McMurdo Sound is representative of large areas of the Southern Ocean            which are seasonally or permanently covered by sea-ice.  Inputs of              microalgal carbon into McMurdo Sound are seasonally episodic and appear         to be strongly influenced by inputs from sea ice microbial communities          and advection from the Ross Sea.  The hypothesis of this project is that        the trophic role of nano- and microzooplankton reflects the episodic            nature of primary production in this system.  Using McMurdo Sound as a          study site, the research will examine seasonal and spatial variation in:        1)  the distribution of nano- (2-20 um) and micro- (20-200 um)                  zooplankton, microalgae and bacteria.  2)  growth rates of                      microzooplankton.  3)  grazing impact of nano- and microzooplankton             communities on algae and bacteria.                                                                                                                              Dominant bactivores in this system will be identified and the use of            dissolved free amino acids and detritus as nutritional sources for              individual microzooplankton species evaluated.  Results of this study           will improve the understanding of the role of microbial food webs in the        cycling of carbon in ice-covered regions of the Southern Ocean.
