  • Interannual variability in the wintertime air–sea flux of carbon dioxide in the northern North Atlantic, 1981–2001 

    Olsen, Are; Bellerby, Richard G. J.; Johannessen, Truls; Omar, Abdirahman M.; Skjelvan, Ingunn (Elsevier, 2003)
    Gridded fields of sea surface temperature (SST), sea level pressure (SLP), and wind speed were used in combination with data for the atmospheric mole fraction of CO2 and an empirical relationship between measured values ...

  • Mg/Ca ratios in the planktonic foraminifer Neogloboquadrina pachyderma (sinistral) in the northern North Atlantic/Nordic Seas 

    Meland, Marius Yddal; Jansen, Eystein; Elderfield, Henry; Dokken, Trond Martin; Olsen, Are; Bellerby, Richard G. J. (American Geophysical Union, 2006-06-15)
    In core top samples in the Nordic Seas, Mg/Ca ratios of N. pachyderma (sin.) are generally consistent with previous high-latitude calibration data but do not reflect the modern calcification temperature gradient from 2ºC ...

  • Ocean abyssal carbon experiments at 0.7 and 4 km depth 

    Haugan, Peter Mosby; Brewer, Peter G.; Peltzer, Edward T.; Walz, Peter; Aya, Izuo; Yamane, Kenji; Kojima, Ryuji; Nakajima, Yasuharu; Nakayama, Noriko; Hove, Joakim; Johannessen, Truls; Bellerby, Richard G. J.; Alendal, Guttorm (Elsevier, 2005)
    Observations from small-scale (20 to 90 litres) CO2 experiments conducted off the coast of California at 684 m depth and at 3942 m depth are discussed. In both experiments, when the seawater velocity was sufficiently strong, ...

  • Seasonal variation in marine C:N:P stoichiometry: can the composition of seston explain stable Redfield ratios? 

    Frigstad, Helene; Andersen, T.; Hessen, D. O.; Naustvoll, L. J.; Johnsen, Torbjørn Martin; Bellerby, Richard G. J. (Copernicus Publications on behalf of the European Geosciences Union, 2011)
    Seston is suspended particulate organic matter, comprising a mixture of autotrophic, heterotrophic and detrital material. Despite variable proportions of these components, marine seston often exhibits relatively small ...
