A new study from CU Boulder finds that hundreds of millions of years ago, small single-celled organisms may have evolved into larger multicellular life forms to better propel themselves through icy wa...
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...
A rapid transition from ice covered CO2–rich waters to a biologically mediated CO2 sink in the eastern Weddell Gyre
rapid transition ice covered CO2–rich waters CO2 sink
2010/1/18
Circumpolar Deep Water (CDW), locally called Warm Deep Water (WDW), enters the Weddell Gyre in the southeast, roughly at 25° E to 30° E. In December 2002 and January 2003 we studied the effect of entr...
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

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)....
Optical backscattering properties of the clearest natural waters
Optical backscattering properties clearest natural waters
2010/1/15
During the BIOSOPE field campaign October–December 2004, measurements of inherent optical properties from the surface to 500 m depth were made with a ship profiler at stations covering over 8000 km th...
Natural variability of bio-optical properties in Case 1 waters:attenuation and reflectance within the visible and near-UV spectral domains,as observed in South Pacific and Mediterranean waters
Natural variability bio-optical properties attenuation reflectance
2010/1/14
The optical properties of Case 1 waters have been empirically related to the chlorophyll concentration, [Chl], historically used as an index of the trophic state and of the abundance of the biological...
Detailed validation of the bidirectional effect in various Case 1 waters for application to ocean color imagery
Detailed validation bidirectional effect ocean color imagery
2010/1/14
The radiance viewed from the ocean depends on the illumination and viewing geometry along with the water properties, and this variation is called the bidirectional effect. This bidirectional effect de...
Carbon dynamics and CO2 air-sea exchanges in the eutrophied coastal waters of the Southern Bight of the North Sea:a modelling study
Carbon dynamics CO2 air-sea exchanges eutrophied coastal waters modelling study
2010/1/7
A description of the carbonate system has been incorporated in the MIRO biogeochemical model to investigate the contribution of diatom and Phaeocystis blooms to the seasonal dynamics of air-sea CO2 ex...
