Southern Ocean Iron Enrichment Experiment: Carbon Cycling in High- and Low-Si Waters
The availability of iron is known to exert a controlling influence on biological productivity in surface waters over large areas of the ocean and may have been an important factor in the variation ofExpand

Particle export during the Southern Ocean Iron Experiment (SOFeX)
We studied the effect of iron addition on particle export in the Southern Ocean by measuring changes in the distribution of thorium-234 during a 4-week iron (Fe) enrichment experiment conducted inExpand

Photosynthetic maximum quantum yield increases are an essential component of the Southern Ocean phytoplankton response to iron
It is well established that an increase in iron supply causes an increase in total oceanic primary production in many regions, but the physiological mechanism driving the observed increases has notExpand

Dissolved O2/Ar and other methods reveal rapid changes in productivity during a Lagrangian experiment in the Southern Ocean
[1] We use continuous and discrete measurements of the dissolved O2/Ar ratio in the mixed layer to investigate the dynamics of biological productivity during the Southern Ocean Gas ExchangeExpand

An assessment of optical properties and primary production derived from remote sensing in the Southern Ocean (SO GasEx)
[1] Optical properties and primary production were measured during the Southern Ocean (SO) Gas Exchange Experiment (GasEx) (March–April 2008). To assess and evaluate these properties derived fromExpand

In situ activity of a dominant Prochlorococcus ecotype (eHL-II) from rRNA content and cell size.
In the open ocean genetically diverse clades of the unicellular cyanobacteria Prochlorococcus are biogeographically structured along environmental gradients, yet little is known about their in situExpand

Resolving the ocean's euphotic zone
Measurements of net primary production (P) combined with calculated estimates of phytoplankton respiration (Rp) and gross primary production (G) are used to determine the depth of the ocean'sExpand

Iron and silicic acid effects on phytoplankton productivity, diversity, and chemical composition in the central equatorial Pacific Ocean
A microcosm nutrient-amendment experiment using central equatorial Pacific Ocean (0u, 140uW) mixed-layer waters was conducted to determine biogeochemical controls on phytoplankton with an emphasis onExpand
