Shipboard studies were performed for testing the classical hypothesis that Antarctic
phytoplankton suffers from a deficiency of Fe. In a suite of 5 experiments over 8 to 12 d …

In shipboard experiments, addition of Fe to samples from Antarctic shelf waters or from deep
waters close to the shelf break did not have any detectable effect on phytoplankton …

Enrichment experiments were performed in the Ross Sea to test the hypothesis that iron
deficiency is responsible for the phytoplankton's failure to use up the luxuriant major nutrient …

The physiological responses of plankton to iron enrichment were investigated in
experiments performed in 20-1 culture vessels. Natural phytoplankton communities in sea …

In March 1998 we measured iron in the upper water column and conducted iron‐and
nutrient‐enrichment bottle‐incubation experiments in the open‐ocean Subantarctic region …

There has been considerable debate about both the mechanisms controlling primary
production, and the interpretation of data from Fe-enrichment experiments conducted in high …

The effect of iron on phytoplankton physiology in a scarcely investigated part of the Pacific
region of the Southern Ocean was studied during an expedition aboard RV'Polarstern' …

Excess major nutrients occur in offshore areas ranging from the tropical equatorial Pacific to
the polar Antarctic. In spite of the great ecological differences in these environments, we …

The first Southern Ocean Iron RElease Experiment (SOIREE) was performed during
February 1999 in Antarctic waters south of Australia (61° S, 140° E), in order to verify …

During the European Polarstern Study (EPOS 1988/1989) in the Weddell and Scotia Seas,
five series of metal enrichment experiments were carried out with natural plankton …
