Distribution and reproductive ecology of the Antarctic octocoral Ainigmaptilon antarcticum in the Weddell Sea
The spatial distribution, density and reproductive ecology of Ainigmaptilon antarcticum was studied using samples (colonies) collected during the EASIZ (Ecology of the Antarctic Sea Ice Zone) cruises I, II, and III, (1996, 1998, and 2000). Samples were taken using Agassiz and bottom trawls between 1...
