The abundance and diversity of ostracodes
in Zone IIIa was high with the average abundance of 50 per layer, which were dominated by Limnocythere.
After corning and comporting big fractions of sediments (particles higher than 125 micron), 50 g of samples were countered in order to investigate the Ostracodes
existed in sediments.
Collection of the ostracodes
within sediment samples was completed with aD-frame net.

Modern benthic ostracodes
from Lutzow-Holm Bay, East Antarctica: paleoceanographic, paleobiogeographic, and evolutionary significance.
10 species of larger forams including age diagnostic Miscellanea miscella, Lockhartia haimei were recorded along with Milliolids, Planktons as well as Gastrpods, Pelecypods, Ostracodes
, Dasycladacean algae, Echinoderms and Sponges were also observed.
Diatoms are generally a dominant group in the phytoplankton, whereas cladocerans, copepods and ostracodes
are typically the main zooplankters in fresh waters (Dole-Olivier et al.
