The role of phytoplankton dynamics in the seasonal and interannual variability of carbon in the subpolar North Atlantic – a modeling study
phytoplankton dynamics seasonal interannual variability carbon subpolar North Atlantic modeling study
2014/12/10
We developed an ecosystem/biogeochemical model system, which includes multiple phytoplankton functional groups and carbon cycle dynamics, and applied it to investigate physical-biological interactions...
Synergistic effects of iron and temperature on Antarctic phytoplankton and microzooplankton assemblages
Synergistic effects iron and temperature Antarctic phytoplankton microzooplankton assemblages
2010/1/21
Iron availability and temperature are important limiting factors for the biota in many areas of the world ocean, and both have been predicted to change in future climate scenarios. However, the impact...
Spatial distribution of the iron supply to phytoplankton in the Southern Ocean: a model study
Spatial distribution the iron supply phytoplankton the Southern Ocean a model study
2010/1/21
An upgraded version of the biogeochemical model SWAMCO is coupled to the ocean-sea-ice model NEMO-LIM to explore processes governing the spatial distribution of the iron supply to phytoplankton in the...
Bioavailability of organically bound Fe to model phytoplankton of the Southern Ocean
Bioavailability organically bound Fe phytoplankton Southern Ocean
2010/1/21
Iron (Fe) is known to be mostly bound to organic ligands and to limit primary productivity in the Southern Ocean. It is thus important to investigate the bioavailability of organically bound Fe. In th...
Distribution of calcifying and silicifying phytoplankton in relation to environmental and biogeochemical parameters during the late stages of the 2005 North East Atlantic Spring Bloom
calcifying and silicifying phytoplankton environmental and biogeochemical parameters Atlantic Spring Bloom
2010/1/21
The late stage of the North East Atlantic (NEA) spring bloom was investigated during June 2005 along a transect section from 45 to 66° N between 15 and 20° W in order to characterize the contribution ...
Effects of the pH/pCO2 control method on medium chemistry and phytoplankton growth
Effects pH/pCO2 control method medium chemistry phytoplankton growth
2010/1/20
The control of key chemical parameters in phytoplankton cultures, such as pCO2, pH and Ω (the saturation state of calcium carbonate), is made difficult by the interdependence of these parameters and b...
Satellite-detected fluorescence reveals global physiology of ocean phytoplankton
Satellite-detected fluorescence global physiology ocean phytoplankton
2010/1/20
Phytoplankton photosynthesis links global ocean biology and climate-driven fluctuations in the physical environment. These interactions are largely expressed through changes in phytoplankton physiolog...
Sub meso scale phytoplankton distribution in the North East Atlantic surface waters determined with an automated flow cytometer
Sub meso scale phytoplankton distribution Atlantic surface waters flow cytometer
2010/1/19
Phytoplankton cells in the size range ~1–50 μm were analysed in surface waters using an automated flow cytometer, the Cytosub (http://www.cytobuoy.com), from the Azores to the French Brittany during s...
Regulation of phytoplankton carbon to chlorophyll ratio by light,nutrients and temperature in the Equatorial Pacific Ocean:a basin-scale model
phytoplankton carbon chlorophyll ratio Equatorial Pacific Ocean basin-scale model
2010/1/19
The complex effects of light, nutrients and temperature lead to a variable carbon to chlorophyll (C:Chl) ratio in phytoplankton cells. Using field data collected in the Equatorial Pacific, we derived ...
Microzooplankton grazing and phytoplankton growth in marine mesocosms with increased CO2 levels
Microzooplankton grazing phytoplankton growth marine mesocosms CO2 levels
2010/1/18
Microzooplankton grazing and algae growth responses to increasing pCO2 levels (350, 700 and 1050 μatm) were investigated in nitrate and phosphate fertilized mesocosms during the PeECE III experiment 2...
Coupling of heterotrophic bacteria to phytoplankton bloom development at different pCO2 levels:a mesocosm study
heterotrophic bacteria phytoplankton bloom development pCO2 levels
2010/1/18
The predicted rise in anthropogenic CO2 emissions will increase CO2 concentrations and decrease seawater pH in the upper ocean. Recent studies have revealed effects of pCO2 induced changes in seawater...
Climate-mediated changes to mixed-layer properties in the Southern Ocean:assessing the phytoplankton response
Climate-mediated changes mixed-layer properties Southern Ocean phytoplankton response
2010/1/15
Concurrent changes in ocean chemical and physical properties influence phytoplankton dynamics via alterations in carbonate chemistry, nutrient and trace metal inventories and upper ocean light environ...
Effects of increased atmospheric CO2 on small and intermediate sized osmotrophs during a nutrient induced phytoplankton bloom
