TY - RPRT AU - Chesterton, A. PY - 2017// TI - Sea ice, zooplankton, and fish interactions at a coastal Antarctic site. N2 - 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. N1 - exported from refbase (http://publi.ipev.fr/polar_references/show.php?record=6816), last updated on Wed, 10 Jul 2024 13:40:29 +0200 ID - Chesterton2017 ER -
