The algal osmolyte dimethylsulphoniopropionate (DMSP) and its enzymatic cleavage product dimethylsulphide (DMS) contribute significantly to the global sulphur cycle1,2,3, yet their physiological… (More)

In the oligotrophic North Atlantic and North Pacific, ultrafiltration studies show that concentrations of soluble iron and soluble iron-binding organic ligands are much lower than previously presumed… (More)

Surface waters of the subtropical Sargasso Sea contain dissolved inorganic phosphate (DIP) concentrations of 0.2 to 1.0 nanomolar, which are sufficiently low to result in phosphorus control of… (More)
Abstract The reproduction rates of 38 clones of marine phytoplankton were measured in media in which free cupric ion activity was controlled at different levels using a NTA-cupric ion buffer system.… (More)

The sub-optimal growth of phytoplankton and the resulting persistence of unutilized plant nutrients (nitrate and phosphate) in the surface waters of certain ocean regions has been a long-standing… (More)
Zinc is used extensively in the metabolism of higher organisms; cobalt’s usage is minimal. We found an unusual pattern of requirement for these metals in marine phyto,plankton in which the… (More)
The reproductive rates of 21 species of marine phytoplankton were measured in media in which free zinc, manganese, and iron ion activities were controlled at different levels using EDTA-trace metal… (More)
In Zn ion-buffered media, oceanic species (Thalassiosira oceanica and Emiliania hu.xZeyi) grew at near-maximal rates at the lowest free Zn ion concentration ((Zn2+) = lo- 12,3 M), whereas coastal… (More)
