Estimating uncertainty in ecosystem budget calculations
Ecosystem nutrient budgets often report values for pools and fluxes without any indication of uncertainty, which makes it difficult to evaluate the significance of findings or make comparisons across systems. We present ...
Effects of tropospheric ozone pollution on net primary productivity and carbon storage in terrestrial ecosystems of China
(American Geophysical Union, 2007-11-17)
We investigated the potential effects of elevated ozone (O3) along with climate variability, increasing CO2, and land use change on net primary productivity (NPP) and carbon storage in China's terrestrial ecosystems for ...
Linkages among runoff, dissolved organic carbon, and the stable oxygen isotope composition of seawater and other water mass indicators in the Arctic Ocean
(American Geophysical Union, 2005-12-07)
Concentrations of dissolved organic carbon (DOC) and δ18O values have been determined following sampling of runoff from a number of major arctic rivers, including the Ob, Yenisey, Lena, Kolyma, Mackenzie and Yukon in ...

Corrigendum: Sokolov, A., and Coauthors, 2009: Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters. J. Climate, 22, 5175–5204.
Pattern and variation of C:N:P ratios in China’s soils : a synthesis of observational data
Inspired by previous studies that have indicated consistent or even well-constrained relationships among carbon (C), nitrogen (N) and phosphorus (P) in soils, we have endeavored to explore general soil C:N:P ratios in ...
Consequences of considering carbon–nitrogen interactions on the feedbacks between climate and the terrestrial carbon cycle
(American Meteorological Society, 2008-08-01)
The impact of carbon–nitrogen dynamics in terrestrial ecosystems on the interaction between the carbon cycle and climate is studied using an earth system model of intermediate complexity, the MIT Integrated Global Systems ...
International Carbon Coordination : Roger Revelle’s legacy in the Intergovernmental Oceanographic Commission
(Oceanography Society, 2010-09)
Since its inception in 1960, the Intergovernmental Oceanographic Commission (IOC) has been responsible for organizing and coordinating the scientific investigation of ocean carbon. Roger Revelle (Scripps Institution of ...
Global economic effects of changes in crops, pasture, and forests due to changing climate, carbon dioxide, and ozone
Multiple environmental changes will have consequences for global vegetation. To the extent that crop yields and pasture and forest productivity are affected there can be important economic consequences. We examine the ...
Probabilistic forecast for twenty-first-century climate based on uncertainties in emissions (without policy) and climate parameters
(American Meteorological Society, 2009-10-01)
The Massachusetts Institute of Technology (MIT) Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model’s first projections were published in 2003, ...
Soil respiration at mean annual temperature predicts annual total across vegetation types and biomes
(Copernicus Publications on behalf of the European Geosciences Union, 2010-07-09)
Soil respiration (SR) constitutes the largest flux of CO2 from terrestrial ecosystems to the atmosphere. However, there still exist considerable uncertainties as to its actual magnitude, as well as its spatial and interannual ...
