      Key Points

      • Soil DOC concentration is higher under coniferous forests than under broadleaves
      • N, Fe and Al are important factors for DOC concentration variability in forests
    2. Satellite-detected fluorescence: Decoupling nonphotochemical quenching from iron stress signals in the South Atlantic and Southern Ocean (pages 510–524)

      T. J. Browning, H. A. Bouman and C. M. Moore

      Key Points

      • NPQ experiments were conducted in the South Atlantic and Southern Ocean
      • Significant geographic variability in NPQ characteristics were found
      • NPQ correcting satellite fluorescence revealed correlations with iron stress
    3. Influences of glacier melt and permafrost thaw on the age of dissolved organic carbon in the Yukon River basin (pages 525–537)

      George R. Aiken, Robert G. M. Spencer, Robert G. Striegl, Paul F. Schuster and Peter A. Raymond

      Key Points

      • Oldest DOC found in glacial meltwater and groundwater dominated systems
      • Streams draining peat soils underlain by permafrost enriched in modern carbon
      • Old carbon from thawing permafrost soils not apparent in DOC data at this time
    4. The triple oxygen isotope tracer of primary productivity in a dynamic ocean model (pages 538–552)

      David Nicholson, Rachel H. R. Stanley and Scott C. Doney

      Key Points

      • The triple oxygen isotope tracer system was added to global ocean model
      • Model results evaluated against all available triple oxygen isotope data
      • Biases in steady state equation for production quantified
    5. Natural biogeochemical cycle of mercury in a global three-dimensional ocean tracer model (pages 553–570)

      Key Points

      • The first global 3-D ocean tracer model for mercury is developed
      • Biological pump and water mass age mainly decide mercury distribution
      • Comparison against present-day observations reveals human perturbation
    6. Variability in under-ice export fluxes of biogenic matter in the Arctic Ocean (pages 571–583)

      Catherine Lalande, Eva-Maria Nöthig, Raquel Somavilla, Eduard Bauerfeind, Vladimir Shevchenko and Yuri Okolodkov

      Key Points

      • High under-ice export fluxes were observed on the northern Laptev Sea shelf
      • Low under-ice export fluxes were observed above the central basin
      • Nutrient supply is limiting export fluxes during summer above the central basin
