Cobalt (Co) is a scarce but essential micronutrient for marine plankton in the Southern Ocean and coastal Antarctic seas, where dissolved cobalt (dCo) concentrations can be extremely low. This study presents total dCo and labile dCo distributions mea

Phaeocystis antarctica is an important phytoplankter of the Ross Sea where it dominates the early season bloom after sea ice retreat and is a major contributor to carbon export. The factors that influence Phaeocystis colony formation and the result

We report the distribution of cobalt (Co) in the Ross Sea polynya during austral summer 2005–2006 and the following austral spring 2006. The vertical distribution of total dissolved Co (dCo) was similar to soluble reactive phosphate (PO43−), with

Iron availability and temperature are important limiting factors for the biota in many areas of the world ocean, and both have been predicted to change in future climate scenarios. However, the impacts of combined changes in these two key factors on

The late stage of the North East Atlantic (NEA) spring bloom was investigated during June 2005 along a transect section from 45 to 66° N between 15 and 20° W in order to characterize the contribution of siliceous and calcareous phytoplankton groups

The influence of iron on phytoplankton biogenic sulfur production, physiological status, and community structure in the Peruvian Upwelling System was investigated in September 2000. Vertical profiles of particulate dimethylsulfoniopropionate (DMSPp)

Rates of phytoplankton growth and production were measured with 14C techniques at stations near the Hawaiian Islands and at about 28°N, 155°W in the North Pacific subtropical gyre during August and September 1985. Ratios of light-saturated assimila

Phytoplankton assemblages of the Ross Sea are generally dominated by two functional groups: diatoms and haptophytes ( Phaeocystis antarctica ). Within this “normal” pattern of dominance, there is a substantial amount of temporal (over months, sea
