    1. Non-growing-season soil respiration is controlled by freezing and thawing processes in the summer-monsoon-dominated Tibetan alpine grassland

      Yonghui Wang, Huiying Liu, Haegeun Chung, Lingfei Yu, Zhaorong Mi, Yan Geng, Xin Jing, Shiping Wang, Hui Zeng, Guangmin Cao, Xinquan Zhao and Jin-Sheng He

      Accepted manuscript online: 12 SEP 2014 06:28PM EST | DOI: 10.1002/2013GB004760

      Key Points

      • 4-year continuous hourly monitoring of soil CO2 flux (Rs) using automated system
      • Non-growing season cumulative Rs accounted for 11.8-13.2% of the annual total Rs
      • Higher Q10 of thawed than frozen soil can trigger C loss in warmer winter
    2. Climate change reduces the capacity of northern peatlands to absorb the atmospheric carbon dioxide: the different responses of bogs and fens

      Jianghua Wu and Nigel T. Roulet

      Accepted manuscript online: 5 SEP 2014 10:18PM EST | DOI: 10.1002/2014GB004845

      Key Points

      • Models predict fens are more sensitive to climate change than bogs
      • Future climate scenarios reduce bog C sinks and switch fens to sources
      • Thus C sinks in high latitude wetlands are predicted to decrease in future
    3. Global Dry Deposition of Nitrogen Dioxide and Sulfur Dioxide Inferred from Space-Based Measurements

      C. R. Nowlan, R. V. Martin, S. Philip, L. N. Lamsal, N. Krotkov, E. A. Marais, S. Wang and Q. Zhang

      Accepted manuscript online: 3 SEP 2014 04:50PM EST | DOI: 10.1002/2014GB004805

      Key Points

      • NO2 and SO2 dry deposition is derived from space-based measurements.
      • Global and regional budgets of dry deposition are determined.
      • NO2 and SO2 deposition in urban areas is examined.
    4. Iron sources and dissolved-particulate interactions in the seawater of the Western Equatorial Pacific, iron isotope perspectives

      M. Labatut, F. Lacan, C. Pradoux, J. Chmeleff, A. Radic, J.W. Murray, F. Poitrasson, A.M. Johansen and F. Thil

      Accepted manuscript online: 3 SEP 2014 08:36AM EST | DOI: 10.1002/2014GB004928

      Key Points

      • Isotopic composition of dissolved and particulate Fe in seawater
      • Isotopic composition of Fe in marine aerosol, Sepik and margin sediments
      • Non-reductive release would be an important source of dissolved Fe
    5. The impact of Neogene grassland expansion and aridification on the isotopic composition of continental precipitation

      C.P. Chamberlain, M.J. Winnick, H.T. Mix, S.D. Chamberlain and K. Maher

      Accepted manuscript online: 27 AUG 2014 05:34AM EST | DOI: 10.1002/2014GB004822

      Key Points

      • Grassland expansion affected oxygen isotopes of precipitation composition
      • Isotope records record plant ecosystem changes
      • Recycling of water vapor must be taken into account in paleoclimate studies
    6. Close coupling of N-cycling processes expressed in stable isotope data at the redoxcline of the Baltic Sea

      Claudia Frey, Joachim W. Dippner and Maren Voss

      Accepted manuscript online: 23 AUG 2014 08:45AM EST | DOI: 10.1002/2013GB004642

      Key Points

      • d15NNO3 & d18ONO3 through the redoxcline were used to study N processes
      • The apparent isotope effect for denitrification in d15NNO3 was low
      • Denitrification of the water column is closely linked to nitrification
    7. Global patterns of ecosystem carbon flux in forests: A biometric data-based synthesis

      Bing Xu, Yuanhe Yang, Pin Li, Haihua Shen and Jingyun Fang

      Accepted manuscript online: 19 AUG 2014 09:14AM EST | DOI: 10.1002/2013GB004593

      Key Points

      • Synthesis of biometric measurements of carbon flux in forest ecosystems
      • Examination of global patterns of carbon balance in forest ecosystems
      • Comparison of biometric measurements with eddy-covariance observations
