In the southeast corner water masses were typical of the Antarctic zone, showing a distinct subsurface temperature minimum of <2.5°C. Total integrated chl-a concentration during the survey ranged from 4.15 to 22.81 mg chl-a m[superscript (-2)], with the highest concentrations recorded at stations occupied in the frontal region. These data suggest that the region of the South-West Indian Ridge represents not only an area of elevated biological activity but also acts as a strong biogeographic barrier to the spatial distribution of zooplankton.]]> Thu 25 Apr 2024 15:46:55 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6832 Thu 25 Apr 2024 15:46:11 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6966 0.05). The zooplankton community was dominated, numerically and by biomass, by mesozooplankton comprising mainly copepods of the genera, Oithona,Paraeuchaeta, Pleuromamma, Calanus and Clausocalanus. An exception was recorded at those stations in the region of the front where the tunicate, Salpa thompsoni, dominated the total zooplankton biomass.]]> Thu 25 Apr 2024 15:42:47 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:6881 Thu 25 Apr 2024 15:42:12 SAST ]]>
