When the first scientific voyages went to the Southern
Ocean, high levels of living biomass were observed in the
vicinity of islands. Hart (1942) was the first to mention that
the abundant biomass might be due to the release of oligoelements
like iron from the island. This hypothesis,
however, remained unverified for more than half a century
because of the experimental difficulties in properly
manipulating water with subnanomolar iron concentrations.
When John Martin formulated the iron hypothesis
(Martin, 1990) and provided the first supporting evidence
of it, he also suggested using the chlorophyll plume
observed westward of the Galapagos Island in the
Equatorial Pacific as a natural iron fertilization experiment.
