Antarctic landfast sea ice is an integral component of coastal and nearshore ecosystems, providing bottom-ice habitats that harbour some of the most productive marine microalgal communities on Earth. Ice algal biomass is driven by the spatio-temporal dynamics of snow and sea-ice covers…
The use of satellite tags has yielded important information to better understand cetacean ecology and to improve cetacean conservation. However, tag deployment duration has been highly variable and typically shorter than their battery life on most large whale species. Between 2011 and 2018…
Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, whales have once again become summer visitors, with the southern right whale (SRW) the most commonly reported species until 2011. Here…
Hundreds of large whales have been tracked using consolidated (Type-C) satellite tags, yet there have been few studies on their impacts on whale health. In 2011, we initiated the first study designed to evaluate the effects of these tags on a baleen whale. Between 2011 and 2018…
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean…
Considered from a functional ecological perspective, Antarcticas present-day terrestrial biota is the product of two sets of limiting factors: the continents isolation from sources of immigrant propagules and the severe environmental stresses to which successful immigrants are exposed.
The ice-free habitats of continental Antarctica are among the most geographically isolated on Earth. Colonization of Antarctica requires the immigration of dissemules from distant biotic sites across large distances of snow or open ocean.
The Antarctic continent covers an area of nearly 14 million square kilometres, representing one-sixteenth of the Earths land surface. Ninety-eight percent of this area is covered by ice. The remaining 2% comprises widely scattered patches of rock and mineral terrain surrounded by snowfields…
