Integration of MODIS land and atmosphere products with a coupled-process model to estimate gross primary productivity and evapotranspiration from 1 km to global scales
Global Biogeochemical Cycles - Tập 25 Số 4 - Trang n/a-n/a - 2011
Youngryel Ryu, Dennis Baldocchi, Hideki Kobayashi, Catharine van Ingen, Jie Li, T. A. Black, Jason Beringer, Eva van Gorsel, Alexander Knohl, B. E. Law, Olivier Roupsard
A global ocean carbon climatology: Results from Global Data Analysis Project (GLODAP)
Global Biogeochemical Cycles - Tập 18 Số 4 - 2004
Robert M. Key, Alex Kozyr, C. Sabine, Kitack Lee, Rik Wanninkhof, John L. Bullister, Richard A. Feely, Frank J. Millero, Calvin W. Mordy, Tianji Peng
During the 1990s, ocean sampling expeditions were carried out as part of the World Ocean Circulation Experiment (WOCE), the Joint Global Ocean Flux Study (JGOFS), and the Ocean Atmosphere Carbon Exchange Study (OACES). Subsequently, a group of U.S. scientists synthesized the data into easily usable and readily available products. This collaboration is known as the Global Ocean Data Analysi...... hiện toàn bộ
The contribution of ocean‐leaving DMS to the global atmospheric burdens of DMS, MSA, SO2, and NSS SO4=
Global Biogeochemical Cycles - Tập 17 Số 2 - 2003
Mtinkheni Gondwe, Maarten Krol, W. W. C. Gieskes, Wim Klaassen, Hein de Baar
The contribution of ocean‐derived DMS to the atmospheric burdens of a variety of sulphur compounds (DMS, MSA, SO2, and nss SO4=) is quantified from season to season. Such quantification, especially for nss SO4= (the climate‐relevant product of DMS oxidation), is essential for the quanti...... hiện toàn bộ
Amazonian biomass burning‐derived acid and nutrient deposition in the north Andean montane forest of Ecuador
Global Biogeochemical Cycles - Tập 22 Số 4 - 2008
Jens Boy, Rütger Rollenbeck, Carlos Valarezo, Wolfgang Wilcke
We explored the influence of biomass burning in Amazonia and northeastern Latin America on N, C, P, S, K, Ca, Mg, Al, Mn, and Zn cycles of an Andean montane forest in south Ecuador exposed to the Amazon basin between May 1998 and April 2003. We assessed the response of the element budget of three microcatchments (8–13 ha) to the variations in atmospheric deposition between the intensive bu...... hiện toàn bộ
On the origin and timing of rapid changes in atmospheric methane during the Last Glacial Period
Global Biogeochemical Cycles - Tập 14 Số 2 - Trang 559-572 - 2000
Edward J. Brook, Susan Harder, J. P. Severinghaus, Eric J. Steig, Cara M. Sucher
We present high resolution records of atmospheric methane from the GISP2 (Greenland Ice Sheet Project 2) ice core for four rapid climate transitions that occurred during the past 50 ka: the end of the Younger Dryas at 11.8 ka, the beginning of the Bølling‐Allerød period at 14.8 ka, the beginning of interstadial 8 at 38.2 ka, and the beginning of interstadial 12 at 45.5 ka. During these eve...... hiện toàn bộ
In situ evaluation of air‐sea gas exchange parameterizations using novel conservative and volatile tracers
Global Biogeochemical Cycles - Tập 14 Số 1 - Trang 373-387 - 2000
Philip D. Nightingale, Gill Malin, Cliff S. Law, Andrew Watson, Peter S. Liss, M.I. Liddicoat, Jacqueline Boutin, Robert C. Upstill‐Goddard
Measurements of air‐sea gas exchange rates are reported from two deliberate tracer experiments in the southern North Sea during February 1992 and 1993. A conservative tracer, spores of the bacterium Bacillus globigii var. Niger, was used for the first time in an in situ air‐sea gas exchange experiment. This nonvolatile tracer is used to...... hiện toàn bộ
Preferential remineralization of dissolved organic phosphorus and non‐Redfield DOM dynamics in the global ocean: Impacts on marine productivity, nitrogen fixation, and carbon export
Global Biogeochemical Cycles - Tập 29 Số 3 - Trang 325-340 - 2015
Robert T. Letscher, J. Keith Moore
AbstractSelective removal of nitrogen (N) and phosphorus (P) from the marine dissolved organic matter (DOM) pool has been reported in several regional studies. Because DOM is an important advective/mixing pathway of carbon (C) export from the ocean surface layer and its non‐Redfieldian stoichiometry would affect estimates of marine export production per unit N and ...... hiện toàn bộ
Soil organic carbon storage of paddy soils in China using the 1:1,000,000 soil database and their implications for C sequestration
Global Biogeochemical Cycles - Tập 20 Số 3 - 2006
Qinghua Liu, Xuesong Shi, David C. Weindorf, Dongsheng Yu, Yongcun Zhao, Weixia Sun, H. Wang
Organic carbon storage in agricultural soils plays a key role in the terrestrial ecosystem carbon cycle. Paddy soils support important croplands in many parts of the world, especially in Asia. A thorough understanding of organic carbon storage in Chinese paddy soils would be helpful to both greenhouse gases emission and carbon sequestration studies. This paper examines soil organic carbon ...... hiện toàn bộ
Methane emissions from beaver ponds: Rates, patterns, and transport mechanisms
Global Biogeochemical Cycles - Tập 13 Số 4 - Trang 1079-1090 - 1999
Constanze E. Weyhenmeyer
Net methane fluxes as well as methane fluxes via gas bubbles and via molecular diffusion were measured separately at nine different sampling sites throughout a beaver pond located in the low boreal forest region of central Ontario, Canada. In 1990, the average daily methane emission rate was 37.2 ± 30.4 mg CH4 m−2 d−1, yielding...... hiện toàn bộ
Improved estimates of net carbon emissions from land cover change in the tropics for the 1990s
Global Biogeochemical Cycles - Tập 18 Số 2 - 2004
Frédéric Achard, Hugh Eva, Philippe Mayaux, Hans‐Jürgen Stibig, Alan Belward
Recent figures on net forest cover change rates of the world's tropical forest cover are used for the calculation of carbon fluxes in the global budget. By applying our deforestation findings in the humid tropics, complemented by published deforestation figures in the dry tropics, to refereed data on biomass, we produced new estimates of net carbon emissions. These estimates are supported ...... hiện toàn bộ
