Growth physiology and fate of diatoms in the ocean: a review
Diatoms are a major component of phytoplankton community. They tend to dominate under natural high-nutrient concentrations, as well as during artificial Fe fertilisation experiments. They are mainExpand

Growth rates, half‐saturation constants, and silicate, nitrate, and phosphate depletion in relation to iron availability of four large, open‐ocean diatoms from the Southern Ocean
Four large, open-ocean diatoms from the Southern Ocean (Actinocyclus sp., Thalassiosira sp., Fragilariopsis kerguelensis, and Corethron pennatum) were grown in natural (low iron) Southern oceanExpand

Effect of natural iron fertilization on carbon sequestration in the Southern Ocean
The availability of iron limits primary productivity and the associated uptake of carbon over large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes in itsExpand

Synthesis of iron fertilization experiments: From the iron age in the age of enlightenment
Comparison of eight iron experiments shows that maximum Chl a, the maximum DIC removal, and the overall DIC/Fe efficiency all scale inversely with depth of the wind mixed layer (WML) defining theExpand

Cell death in phytoplankton: correlation between changes in membrane permeability, photosynthetic activity, pigmentation and growth
Different stages of the automortality in phytoplankton have been studied applying flow cytometry. These stages are, in order of expression: (1) compromised cell membranes, (2) degradation of theExpand

Growth rates of large and small Southern Ocean diatoms in relation to availability of iron in natural seawater
Blooms of large diatoms dominate the CO2 drawdown and silicon cycle of the Southern Ocean in both the past and present. The growth of these Antarctic diatoms is limited by availability of iron (andExpand

Physiological responses of three species of marine pico-phytoplankton to ammonium, phosphate, iron and light limitation
Abstract Experiments were conducted with three species of marine pico-phytoplankton: Synechococcus sp. (CCMP 839), Pelagomonas calceolata (CCMP 1756) and Prasinomonas capsulatus (CCMP 1617) in orderExpand

Significant portion of dissolved organic Fe complexes in fact is Fe colloids
Vertical distributions of iron and iron binding ligands were determined in 2 size classes (dissolved 200 kDa–< 0.2 μm) were inferred as the difference between the dissolved and soluble fractions.Expand

Elevated CO2 and Phosphate Limitation Favor Micromonas pusilla through Stimulated Growth and Reduced Viral Impact
ABSTRACT Growth and viral infection of the marine picoeukaryote Micromonas pusilla was studied under a future-ocean scenario of elevated partial CO2 (pCO2; 750 μatm versus the present-day 370 μatm)Expand

A comparison of iron limitation of phytoplankton in natural oceanic waters and laboratory media conditioned with EDTA
The solubility of iron in oxic waters is so low that iron can be a limiting nutrient for phytoplankton growth in the open ocean. In order to mimic low iron concentrations in algal cultures,Expand
