Despite Antarctica’s sensitivity to climate change, few robust studies investigating the response of Antarctic vegetation to such changes exist.
The sub-glacial geology of East Antarctica remains one of the most mysterious frontiers on Earth.
The Southern Ocean Time Series provides world-leading automated observations from deep-ocean moorings between Tasmania and Antarctica (47ºS, 141ºE) of the exchanges of heat, water, carbon dioxide, and oxygen between the ocean and atmosphere…
The Southern Ocean is one of the most rapidly changing environments on earth.
The Intergovernmental Panel on Climate Change and the Commission for the Conservation of Antarctic Marine Living Resources have recently highlighted the need for regular assessments of change in Southern Ocean ecosystems.
The edges of the world's big ice sheets in Antarctica and Greenland hold the key to future sea level rise. Mass can be lost rapidly from these ice masses through icebergs breaking off, or through ice flowing into the ocean faster.
Stellaria media is an invasive palatable weed of sub-Antarctic islands, suppressed by pest herbivore (e.g. rabbit) grazing.
Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO), which is not surprising given this environment's unique nature.
The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hotspot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere.
The Totten Glacier is a large outlet glacier in East Antarctica that is thinning rapidly. It drains a very deep subglacial basin, which has the thickest ice covering the Antarctic landmass. Rapid thinning could cause accelerated melting of the Antarctic ice sheet and accelerated sea level rise.
