The aim of this study is to understand how iconic Antarctic species such as penguins and seals have responded to past climate changes. We will use molecular tools to seek genetic signatures of past breeding refuges and understand how today's populations arose from those refugia.
To ensure the ecological sustainability of fisheries, management decisions must be based on clear, operational objectives and reliable assessment methods that are robust against uncertainties in our understanding of how the ecosystem functions, measurement error and natural variation.
Mesoscale cyclones over the Southern Ocean are not well known. A better knowledge is important for a range of human pursuits such as aviation and field safety. Additionally, low pressure systems are a vital component of the climate system by transporting heat and momentum towards high latitudes.
This project aims to use satellite & other data to enhance our knowledge of i) change & variability in the seasonality of East Antarctic sea ice coverage & the circumpolar distribution of fast ice, & factors responsible; & ii)…
Poa annua is an invasive weed of sub-Antarctic Islands, impacting on native biodiversity. Given high conservation values and threats from disturbance & climate change, the development of targeted control measures for invasive species is vital.
Manmade CO2 has increased ocean acidity by 30% and it is projected to rise 300% by 2100. Antarctic waters will be amongst the earliest and most severely affected by this increase. Microbes are the base of the marine food chain and primary drivers of the biological pump.
This study will utilise the technique of Radio Occultation (RO), where electromagnetic signals are refracted as they pass through the Earth’s atmosphere, to study the physical properties of the Antarctic atmosphere.
Antarctic sea ice is known to store key micronutrients, such as iron, as well as a suite of less studied trace metals in winter and which are rapidly released in spring.
Antarctic baleen whales were hunted to near extinction in the 20th Century. As populations recover and analytical approaches improve, there is an opportunity to describe the feeding grounds of Antarctic baleen whales and their behaviour used to exploit prey.
Antarctic krill is the key species of the Southern Ocean ecosystem. Its fishery is rapidly expanding and it is vulnerable to changes in climate. Australia has over a decade of krill abundance and distribution data collected off Eastern Antarctica.
