Quantifying the carbon uptake by vegetation for Europe on a 1 km2 resolution using a remote sensing driven vegetation model
Quantifying the carbon uptake Europe on a 1 km2 resolution remote sensing driven vegetation model
2014/12/12
In this study we compare monthly gross primary productivity (GPP) time series (2000–2007), computed for Europe with the Biosphere Energy Transfer Hydrology (BETHY/DLR) model with monthly data from the...
Improved sapflow methodology reveals considerable night-time ozone uptake by Mediterranean species
sapflow methodology considerable night-time ozone Mediterranean species
2010/1/21
Due to the evident tropospheric ozone impact on plant productivity, an accurate ozone risk assessment for the vegetation has become an issue. There is a growing evidence that ozone stomatal uptake may...
Physiological controls on seawater uptake and calcification in the benthic foraminifer Ammonia tepida
Physiological controls seawater uptake calcification benthic foraminifer Ammonia tepida
2010/1/21
To analyze the relation between seawater uptake and calcification, we incubated juveniles of the benthic foraminifer Ammonia tepida with various fluorescent probes and visualised them afterwards with ...
Nitrogen uptake and regeneration pathways in the equatorial Pacific:a basin scale modeling study
Nitrogen uptake regeneration pathways equatorial Pacific basin scale modeling
2010/1/21
It is well known that most primary production is fueled by regenerated nitrogen in the open ocean. Therefore, studying the nitrogen cycle by focusing on uptake and regeneration pathways would advance ...
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the ...
Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake
atmospheric and terrestrial CO2 feedbacks fertilization-induced marine carbon uptake
2010/1/20
The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated by studi...
The role of ocean transport in the uptake of anthropogenic CO2
role ocean transport uptake anthropogenic CO2
2010/1/19
We compare modeled oceanic carbon uptake in response to pulse CO2 emissions using a suite of global ocean models and Earth system models. In response to a CO2 pulse emission of 590 Pg C (corresponding...
Marine ecosystem community carbon and nutrient uptake stoichiometry under varying ocean acidification during the PeECE III experiment
Marine ecosystem community carbon nutrient uptake stoichiometry ocean acidification
2010/1/18
Changes to seawater inorganic carbon and nutrient concentrations in response to the deliberate CO2 perturbation of natural plankton assemblages were studied during the 2005 Pelagic Ecosystem CO2 Enric...
Growth and specific P-uptake rates of bacterial and phytoplanktonic communities in the Southeast Pacific (BIOSOPE cruise)
specific P-uptake rates bacterial and phytoplanktonic communities Southeast Pacific
2010/1/14
Predicting heterotrophic bacteria and phytoplankton specific growth rates (μ ) is of great scientific interest. Many methods have been developed in order to assess bacterial or phytoplankton μ. One wi...
Assessing the ability of three land ecosystem models to simulate gross carbon uptake of forests from boreal to Mediterranean climate in Europe
three land ecosystem models gross carbon uptake forests Mediterranean climate
2010/1/14
Three terrestrial biosphere models (LPJ, Orchidee, Biome-BGC) were evaluated with respect to their ability to simulate large-scale climate related trends in gross primary production (GPP) across Europ...
Assessing the potential long-term increase of oceanic fossil fuel CO2 uptake due to CO2-calcification feedback
potential long-term increase oceanic fossil fuel CO2-calcification feedback
2010/1/14
Plankton manipulation experiments exhibit a wide range of sensitivities of biogenic calcification to simulated anthropogenic acidification of the ocean, with the "lab rat" of planktic calcifiers, Emil...
Diatoms and their influence on the biologically mediated uptake of atmospheric CO2 in the Arabian Sea upwelling system
Diatoms biologically mediated uptake atmospheric CO2 Sea upwelling system
2010/1/13
Sediment trap experiments have been carried out in order to study processes controlling shifts from diatom to non-diatom dominated systems in the western Arabian Sea. One of our major problems was to ...
Global uptake of carbonyl sulfide (COS) by terrestrial vegetation:Estimates corrected by deposition velocities normalized to the uptake of carbon dioxide (CO2)
Global uptake carbonyl sulfide terrestrial vegetation deposition velocities
2010/1/12
COS uptake by trees, as observed under dark/light changes and under application of the plant hormone abscisic acid, exhibited a strong correlation with the CO2 assimilation rate and the stomatal condu...
