Variability in the inter-island environment of the Prince Edward Islands (Southern Ocean)

摘要: Variability in the oceanographic parameters and macrozooplankton micronekton composition, densities distributional patterns were investigated during a repeat survey conducted between Prince Edward Islands April 1998. Results of this study demonstrated occurrence pronounced water pulses along inter-island trench. The location Subantarctic Front to north island plateau, through its interactions with group, appeared have marked effect on mesoscale dynamics physical biological around islands. Seawater temperature salinity accounted for >40% variation zooplankton distribution trench studies. A total 41 macroplankton taxa, consisting subantarctic, subtropical Antarctic species, identified. Numerical analyses revealed two major groupings stations corresponding an offshore inshore region. Although there was no evidence quantitative differences surveys, plankton biomass at least three- eightfold higher than surveys. importance carrying stocks large islands be minimal, time when investigation took place.
