Category 1: Peer-reviewed literature

We conducted a scanning electron microscopic survey of morphological variations in the … calcareous nanoplankton species Emiliania huxleyi in Southern Ocean surface water samples … collected along a transect from 43 to 64° S and 141 to 145° E during November 2001, October to … February 2002/2003…

A specific Bio-optical primary production model tuned to the Kerguelen Iron-enriched region. Eos Transactions AGU, Ocean Sciences Meeting Supplement., 2006 (Ref: 12622)
Category 3: Abstract

HPLC-pigment measurements, Production vs Irradiance and daily primary production experiments were carried out on the Kerguelen Plateau during the KEOPS cruise in January and February 2005. The respective contribution of three phytoplankton size classes, namely micro- (> twenty micron)…

Photosynthetic parameters, size-fractionated chlorophyll and primary production durintg the KEOPS Expedition east of Kerguelen Island January-February 2005. Eos Transactions, AGU, Ocean Sciences Meeting Supplement., 2006 (Ref: 12619)
Category 3: Abstract

: P vs E experiments determining photosynthetic parameters and daily primary production were carried out east of Kerguelen Island during the KEOPS cruise in January and February 2005. The Kerguelen Plateau region is naturally enriched with iron, while deeper waters (>1000m) nearby may not be.

Seasonal dynamics of Southern Ocean protistan populations along 140ºE transect, 2002-2005. Abstracts of the SCAR Open Science Conference, Hobart, 12-14 July 2006., 2006 (Ref: 12509)
Category 3: Abstract

Studies of carbon flux and ecosystem processes require models of the population dynamics … of phytoplankton and other microbial organisms, but with over 500 protistan species known to … inhabit these waters, it is not feasible to model them individually. Instead…

Control of phytoplankton growth by iron supply and irradiance in the subantarctic Southern Ocean: Experimental results from the SAZ Project Journal of Geophysical Research, 2001 (Ref: 10280)
Category 1: Peer-reviewed literature

The influence of irradiance and iron (Fe) supply on phytoplankton processes … was investigated, north (47S, 142E) and south (54S, 142E) of the Subantarctic Front in … austral autumn (March 1998). At both sites, resident cells exhibited nutrient stress (F v / … Fm  0.3).

Control of phytoplankton growth by iron and silicic acid availability in the subantarctic Southern Ocean: Experimental results from the SAZ Project Journal of Geophysical Research, 2001 (Ref: 10284)
Category 1: Peer-reviewed literature

Subantarctic Southern Ocean surface waters in the austral summer and autumn are characterized by high concentrations of nitrate and phosphate but low concentrations of dissolved iron (Fe, ~0.05nM) and silicic acid (Si, <1µM).
