Over the past two decades drifting sea-ice buoys have been used by the Australian Government Antarctic Division [AGAD] to observe sea-ice drift and deformation. Initial deployments often used single buoys … to resolve the large-scale characteristics of Antarctic sea-ice drift.
Australia’s Antarctic territory contains several hydrocarbon-contaminated sites of varying size and severity as a result of fifty years of human activities in the region. Contaminated site remediation in Antarctica is more challenging than in Australia.
New evidence regarding the origins of the Crustacea of Antarctic lakes is reviewed. Palaeolimnological data indicates that the cladoceran Daphniopsis studeri has been present in Lake Reid, Larsemann Hills, for over 120 000 yr.
The preservation of tardigrade eggs and exuviae in Antarctic lake sediments provided an opportunity to assess post-glacial … colonisation and Holocene tardigrade dynamics on the southern continent. Tardigrade eggs were recovered from five lakes…
Remains of tardigrades have rarely been … reported to preserve in sediments, resulting in the … absence of important ecological and biogeographic … information that they could provide. However…
Two species of Nematoceras (Orchidaceae) from subantarctic Macquarie Island are characterised, illustrated and details of distribution and ecology are provided. Nematoceras sulcatum … M.A.Clem. et D.L.Jones…
Spatial Data Infrastructures (SDIs) have been developing in some countries for over 10 years but still suffer from … having a relatively small installed base. Most SDIs will soon converge around a service-oriented-architecture (SOA)…
Populations of Southern Rockhopper ( Euduptes chrysocome chrysocome … ) and Macaroni ( E. chrysolophus … ) Penguins at key breeding sites in the Southern Hemisphere have declined substantially in the past 50 years, but … their statuses at important breeding sites in southern Chile are poorly known.
On 20 January 2005 the sun produced the highest intensity of relativistic … solar particles observed at Earth in 50 years. The sea-level increase at Terre Adelie … (~46 X in 1 minute data) was slightly less than in 1956 (Leeds ~47 X in 15 minute … data).
Blue-dyed bait is a seabird bycatch mitigation technique which is assumed to reduce the … contrast between the bait and the ocean background making baits visually cryptic to seabirds. We tested this assumption in two ways. First, using measured spectral profiles of blue-dyed … baits (fish and squid)…
Abstract. An auroral westward flow channel (AWFC) is … a latitudinally narrow channel of unstable F-region plasma … with intense westward drift in the dusk-to-midnight sector … ionosphere. AWFCs tend to overlap the equatorward edge of … the auroral oval…
A recent review by Ainley et al. has suggested that recent investigations of the ecological structure … and processes of the Southern Ocean have “almost exclusively taken a bottom-up, forcing-by-physicalprocesses … approach relating individual species’ population trends to climate change”.
A high-latitude tide basis function that describes the major migratingand non-migrating components of the semidiurnal and … diurnal tide can be fitted to wind data using linear least-squares fitting techniques. MF radars at Davis (695, 78E), Syowa (695, 40E), Rothera (685, 68W) and Scott Base (785…
