"Enhancement of Natural Carbon Sequestration in the Ocean
One approach to enhancing export production of carbon to the deep ocean is
via the addition of iron chelates (a micronutrient) to high nutrient, low
chlorophyll (HNLC) regions, in order to increase the drawdown of CO2 as a
result of stimulated phytoplankton blooms.  Another related technique would
be the addition of nitrates and phosphorus (macronutrients) to low nutrient,
low chlorophyll (LNLC) ocean regions.  The magnitude of these enhancements
to the biological pump and the depth of vertical transport are unknown, and
require additional research, as well as investigation into unknown
biological consequences from such perturbations, e.g., eutrophication, or
increasing number of unwanted events (toxic blooms)."

I recall a very interesting article (probably in the NY Times) that
may have been a feasable method.  There are vast stretches of ocean
with lower concentrations of algae.  Someone tried to fertilize them
with chemicals, and it worked.
Perhaps someone else has seen this idea and can shed more light on it.
