Summer Variation of Zooplankton Community on Coastal Environment of Admiralty Bay, King George Island, Antarctica

Abstract

is study aims to provide data on the abundance and distribution of zooplankton related to oceanographic

Pteropods, Chaetognaths and Salps in Admiralty Bay, King George Island, Antarctica

“…According to Alldredge & Madin (1982), they are mainly lter feeders of particles between 4 -16 µm, through the production of mucus nets. Studies carried out in the stations have indicated that copepods and microalgae are abundant, especially diatoms and dino agellates (Tenenbaum et al, 2011;Tenório et al, 2011;Kern et al, 2012), thus indicating an association between the abundance of these species and the presence of aliaceans in these places.…”

“…In relation to the studied groups, low pteropod density was observed in the summer of 2009/2010 in Admiralty Bay inner region, with two species identi ed (Limacina helicina and Clione limacina). Kittel et al (2001) identi ed two species of pteropods (Limacina helicina and has been observed in this place (Froneman et al, 1966;Tenenbaum et al, 2011;Tenório et al, 2011;Kern et al, 2012). Studies by Gilmer & Harbison (1991) observing the diet of Limacina helicina in the Arctic region indicated that the main items of the diet of these organisms are small copepods and microalgae (diatoms and dino agellates).…”
