aud; Dahlgren, Thomas Gunnar (Research report, 2021)
      MetaMon (2018-2021) was a project at the NORCE Molecular Ecology Research Group aimed at maturing eDNA for sediment offshore environmental monitoring. Findings include (i) guidelines for sampling and processing, (ii) a 97 ...

    • The Possession of Coccoliths Fails to Deter Microzooplankton Grazers 

      Mayers, Kyle; Poulton, Alex J.; Bidle, Kay D.; Thamatrakoln, Kimberlee; Schieler, Brittany; Giering, Sarah L.C.; Wells, Seona R.; Tarran, Glen A.; Mayor, Dan; Johnson, Matthew; Riebesell, Ulf; Larsen, Aud; Vardi, Assaf; Harvey, Elizabeth L. (Peer reviewed; Journal article, 2020)
      Phytoplankton play a central role in the regulation of global carbon and nutrient cycles, forming the basis of the marine food webs. A group of biogeochemically important phytoplankton, the coccolithophores, produce calcium ...

    • Removal of large viruses and their dispersal through fecal pellets of the appendicularian Oikopleura dioica during Emiliania huxleyi bloom conditions 

      Mayers, Kyle; Lawrence, Janice; Skaar, Katrine Sandnes; Töpper, Joachim Paul; Petelenz-Kurdziel, Elzbieta Anna; Saltvedt, Marius Rydningen; Sandaa, Ruth-Anne; Larsen, Aud; Bratbak, Gunnar; Ray, Jessica Louise (Peer reviewed; Journal article, 2021)
      Despite their importance in shaping the structure and function of marine microbial food webs, little is known about factors regulating marine virus abundance. Previous work demonstrated clearance of laboratory-cultured ...

    • Viral infection switches the balance between bacterial and eukaryotic recyclers of organic matter during coccolithophore blooms 

      Vincent, Flora; Gralka, Matti; Schleyer, Guy; Schatz, Daniella; Cabrera-Brufau, Miguel; Kuhlisch, Constanze; Sichert, Andreas; Vidal-Melgosa, Silvia; Mayers, Kyle; Barak-Gavish, Noa; Flores, J. Michel; Masdeu-Navarro, Marta; Egge, Jorun Karin; Larsen, Aud; Hehemann, Jan-Hendrik; Marrasé, Celia; Simó, Rafel; Cordero, Otto X.; Vardi, Assaf (Peer reviewed; Journal article, 2023)
      Algal blooms are hotspots of marine primary production and play central roles in microbial ecology and global elemental cycling. Upon demise of the bloom, organic carbon is partly respired and partly transferred to either ...
