Responses to iron limitation in two colonies of Stylophora pistillata exposed to high temperature: Implications for coral bleaching
Stylophora pistillata Responses coral bleaching
2014/4/8
Exposing the coral Stylophora pistillata to seawater depleted in available iron by complexation with the strong
chelator desferrioxamine B reduces the photosynthetic efficiency and alters the pigment...
Variations in Synechococcus cell quotas of phosphorus, sulfur, manganese, iron, nickel, and zinc within mesoscale eddies in the Sargasso Sea
phosphorus sulfur manganese iron
2014/4/16
The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep
chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
Persistence of iron(II) in surface waters of the western subarctic Pacific
Persistence of iron surface waters the western subarctic Pacific
2014/4/21
The distribution of dissolved iron(II) [Fe(II)] was studied in surface waters of the western subarctic Pacific during the Subarctic Pacific Iron Experiment for Ecosystem Dynamics Study-II (SEEDS II) i...
Sinking particle properties from polyacrylamide gels during the KErguelen Ocean and Plateau compared Study (KEOPS): Zooplankton control of carbon export in an area of persistent natural iron inputs in the Southern Ocean
Sinking particle properties polyacrylamide gels during the KErguelen Ocean Zooplankton control area persistent natural iron inputs the Southern Ocean
2014/4/21
The Kerguelen ocean and plateau compared study (KEOPS) examined the origin of elevated phytoplankton biomass in naturally iron-fertilized waters over the Kerguelen plateau during midsummer (January-Fe...
Riverine input of macronutrients, iron, and organic matter to the coastal ocean off Oregon, U.S.A., during the winter
Riverine input macronutrients iron organic matter ocean off Oregon U.S.A. during the winter
2014/5/5
Three cross-shelf transects were conducted off northern Oregon in February, 2003, coincident with flooding of Coast Range rivers, to assess the riverine impact on coastal ocean biogeochemistry. During...
The FeL model of iron acquisition: Nondissociative reduction of ferric complexes in the marine environment
The FeL model of iron acquisition Nondissociative reduction ferric complexes marine environment
2014/5/4
Recently there has been recognition of the importance of reductive processes in the acquisition of iron by microorganisms in marine environments with Fe(III) reduction induced by either membrane-bound...
Terrestrial and aquatic ecosystems are intimately linked by the export of elements from watersheds. Although
export is influenced by land cover within watersheds, few models evaluate how the sp...
A role for manganese in superoxide dismutases and growth of iron-deficient diatoms
superoxide dismutases iron-defi cient diatoms
2014/5/19
We have discovered that coastal and oceanic diatoms require more manganese (Mn) to grow in iron (Fe) -deficient
than in Fe-sufficient seawater. At low inorganic concentrations, like those...
Iron requirements for dinitrogen- and ammonium-supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron:carbon ratios of field populations
Iron requirements nitrogen- and ammonium-supported growth cultures of Trichodesmium nitrogen fixation rates and iron field populations
2014/5/21
We quantified the relationships among the specific growth rate, intracellular iron content, and steady state iron uptake rate for cultures of the marine diazotrophic cyanobacterium Trichodesmium (IMS ...
Relationship of nitrogen isotope fractionation to phytoplankton size and iron availability during the Southern Ocean Iron RElease Experiment (SOIREE)
nitrogen isotope fractionation phytoplankton size iron availability the Southern Ocean Iron RElease
2014/5/20
The 15N composition of sediments has been used as a proxy for nitrate utilization in surface waters to assess the role of Southern Ocean export production in glacial/interglacial changes in atmospheri...
Iron-sulfur-phosphorus cycling in the sediments of a shallow coastal bay: Implications for sediment nutrient release and benthic macroalgal blooms
Iron-sulfur-phosphorus cycling in the sediments shallow coastal bay:sediment nutrient release benthic macroalgal blooms
2014/5/26
We conducted a study to determine the seasonal relationship between iron, sulfur, and phosphorus in the upper sediments and pore waters of a shallow intercoastal bay. From April 1999 to September 2000...
Biogeochemical effects of iron availability on primary producers in a shallow marine carbonate environment
iron availability primary producers shallow marine carbonate environment
2014/6/9
We completed a synoptic survey of iron, phosphorus, and sulfur concentrations in shallow marine carbonate sediments from south Florida. Total extracted iron concentrations typically were <50 μmol g-1 ...
