Assessing the potential for zinc limitation of marine primary production: proteomic characterization of the low zinc stress response in marine diatoms by Kellogg, Riss Morgan

“…I furthermore documented both the detection of ZCRPs in the Southern Ocean and the existence of Zn/Fe co-limitation within the natural phytoplankton population in Terra Nova Bay, demonstrating that Zn co-limitation can indeed occur in the field, even in high macronutrient waters. …”

The Global Zonally Integrated Ocean Circulation, 1992–2006: Seasonal and Decadal Variability by Heimbach, Patrick, Wunsch, Carl Isaac

“…In practice, little change is seen in the MOC and associated heat transport except very close to the sea surface, at depth near the equator, and in parts of the Southern Ocean. Variability in meridional transports in both volume and enthalpy is dominated by the annual cycle and secondarily by the semiannual cycle, particularly in the Southern Ocean. …”

Ventilation of the deep ocean constrained with tracer observations and implications for radiocarbon estimates of ideal mean age by Khatiwala, S, Primeau, F, Holzer, M

“…Our results show that ~. 40% and 26% of the global ocean was last in contact with the Southern Ocean and North Atlantic, respectively. Some 80% of the global deep ocean below 1500. m is ventilated from these high latitude regions. …”

Dispersal in the sub-Antarctic: King penguins show remarkably little population genetic differentiation across their range by Clucas, G, Younger, J, Kao, D, Rogers, A, Handley, J, Miller, G, Jouventin, P, Nolan, P, Gharbi, K, Miller, K, Hart, T

“…It is possible that migration could buffer king penguins against some of the impacts of climate change where colonies appear panmictic, although it is unlikely to protect them completely given the widespread physical changes projected for their Southern Ocean foraging grounds. Overall, large-scale population genetic studies of marine predators across the Southern Ocean are revealing more interconnection and migration than previously supposed.…”

Ra-226 and Ba concentrations in the Ross Sea measured with multicollector ICP mass spectrometry by Foster, D, Staubwasser, M, Henderson, G

“…The lack of surface depletion in either Ba or 226Ra differs from the pattern observed in the open Southern Ocean where concentrations increase with depth, suggesting that either the calcite-dominated productivity in the Ross Sea area does not remove 226Ra and Ba as effectively as opal-dominated productivity in the Southern Ocean, or that water column mixing in the Ross Sea is effective at the time scale of removal. © 2004 Elsevier B.V. …”

AN ULTRASTRUCTURAL STUDY OF THE ANTARCTIC CALANOID COPEPOD METRIDIA GERLACHEI GIESBRECHT, 1902. ADULT FEMALE by G.L. Mariottini, M. Feletti, P. Romano, A. Cadoni, A. Carli

“…In Antarctic waters low temperatures strongly affect the composition and structure of biocenosis and the occurrence of the Antarctic Convergence separates the Southern Ocean from surrounding waters. These characteristics led to the development of endemisms; therefore, the study of morphology, physiology, genetics and biochemical composition of Antarctic species are the basic elements to know their adaptive strate gies and to reconstruct evolutionary events. [...] …”

Connectivity in Asia : reviving the old Silk Road? by Rana, Pradumna B.

“…After enjoying a history of about 1600 years, the Silk Road had lost out to the Southern Ocean Corridor connecting Europe and Asia. But now there are signs that the old Silk Road is being revived.…”
