Modeling the Carbon Cycle of a Subtropical Chinese Fir Plantation Using a Multi-Source Data Fusion Approach
process-based terrestrial ecosystem model model–data fusion multi-source data carbon cycle plantation
2024/2/5
Process-based terrestrial ecosystem models are increasingly being used to predict carbon (C) cycling in forest ecosystems. Given the complexity of ecosystems, these models inevitably have certain defi...
Radiocarbon in Corals: Records of the Carbon Cycle, Surface Circulation and Climate
Carbon Cycle Surface Circulation
2015/7/31
For more than two decades, coral skeletons have been used to reconstruct records of isotopic and chemical ratios in surface seawater (for reviews, see Druffel, 1997a; Gagan et al., 2000). Here I demon...
Understanding the Role of the Biological Pump in the Global Carbon Cycle:An Imperative for Ocean Science
Biological Pump Global Carbon Cycle Ocean Science
2015/7/20
Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in ...
Ocean Dynamics and the Carbon Cycle:Principles and Mechanisms
Ocean Dynamics Carbon Cycle Principles and Mechanisms
2015/7/15
Williams and Follows combined their expertise to write a book targeted at honors undergraduate or graduate students, as well as at professionals in ocean science who need to learn the fundamentals of ...
Various human activities, including
fossil fuel combustion and forest clearing, emit
about eight petagrams (or billion tons) of carbon
in the form of CO2 into the atmosphere annually.

Chemical Oceanography and the Marine Carbon Cycle reflects the two authors' wealth of research and teaching experience, and the community is fortunate that Steve Emerson was able to complete this majo...
Record of Early Toarcian carbon cycle perturbations in a nearshore environment: the Bascharage section (easternmost Paris Basin)
Black shale deposit early Jurassic the negative carbon isotope
2015/1/6
In order to understand the significance of the worldwide deposition of black shale facies in the Early Toarcian (~ 183 Ma), considerable attention has been drawn to this Early Jurassic sub-stage over ...
Limiting the parameter space in the Carbon Cycle Data Assimilation System (CCDAS)
Limiting the parameter space Carbon Cycle Data Assimilation System
2014/12/19
Terrestrial ecosystem models are employed to calculate the sources and sinks of carbon dioxide between land and atmosphere. These models may be heavily parameterised. Where reliable estimates are unav...
