| Abstract: | The influence of environmental factors on the horizontal community structure of zooplankton over the southern Kerguelen Plateau was investigated during summer in 2016. Zooplankton abundance ranged from 1490 to 363,484 ind. 1000 m(-3), with highest numbers observed in the eastern and central areas. Based on cluster analysis the zooplankton were divided into six groups (A-F), and these were only distinguished based on water masses and frontal systems. Groups A to C had abundant zooplankton and were consistent with areas of high chlorophyll a concentration. Group D represented low abundance near the southern Antarctic Circumpolar Current front, while group E was clustered south of the Southern Boundary and group F comprised two stations to the east of the Fawn Trough. Generalised linear model (GLM) highlighted both fronts and chlorophyll a concentration as drivers of overall zooplankton distribution. However, the population structures of key species were more likely a result of species-specific life cycles rather than water masses and frontal systems. |
