Could the Madagascar bloom be fertilized by Madagascan iron?† [PDF]
Journal of Geophysical Research: Oceans, 2015 AbstractIn the oligotrophic waters to the east of Madagascar, a large phytoplankton bloom is found to occur in late austral summer. This bloom is composed of nitrogen fixers and can cover up to ∼1% of the world's ocean surface area. Satellite observations show that its spatial structure is closely tied to the underlying mesoscale eddy field in the ...

Iron cycling during the decline of a South Georgia diatom bloom [PDF]
Deep-Sea Research Part II: Topical Studies in Oceanography, 2023 The Southern Ocean is the largest high nutrient low chlorophyll (HNLC) oceanic region, where iron limits phytoplankton growth and productivity and ultimately influences the Biological Carbon Pump (BCP). Natural exceptions to the HNLC regime occur where island wakes cause iron to be mixed into surface waters from sediments, enabling large, prolonged ...

Mesozooplankton response to iron enrichment during the diatom bloom and bloom decline in SERIES (NE Pacific) [PDF]
Deep-Sea Research Part II: Topical Studies in Oceanography, 2006 A mesoscale iron-fertilization experiment was carried out in the eastern subarctic Pacific during summer 2002. The iron patch was traced for 26 days after the enrichment, and the abundance and behavior of mesozooplankton was compared with those outside of the patch during the first half of the experiment (days 2–18) by Sastri and Dower [2006 ...

Glaciogenic iron transport pathways to the Kerguelen offshore phytoplankton bloom [PDF]
BiogeosciencesIn contrast to the average low biological productivity across most of the Southern Ocean, the Kerguelen region is one of the few subantarctic regions to host massive phytoplankton blooms, extending hundreds of kilometers offshore.

Enhanced viral production and virus-mediated mortality of bacterioplankton in a natural iron-fertilized bloom event above the Kerguelen Plateau [PDF]
Biogeosciences, 2014 Above the Kerguelen Plateau in the Southern Ocean natural iron fertilization sustains a large phytoplankton bloom over 3 months during austral summer. During the KEOPS1 project (KErguelen Ocean and Plateau compared Study1) we sampled this phytoplankton ...
