Global high-resolution simulations of CO2 and CH4 using a NIES transport model to produce a priori concentrations for use in satellite data retrievals
Global high-resolution simulations CO2 and CH4 NIES transport model produce a priori concentrations satellite data retrievals
2014/12/17
The Greenhouse gases Observing SATellite (GOSAT) measures column-averaged dry air mole fractions of carbon dioxide and methane (XCO2 and XCH4, respectively). Since the launch of GOSAT, model-simulated...
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...
Intercomparison of measurements of NO2 concentrations in the atmosphere simulation chamber SAPHIR during the NO3Comp campaign
NO2 concentrations atmosphere simulation chamber SAPHIR NO3Comp campaign
2010/2/8
NO2 concentrations were measured by various instruments during the NO3Comp campaign at the atmosphere simulation chamber SAPHIR at Forschungszentrum Jülich, Germany, in June 2007. Analytical methods i...
Polycyclic aromatic hydrocarbons (PAHs) in Norwegian and Russian Arctic marine sediments:concentrations,geographical distribution and sources
Polycyclic aromatic hydrocarbons Norwegian Russian Arctic marine sediments
2009/12/3
Polycyclic aromatic hydrocarbons (PAHs) are key contaminants of concern under the Arctic Environmental Monitoring Programme (AMAP) due to their carcinogenic potential. The concentration of the differe...
Testing the relationship between the solar radiation dose and surface DMS concentrations using in situ data
solar radiation dose surface DMS concentrations situ data
2010/1/21
The proposed strong positive relationship between dimethylsulphide (DMS) concentration and the solar radiation dose (SRD) received into the surface ocean is tested using data from the Atlantic Meridio...
Influence of elevated CO2 concentrations on cell division and nitrogen fixation rates in the bloom-forming cyanobacterium Nodularia spumigena
elevated CO2 concentrations cell division nitrogen fixation rates bloom-forming cyanobacterium
2010/1/21
The surface ocean absorbs large quantities of the CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in seawater, it reacts to form carbonic acid. While this phenomenon, called...
Concentrations and fluxes of biogenic volatile organic compounds above a Mediterranean macchia ecosystem in western Italy
Concentrations fluxes biogenic volatile organic compounds macchia ecosystem
2010/1/20
Emission rates and concentrations of biogenic volatile organic compounds (BVOCs) were measured at a Mediterranean coastal site at Castelporziano, approximately 25 km south-west of Rome, between 7 May ...
Methodology and calibration for continuous measurements of biogeochemical trace gas and O2 concentrations from a 300-m tall tower in central Siberia
Methodology calibration continuous measurements biogeochemical trace gas O2 concentrations
2010/2/8
We present an integrated system for measuring atmospheric concentrations of CO2, O2, CH4, CO, and N2O in central Siberia. Our project aims to demonstrate the feasibility of establishing long-term, con...
Primary production during nutrient-induced blooms at elevated CO2 concentrations
Primary production nutrient-induced blooms elevated CO2 concentrations
2010/1/20
A CO2 enrichment experiment (PeECE III) was carried out in 9 mesocosms in which the seawater carbonate system was manipulated to achieve three different levels of pCO2. At the onset of the experimenta...

The potential impact of seawater acidification on the concentrations of dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSP), and the activity of the enzyme DMSP-lyase was investigated during a...
Minor changes in soil organic carbon and charcoal concentrations detected in a temperate deciduous forest a year after an experimental slash-and-burn
Minor changes soil organic carbon charcoal concentrations temperate deciduous forest
2010/1/14
Anthropogenic fires affected the temperate deciduous forests of Central Europe over millennia. Biomass burning releases carbon to the atmosphere and produces charcoal, which potentially contributes to...
