A Lowell DPS-4 digital ionosonde has operated at the Australian Antarctic polar cap station of Casey (-80.6 deg CGM latitude) since early 1993.
A Lowell DPS-4 digital ionosonde has operated at the Australian Antarctic polar cap station of Casey (-80.6o CGM latitude) since early 1993. During that time the DPS-4 has been operated in a routine mode to obtain an extended database of background ionospheric drift measurements [1].
This work employed manipulative experiments, in conjunction with statistical power analysis, to quantify the effects of human activity on Adélie Penguins (Pygoscelis adeliae) during the incubation and guard phases of their breeding cycle. Two main questions were addressed: (a) What is the minimum…
Two series of mutant polypeptides of the type I, 37 residue winter flounder antifreeze protein have been synthesized and analyzed by nanoliter osmometry, the ice hemisphere test, measurement of ice growth hysteresis and circular dichroism spectroscopy.
Bathymetric, sidescan sonar and high-resolution seismic data indicate that the shelf off Mac. Robertson Land, East Antarctica is deeply eroded by glaciers and currents. Basement is exposed over wide areas. Data available include MCS and 3.5 kHz obtained by Stagg (1985) in 1982 (see OBrien et al.…
Bryum argenteum sensu lato is a cosmopolitan moss found in many countries of the world, and is one of only a few moss species present in continental Antarctica. We have used RAPD (Random Amplified Polymorphic DNA) technology to investigate how this moss has colonised and spread in Antarctica…
Islands in the Southern Ocean are susceptible to several land-based threats, including invasion by human-introduced biota, disturbance of wildlife or sites, and various forms of pollution.
