A climatological mean distribution for the surface water pCO2 over the global oceans in non-El Niño conditions has been constructed with spatial resolution of 4° (latitude) ×5° (longitude)…
A new all-sky imaging Fabry-Perot spectrometer … has been installed at Mawson station (67360 S, 62520 E), Antarctica. This instrument is capable of recording independent … spectra from many tens of locations across the sky simultaneously. Useful operation began in March 2007…
A local scale, time dependent three-dimensional … model of the neutral thermosphere was used to test the applicability … of two previously published empirical relations between … thermospheric vertical wind and velocity divergence, i.e., those due to Burnside et al. (1981) and Brekke (1997).
Temperature data from the COSMIC GPS-RO … satellite constellation are used to study the distribution and … variability of planetary wave activity in the low to midstratosphere … (15–40 km) of the Arctic and Antarctic from … September 2006 until March 2009.
With the development of next generation aircraft designs capable of ultralong-range flight and … extended flight endurance…
Two endemic orchid species, Nematoceras dienemum and N. sulcatum, are known from sub-Antarctic Macquarie Island. Several additional orchid populations on the island are reported and cleistogamy is documented in N. dienemum for the first time. The known population sizes…
Species of the genus Pyramimonas (Prasinophyceae) are a common, widespread, but minor component of the Antarctic marine phytoplankton. They are … often associated with the seasonal sea-ice environment. Pyramimonas gelidicola … (McFadden, Moestrup & Wetherbee, 1982)…
1. Although marine protected areas (MPAs) are often established to protect threatened top-order … predators, there is a paucity of data that can be used to evaluate their efficacy in achieving this … purpose. 2.
Atmospheric ionization during Solar Proton Events (SPE) has traditionally … been modeled using top-of-atmosphere (TOA) particle fluxes measured by near- … Earth spacecraft, and as a consequence the modeling has been restricted to … particle energies below ¡ 500 MeV. However…
Recent model calculations have attempted to quantify the contribution of … major energetic solar cosmic ray (SCR) events to 10Be production.1,2 In this … study we compare modeled 10Be production by SCR events to measured … 10Be concentrations in a Law Dome snow pit record.
Quantifying the contribution of solar variability to past and present climate change has been … an important and controversial aspect of climate research.
Superposed epoch analysis (SEA) was used to examine ionospheric drift velocities measured by a digital … ionosonde located at the mid-latitude station Bundoora (145.11E, 37.71S geographic), near Melbourne. The control times for the SEA were the times of cloud-to-ground (CG)…
The remediation of the Thala Valley landfill, Casey Station, East Antarctica, is part of efforts to … clean-up contaminated sites associated with the Australian Antarctic Program. These sites, ranging from abandoned rubbish dumps to fuel spills…
