Short-term response of the coccolithophore Emiliania huxleyi to an abrupt change in seawater carbon dioxide concentrations
Short-term response the coccolithophore Emiliania huxleyi an abrupt change in seawater carbon dioxide concentrations
2010/1/21
The response of the coccolithophore Emiliania huxleyi to rising CO2 concentrations is well documented for acclimated cultures where cells are exposed to the CO2 treatments for several generations prio...
Gas storage plays an essential role in both carbon sequestration and hydrogen-fuelled cars, two of the most touted green technologies. To date, however, most proposed methods for storing gases in thes...
Chronic nitrogen addition causes a reduction in soil carbon dioxide efflux during the high stem-growth period in a tropical montane forest but no response from a tropical lowland forest on a decadal time scale
Chronic nitrogen addition soil carbon dioxide efflux the high stem-growth period a tropical montane forest a tropical lowland forest
2010/1/21
Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We studied the response of soil carbon dioxide (CO2) efflux to long-term experimental N addition (125 kg N ha−1 yr&...

The current paper reviews the experimental setup of the CarboEurope Experimental Strategy (CERES) campaigns with the aim of providing an overview of the instrumentation used, the data-set and associat...
An argument for the use of two-layer SVAT schemes to simulate terrestrial carbon dioxide fluxes
surface temperatures soil respiration carbon dioxide fluxes
2009/6/5
An order-of-magnitude argument shows that the different surface temperatures of soil and sparse vegetation affect carbon assimilation and soil respiration significantly. However, regulation of assimi...
The Thetford Project (1968–1976) was a keystone project for the newly established Institute of Hydrology. Its primary objective was to elucidate the processes underlying evaporation of transpired wate...
