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 ...
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...
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...
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 ...
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...
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...
Evidence for efficient regenerated production and dinitrogen fixation in nitrogen-deficient waters of the South Pacific Ocean:impact on new and export production estimates
efficient regenerated production dinitrogen fixation nitrogen-deficient waters
2010/1/15
One of the major objectives of the BIOSOPE cruise, carried out on the R/V Atalante from October-November 2004 in the South Pacific Ocean, was to establish productivity rates along a zonal section trav...
Distribution of micro-organisms along a transect in the South-East Pacific Ocean (BIOSOPE cruise) using epifluorescence microscopy
micro-organisms transect South-East Pacific Ocean epifluorescence microscopy
2010/1/15
The distribution of selected groups of micro-organisms was analyzed along a South-East Pacific Ocean transect sampled during the BIOSOPE cruise in 2004. The transect could be divided into four regions...
Distribution of inorganic and organic nutrients in the South Pacific Ocean − evidence for long-term accumulation of organic matter in nitrogen-depleted waters
inorganic and organic nutrients South Pacific Ocean − evidence long-term accumulation
2010/1/15
During the BIOSOPE cruise the RV Atalante was dedicated to study the biogeochemical properties in the South Pacific between the Marquesas Islands (141° W–8° S) and the Chilean upwelling (73° W–34° S)....
Picoplankton diversity in the South-East Pacific Ocean from cultures
Picoplankton diversity South-East Pacific Ocean cultures
2010/1/15
In late 2004, the BIOSOPE cruise sailed between the equatorial influenced waters off the Marquesas Islands and the nutrient enriched waters of the Chilean upwelling. Along the way, it explored the Sou...
Phospholipid synthesis rates in the eastern subtropical South Pacific Ocean
Phospholipid synthesis rates eastern subtropical South Pacific Ocean
2010/1/15
Membrane lipid molecules are a major component of planktonic organisms and this is particularly true of the microbial picoplankton that dominate the open ocean; with their high surface-area to volume ...
Phosphate availability and the ultimate control of new nitrogen input by nitrogen fixation in the tropical Pacific Ocean
Phosphate availability ultimate control new nitrogen input nitrogen fixation
2010/1/15
Due to the low atmospheric input of phosphate into the open ocean, it is one of the key nutrients that could ultimately control primary production and carbon export into the deep ocean. The observed t...
The roles of ENSO on the occurrence of abruptly recurving tropical cyclones over the Western North Pacific Ocean Basin
ENSO recurving tropical cyclones the Western North Pacific Ocean Basin
2010/1/25
The abruptly recurving tropical cyclones over the Western North Pacific Ocean Basin during El Niño and La Niña events are studied. Temporal and spatial variations of these anomalous trac...
