Anthropogenic carbon distribution in the eastern South Pacific Ocean
Anthropogenic carbon distribution eastern South Pacific Ocean
2010/1/19
We present results of the CO2/carbonate system from the BIOSOPE cruise in the Eastern South Pacific Ocean, in an area not sampled previously. In particular, we present estimates of the anthropogenic c...
Sinking rates and ballast composition of particles in the Atlantic Ocean:implications for the organic carbon fluxes to the deep ocean
Sinking rates ballast composition Atlantic Ocean organic carbon fluxes deep ocean
2010/1/19
The flux of materials to the deep sea is dominated by larger, organic-rich particles with sinking rates varying between a few meters and several hundred meters per day. Mineral ballast may regulate th...
Evidence for a multi-species coccolith volume change over the past two centuries:understanding a potential ocean acidification response
multi-species coccolith volume change potential ocean acidification response
2010/1/18
Major questions surround the species-specific nature of coccolithophore calcification in response to rising atmospheric CO2 levels. Here we present CaCO3 particle volume distribution data from the coc...
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...
First description of the Minnesota Earth System Model for Ocean biogeochemistry (MESMO 1.0)
First description Minnesota Earth System Model Ocean biogeochemistry
2010/2/5
Here we describe the first version of the Minnesota Earth System Model for Ocean biogeochemistry (MESMO 1.0), an intermediate complexity model based on the Grid ENabled Integrated Earth system model (...
Calcite production by coccolithophores in the south east Pacific Ocean
Calcite production coccolithophores south east Pacific Ocean
2010/1/18
BIOSOPE cruise covered an oceanographic transect through the centre of the South Pacific Gyre (SPG) from the Marquesas archipelago to the Peru-Chile upwelling (PCU). Water samples from 6 depths in the...

Does ocean acidification induce an upward flux of marine aggregates?
ocean acidification upward flux marine aggregates
2010/1/18
The absorption of anthropogenic atmospheric carbon dioxide (CO2) by the ocean provokes its acidification. This acidification may alter several oceanic processes, including the export of biogenic carbo...
Factors limiting heterotrophic bacterial production in the southern Pacific Ocean
Factors heterotrophic bacterial production southern Pacific Ocean
2010/1/15
The role of potential factors limiting bacterial growth was investigated along vertical and longitudinal gradients across the South Eastern Pacific Gyre. The effects of glucose, nitrate, ammonium and ...
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...
Biochemical characteristics and bacterial community structure of the sea surface microlayer in the South Pacific Ocean
Biochemical characteristics bacterial community structure sea surface microlayer
2010/1/15
The chemical and biological characteristics of the surface microlayer were determined during a transect across the South Pacific Ocean in October-December 2004. Concentrations of particulate organic c...
Numerical study of the response of the ocean to a northerly wind jet in the equatorial Eastern Pacific
Numerical study ocean northerly wind jet equatorial Eastern Pacific
2010/1/27
The response of the equatorial and South American coastal ocean circulation to the anomalous March 2002 wind jet extending from the Gulf of Panama to 6° S is studied in a linear ocean model. Two exper...
Particle optical backscattering along a chlorophyll gradient in the upper layer of the eastern South Pacific Ocean
Particle optical backscattering chlorophyll gradient upper layer Pacific Ocean
2010/1/15
The particulate scattering, bp, and backscattering, bbp, coefficients are determined by the concentration and physical properties of suspended particles in the ocean. They provide a simple description...
The impact on atmospheric CO2 of iron fertilization induced changes in the ocean's biological pump
