    • A model study of the seasonal and long-term North Atlantic surface pCO(2) variability 

      Tjiputra, Jerry; Olsen, Are; Assmann, Karen Margarete; Pfeil, Benjamin; Heinze, Christoph (Journal article; Peer reviewed, 2012)
      A coupled biogeochemical-physical ocean model is used to study the seasonal and long–term variations of surface pCO2 in the North Atlantic Ocean. The model agrees well with recent underway pCO2 observations from the Surface ...

J.; Weiss, R.; Wong, CS.; Yoshikawa-Inoue, H. (Journal article; Peer reviewed, 2013)
      Abstract. A well-documented, publicly available, global data set of surface ocean carbon dioxide (CO2) parameters has been called for by international groups for nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) ...

    • Acidification of the Nordic Seas 

      Fransner, Sara Filippa Krusmynta; Fröb, Friederike; Tjiputra, Jerry; Goris, Nadine; Lauvset, Siv Kari; Skjelvan, Ingunn; Jeansson, Emil; Omar, Abdirahman; Chierici, Melissa; Jones, Elizabeth Marie; Fransson, Agneta; Olafsdóttir, Solveig R.; Johannessen, Truls; Olsen, Are (Peer reviewed; Journal article, 2022)
      Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ...

      Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a ...

    • An along-track Biogeochemical Argo modelling framework: a case study of model improvements for the Nordic seas 

      Yumruktepe, Veli Çağlar; Mousing, Erik Askov; Tjiputra, Jerry; Samuelsen, Annette (Peer reviewed; Journal article, 2023)
      We present a framework that links in situ observations from the Biogeochemical Argo (BGC-Argo) array to biogeochemical models. The framework minimizes the technical effort required to construct a Lagrangian-type 1D modelling ...

    • An update to the Surface Ocean CO2 Atlas (SOCAT version 2) 

      Bakker, Dorothee C.E.; Pfeil, Benjamin; Olsen, Are; Chierici, Melissa; Fransson, Agneta; Johannessen, Truls; Lauvset, Siv Kari; Skjelvan, Ingunn; Tjiputra, Jerry (Journal article; Peer reviewed, 2014)

    • Key physical processes and their model representation for projecting climate impacts on subarctic Atlantic net primary production: A synthesis 

      Myksvoll, Mari Skuggedal; Sandø, Anne Britt; Tjiputra, Jerry; Samuelsen, Annette; Yumruktepe, Veli Caglar; Li, Camille; Mousing, Erik Askov; Bettencourt, Joao P.H.; Ottersen, Geir (Peer reviewed; Journal article, 2023)
      Oceanic net primary production forms the foundation of marine ecosystems. Understanding the impact of climate change on primary production is therefore critical and we rely on Earth System Models to project future changes. ...

      Tjiputra, Jerry; Schwinger, Jörg; Bentsen, Mats; Morée, Anne; Gao, Shuang; Bethke, Ingo; Heinze, Christoph; Goris, Nadine; Gupta, Alok Kumar; He, Yan-Chun; Oliviè, Dirk Jan Leo; Seland, Øyvind; Schulz, Michael (Peer reviewed; Journal article, 2020)
      The ocean carbon cycle is a key player in the climate system through its role in regulating the atmospheric carbon dioxide concentration and other processes that alter the Earth's radiative balance. In the second version ...

    • Riverine impact on future projections of marine primary production and carbon uptake

      Riverine transport of nutrients and carbon from inland waters to the coastal and finally the open ocean alters marine primary production (PP) and carbon (C) uptake regionally and globally. So far, this process has not been ...
