Study Shows North Atlantic Ocean CO2 Storage Doubled Over Last Decade
carbon dioxide ocean life fossil fuels
2016/2/23
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows that the North Atlantic absorbed 100 percent more man-made carbon dioxide over the last decade, compared ...
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...

Nitrogen fixation along a north-south transect in the eastern Atlantic Ocean
Nitrogen fixation north-south transect eastern Atlantic Ocean
2014/4/22
Nitrogenase activity, indicative of N2 fixation, was measured in the surface waters along a north-south transect in the eastern Atlantic Ocean, from Texel (The Netherlands, 53°N) to Cape Town (South A...
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
Large-scale variability in surface bacterial carbon demand and growth efficiency in the subtropical northeast Atlantic Ocean
2014/4/23
We present surface estimates of bacterial respiration, bacterial heterotrophic production (BHP), and bacterial growth efficiency (BGE), and their relationship with nutrient availability, along a troph...
Influence of the Amazon River plume on distributions of free-living and symbiotic cyanobacteria in the western tropical north Atlantic Ocean
Influence of the Amazon River plume distributions of free-living symbiotic cyanobacteria the western tropical north Atlantic Ocean
2014/4/23
The vertical and horizontal distributions of seven diazotrophic populations in the western tropical north Atlantic (WTNA) Ocean were examined using a nifH DNA quantitative polymerase chain reaction (Q...
Variation in the transfer of energy in marine plankton along a productivity gradient in the Atlantic Ocean
the transfer of energy marine plankton productivity gradient Atlantic Ocean
2014/5/5
Plankton play a key role in oceanic carbon flux as the primary biological mechanism for the sequestration of carbon out of the atmosphere into surface waters. The transfer of energy between phytoplank...
Effects of dust deposition and river discharges on trace metal composition of Trichodesmium spp. in the tropical and subtropical North Atlantic Ocean
dust deposition river discharges trace metal composition Trichodesmium spp. tropical subtropical North Atlantic Ocean
2014/5/4
We present the elemental composition (Al, Cd, Co, Cu, Fe, Mn, Mo, Ni, V, Zn, and P) of field-collected Trichodesmium populations. To distinguish the effects of river discharges (Amazon and Niger River...
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
2014/5/19
Because of recent findings that Fe is a limiting factor for phytoplankton activity even at relatively high dissolved iron (DFe) concentrations, the potential importance of Fe limitation was revisited ...
Bioavailability of iron to Trichodesmium colonies in the western subtropical Atlantic Ocean
iron Trichodesmium colonies western subtropical Atlantic Ocean
2014/5/22
Trichodesmium provides new nitrogen (N) to marine surface waters via N2 fixation, a process that requires a substantial amount of iron (Fe). Organic ligands in seawater that bind Fe could either incre...
