Summary
Abstract:

The Ross Sea is believed to contributes a huge portion (~1/3) of the primary productivity of the Southern Ocean and is home to a similar large portion of the top predators (e.g. 38% of Adelie, 28% of Emperor penguins) of the Antarctic sea ice ecosystem. The trophic pathways in this system are complex in both space and time. One scenario for the Ross Sea ecosystem is that diatoms are grazed by ...


 This collaborative research sets out to use an autonomous glider, equipped with a range of sensors, and informed by satellite chlorophyll imagery to be combined with 3-dimenisonal active penguin tracking to their preferred foraging sites. The effect of localized grazing pressure of krill on the appearance and disappearance of algal blooms will also be followed. Overall the objective of the research is to reconcile and explain several years of the study of the foraging habits and strategies of (top predator) penguins at the Cape Crozier site (Ross Island), with the dynamics of krill and their supporting algal food webs. The use of a glider to answer a primarily ecological questions is subject to moderate to high risk, and is potentially transformative.
