The Polar regions are considered to be particularly susceptible to the effects of climate change. Although there is evidence for warming in the Antarctic during the last century, few long-term ecological monitoring programmes have been initiated in this region. Zooplankton have been demonstrated to be excellent environmental indicators and in 1991 a Continuous Plankton Recorder (CPR) survey was established in the Southern Ocean south of Australia for monitoring purposes. Using data collected between October 2001 and March 2002 this thesis aimed to provide baseline data for the Southern Ocean CPR survey, and the first high resolution (‚ÄövÑvÆ 5 nm), ocean-basin scale sampling of zooplankton communities south of Australia. As a primary step the sampling characteristics of the CPR were investigated by direct comparison of depth integrated NORPAC net samples with CPR samples (average depth ‚ÄövÑvÆ 10.5 m). Data were collected on a repeat transect along 140¬¨‚àûE, between November and December 2001. Species ...
