TL;DR: The findings of these 12 FeAXs reveal that iron supply exerts controls on the dynamics of plankton blooms, which in turn affect the biogeochemical cycles of carbon, nitrogen, silicon, and sulfur and ultimately influence the Earth climate system.

TL;DR: In this paper, a comparison of eight iron experiments shows that maximum Chl a, the maximum DIC removal, and the overall DIC/Fe efficiency all scale inversely with depth of the wind mixed layer (WML) defining the light environment.

TL;DR: In the Canada/US 1994 Arctic Ocean Section, algal biomass (Chlorophyll a) and primary production were measured in the water column, at the ice-water interface and in the bottom 24 cm of the sea ice along a transect from the Chukchi Sea to the Nansen Basin via the North Pole as discussed by the authors.

TL;DR: In this paper, a database of 15,617 point measurements of dimethylsulfide (DMS) in surface waters along with lesser amounts of data for aqueous and particulate DMS, chlorophyll concentration, sea surface salinity and temperature, and wind speed has been assembled.

TL;DR: The depletion of silicic acid and the inefficient transfer of iron-increased POC below the permanent thermocline have major implications both for the biogeochemical interpretation of times of greater iron supply in the geological past, and also for proposed geo-engineering schemes to increase oceanic carbon sequestration.
