Numerical simulations of oceanic oxygen cycling in the FAMOUS Earth-System model: FAMOUS-ES, version 1.0
Numerical simulations oceanic oxygen cycling FAMOUS Earth-System model FAMOUS-ES, version 1.0
2014/12/19
Addition and validation of an oxygen cycle to the ocean component of the FAMOUS climate model are described. At the surface, FAMOUS overestimates northern hemisphere oxygen concentrations whereas, at ...
Optimising the FAMOUS climate model: inclusion of global carbon cycling
Optimising the FAMOUS climate model global carbon cycling
2014/12/17
FAMOUS fills an important role in the hierarchy of climate models, both explicitly resolving atmospheric and oceanic dynamics yet being sufficiently computationally efficient that either very long sim...
Exploring Isotopic Signatures of Lake El'gygytgyn Sediments for Evidence of Anoxia and Methane Cycling over the Past 50,000 Years
Exploring Isotopic Signatures Lake El'gygytgyn Sediments Evidence of Anoxia and Methane Cycling over the Past 50,000 Years
2014/10/21
Compound specific isotope analysis of lake sediments is a powerful tool in deciphering evidence of changing climatic and paleoenvironmental conditions through time. Isotopic analysis of Lake El’gygytg...
The role of polysaccharides and diatom exudates in the redox cycling of Fe and the photoproduction of hydrogen peroxide in coastal seawaters
polysaccharides and diatom exudates the redox cycling of Fe the photoproduction of hydrogen peroxide coastal seawaters
2010/1/21
The effect of artificial acidic polysaccharides (PS) and exudates of Phaeodactylum tricornutum on the half-life of Fe(II) in seawater was investigated in laboratory experiments. Strong photochemical h...
Chemolithoautotrophic production mediating the cycling of the greenhouse gases N2O and CH4 in an upwelling ecosystem
Chemolithoautotrophic production the greenhouse gases N2O and CH4 an upwelling ecosystem
2010/1/21
The high availability of electron donors occurring in coastal upwelling ecosystems with marked oxyclines favours chemoautotrophy, in turn leading to high N2O and CH4 cycling associated with aerobic NH...
Distribution,origin and cycling of carbon in the Tana River (Kenya):a dry season basin-scale survey from headwaters to the delta
Distribution origin cycling carbon season basin-scale survey headwaters delta
2010/1/21
The Tana River basin (TRB) is the largest in Kenya (~120 000 km2). We conducted a survey during the dry season throughout the TRB, analyzing a broad suite of biogeochemical parameters. Biogeochemical ...
Marine geochemical data assimilation in an efficient Earth System Model of global biogeochemical cycling
Marine geochemical data assimilation Earth System Model global biogeochemical cycling
2010/1/14
We have extended the 3-D ocean based "Grid ENabled Integrated Earth system model" (GENIE-1) to help understand the role of ocean biogeochemistry and marine sediments in the long-term (~100 to 100 000 ...
Nitrous oxide fluxes and nitrogen cycling along a pasture chronosequence in Central Amazonia,Brazil
Nitrous oxide fluxes nitrogen cycling pasture chronosequence Central Amazonia
2010/1/12
We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pastur...
Seasonal cycling of phosphorus in the Southern Bight of the North Sea
Seasonal cycling phosphorus Southern Bight North Sea
2010/1/12
We have investigated the seasonal cycle of nutrients, chlorophyll a, dissolved organic nitrogen (DON), and dissolved and particulate organic carbon (DOC and POC) for 10 stations in the Belgian coastal...
Past and present of sediment and carbon biogeochemical cycling models
Past present sediment carbon biogeochemical cycling models
2010/1/7
The global carbon cycle is part of the much more extensive sedimentary cycle that involves large masses of carbon in the Earth's inner and outer spheres. Studies of the carbon cycle generally followed...
