What is it about?
The study is a reanalysis of a dataset constituted by fast ice cores collected in bays of the Victoria Land Coast (Ross Sea) in 1997, 1999 and 2004. The biogeochemical data concerning the ice are compared to those relevant to snow, platelet ice, interstitial water and under-ice seawater. The effects of meteorological conditions are also analysed using time series (1996-2005) obtained by automated stations.

Why is it important?
The inverse application of Zubov’s Law is used to estimate the timing of formation of the coastal ice. Strong Katabatic winds often cause ice break out in July-August, determining an interannual variability of its thickness and extension. In spring, fast changes of the ambient conditions modulate the physical structure of ice and its chemical and biological characteristics. Spring activity of ice biomass causes a large accumulation of dissolved organic matter that can be released in the sea.
