Oxygen penetration deep into the sediment of the South Pacific gyre
Oxygen penetration sediment South Pacific gyre
2010/1/20
Sediment oxygen concentration profiles and benthic microbial oxygen consumption rates were investigated during an IODP site survey in the South Pacific Gyre. Primary production, particle fluxes and se...
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...
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...
Gross community production and metabolic balance in the South Pacific Gyre,using a non intrusive bio-optical method
Gross community production metabolic balance South Pacific Gyre bio-optical method
2010/1/15
The very clear waters of the South Pacific Gyre likely constitute an end-member of oligotrophic conditions which remain essentially unknown with respect to its impact on carbon fixation and exportatio...
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 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)....
Volume distribution for particles between 3.5 to 2000 μm in the upper 200 m region of the South Pacific Gyre
Volume distribution particles 3.5 to 2000 μm South Pacific Gyre
2010/1/15
The French JGOFS BIOSOPE cruise crossed the South Pacific Gyre (SPG) on a transect between the Marquesas Islands and the Chilean coast on a 7500 km transect (8° S–34° S and 8° W–72° W). The number and...
Relationships between the surface concentration of particulate organic carbon and optical properties in the eastern South Pacific and eastern Atlantic Oceans
surface concentration particulate organic carbon optical properties eastern South Pacific
2010/1/15
We have examined several approaches for estimating the surface concentration of particulate organic carbon, POC, from optical measurements of spectral remote-sensing reflectance, Rrs(λ), using field d...
Heterotrophic bacterial production in the eastern South Pacific:longitudinal trends and coupling with primary production
Heterotrophic bacterial production eastern South Pacific longitudinal trends primary production
2010/1/15
Spatial variation of heterotrophic bacterial production and phytoplankton primary production were investigated across the eastern South Pacific Ocean (−141° W, −8° S to −72° W, ͨ...
