"Vertical and horizontal distribution of iron and aluminum in the polar frontal zone of the southern ocean"

The goal of this project is to produce a comprehensive set of data for the reactive trace metals iron and aluminum in the Polar Frontal Zone of the Southern Ocean Process Study during the four proposed cruises. Iron and aluminum will be determined on board on samples collected at the various hydrographic stations occupied during the cruises. In addition, deployment of a towed surface sampler during the transits between stations will be used to map distributions in the surface waters of the regions. Shorebased analyses of Be and Mn will be completed on a subset of stored water samples.
