Chesterton, A. (2017). Sea ice, zooplankton, and fish interactions at a coastal Antarctic site..
Abstract: Each year the total surface area of sea ice of Antarctica continues to decline due to
warming climates, which might be starting to indicate consequences for sea ice interface
dependent organisms. Species in the coastal waters of Antarctica are not readily studied, but are
proving to have more of an importance in the Antarctic marine ecosystems than previously
thought. This study analyzes the inter-annual differences among two consecutive summer
seasons (2015/2016 and 2016/2017) in the coastal regions near Dumont d’Urville station,
Antarctica. The purpose of this study is to determine if a continued loss of Antarctic sea ice will
effect species that depend on the sea ice interface, such as Paralabidocera antarctica and
Pagothenia borchgrevinki. Specifically, this study compared zooplankton species found in
vertical hauls, chlorophyll-a concentrations in both the water column and the sea ice, water
temperature, and sea ice dynamics, during both summer seasons, then compared these results
with zooplankton species variation in the gut contents of larval Pagothenia borchgrevinki.
Results from this study show that there is a food chain from ice algae, to Paralabidocera
antarctica, to Pagothenia borchgrevinki and that Paralabidocera antarctica and Pagothenia
borchgrevinki both depend highly on the sea ice interface of the Antarctic coastal waters as the
abundance of Paralabidocera antarctica and the feeding habits of Pagothenia borchgrevinki
fluctuate based on changes in this habitat.

Gomm E. (2016). Zooplankton community assemblages and trophic links in a nearshore zone of the Adélie Basin, East Antarctica. .
Abstract: Distribution, and abundances of the zooplankton community at site Jacobsen (40 m depth) near Dumont d’Urville Station (-66.39oS, 140.00oE) in the East Antarctic, Adélie Basin area are reported. The sampling period went from the 15th November 2015 to the 3rd of February 2016. Samples were taken in the water column over the course of the sea ice break-up and subsequent spring phytoplankton bloom. Environmental variables such as chlorophyll a, air temperature, salinity and temperature in the water column were measured and later sea ice extent and concentration data was acquired to make informed conclusions regarding the presence and abundance of zooplankton species. Oithona similis, Oncaea curvata, and Drescheriella glacialis were species found in high abundances. D. glacialis in particular was found within the sea ice.
Stable isotope analysis was conducted on samples of seawater particulate organic matter (POM), ice core POM, Oithona similis, Oncaea curvata, Pleuragramma antarcticum larvae, and adult Trematomus newnesi, Trematomus bernacchii, and Notothenia coriiceps. Where necessary samples were lipid extracted of lipid corrected to give appropriate ????13C and ????15N values. Known trophic enrichment factors were then used to construct a possible food chain in the lower trophic levels of a coastal Antarctic site.
