• A Regime View of ENSO Flavors Through Clustering in CMIP6 Models 

      Ayar, Pradeebane Vaittinada; Battisti, David Stephen; Li, Camille; King, Martin; Vrac, Mathieu; Tjiputra, Jerry (Journal article; Peer reviewed, 2023)
      El Niño-Southern Oscillation (ENSO) flavors in the tropical Pacific are studied from a regime perspective. Five recurring spatial patterns or regimes characterizing the diversity of ENSO are established using a clustering ...
    • The response of permafrost and high latitude ecosystems under large scale stratospheric aerosol injection and its termination 

      Lee, Hanna; Ekici, Altug; Tjiputra, Jerry; Muri, Helene; Chadburn, Sarah E.; Lawrence, David M.; Schwinger, Jörg (Peer reviewed; Journal article, 2019-04-15)
      Climate engineering arises as one of the potential methods that could contribute to meeting the 1.5oC global warming target agreed under the Paris Agreement. We examine how permafrost and high latitude vegetation respond ...
    • Riverine impact on future projections of marine primary production and carbon uptake 

      Gao, Shuang; Schwinger, Jörg; Tjiputra, Jerry; Bethke, Ingo; Hartmann, Jens; Mayorga, Emilio; Heinze, Christoph (Journal article; Peer reviewed, 2023)
      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 ...
    • Role of volcanic forcing on future global carbon cycle 

      Tjiputra, Jerry; Otterå, Odd Helge (Peer reviewed; Journal article, 2011-06-16)
      Using a fully coupled global climate-carbon cycle model, we assess the potential role of volcanic eruptions on future projection of climate change and its associated carbon cycle feedback. The volcanic-like forcings are ...
    • Trends and drivers in global surface ocean pH over the past 3 decades 

      Lauvset, Siv Kari; Gruber, Nicolas; Landschützer, Peter; Olsen, Are; Tjiputra, Jerry (Peer reviewed; Journal article, 2015-03-02)
      We report global long-term trends in surface ocean pH using a new pH data set computed by combining fCO2 observations from the Surface Ocean CO2 Atlas (SOCAT) version 2 with surface alkalinity estimates based on temperature ...
    • Trivial gain of downscaling in future projections of higher trophic levels in the Nordic and Barents Seas 

      Nilsen, Ina; Fransner, Sara Filippa Krusmynta; Olsen, Are; Tjiputra, Jerry; Hordoir, Robinson; Hansen, Cecilie (Journal article; Peer reviewed, 2023)
      Downscaling physical forcing from global climate models is both time consuming and labor demanding and can delay or limit the physical forcing available for regional marine ecosystem modelers. Earlier studies have shown ...
    • A uniform, quality controlled Surface Ocean CO2 Atlas (SOCAT)

J.; Weiss, R.; Wong, C.S.; Yoshikawa-Inoue, H. (Peer reviewed; Journal article, 2013)
      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) project was ...
    • 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 (Peer reviewed; Journal article, 2014-03-07)
      The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity of carbon dioxide) products for the surface oceans. Version 2 ...
