Changes in atmospheric circulation over the past decades have enhanced the wind-driven inflow of warm ocean water onto the Antarctic continental shelf, where it melts ice shelves from below. Atmospheric circulation changes have also caused rapid warming over the Antarctic Ice Sheet, and contributed to declining sea-ice cover. Antarctic seawater ecosystems are expected to show particular sensitivity and rapid responses related to the variation of the environmental climatic conditions. The thesis topic is to identify the influence of environmental parameters on the variability of zooplankton abundance and composition in the Ross Sea in order to verify the possible occurrence of a regime shift. The proposed activities include the acquisition of laboratory skills for the treatment and analysis of samples collected by time-series sediment traps through microscopic examination to estimate the composition, classification and finally to estimate the flows of zooplankton communities.
