Effects of phytoplankton community on production, size and export of large aggregates: A world-ocean analysis
phytoplankton community production, size export of large aggregates: A world-ocean
2014/4/17
We recorded vertical profiles of size distributions of large particles (.100mm) to a 1000-m depth in the Atlantic, Indian, and Pacific Oceans and in the Mediterranean Sea with theUnderwater Video Prof...

Production dissolution accumulation
2014/4/16
Rates of biogenic silica (bSiO2) production, dissolution, accumulation, and potential bSiO2 export were
determined in a Sargasso Sea mode-water eddy (MWE) during two occupations in April 2007. Standi...

2014/4/16
Incubation experiments with axenic cultures of four common phytoplankton species of the generaChaetoceros,Skeletonema, Prorocentrum, and Micromonaswere performed to test for the production of fluoresc...
Thresholds of gross primary production for the metabolic balance of marine planktonic communities
Thresholds of gross primary production metabolic balance marine planktonic communities
2014/4/18
The notion that less productive marine planktonic communities tend to be heterotrophic was tested by synthesizing reported estimates of the relationships between the net community production or commun...
Enhanced viral production and infection of bacterioplankton during an iron-induced phytoplankton bloom in the Southern Ocean
Enhanced viral production infection of bacterioplankton iron-induced phytoplankton bloom Southern Ocean
2014/4/18
We followed the viral response to Fe-enrichment over 3 weeks during the second iron-enrichment experiment (EisenEx) in the Southern Ocean. Although viral abundance increased in a rather constant way d...

Net community production deep euphotic zone subtropical North Pacific gyre glider surveys
2014/5/16
Seagliders, deployed through most of 2005 in the subtropical North Pacific gyre, made measurements of temperature, salinity, and dissolved oxygen to quantify net community production (NCP) at Station ...
Ammonium regeneration and nitrification rates in the oligotrophic Atlantic Ocean: Implications for new production estimates
Ammonium regeneration nitrification rates the oligotrophic Atlantic Ocean new production estimates
2014/4/21
N regeneration was measured on a transect of the North and South Atlantic, from the United Kingdom to the Falkland Islands, that included extreme oligotrophic conditions. NH4+ and NO{2 oxidation rates...

Dissolved organic matter bacterial production respiration the sea-surface microlayer Atlantic the western Mediterranean Sea
2014/4/21
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
