We report the first observations of simultaneous high-latitude inter-hemispheric F-region neutral wind fields by combining the 630 nm optical measurements from two scanning Doppler imagers and three Fabry-Perot interferometers for a period exceeding 5 hours on 3 October 2008.
All-sky imaging Fabry-Perot spectrometers can provide two dimensional maps of thermospheric wind and temperature fields over a circular region spanning around 1400 km in diameter at F-region heights, or about half this in the E-region.
Trace elements often limit phytoplankton growth in the ocean, and the quantification of particulate forms is essential to fully understand their biogeochemical cycling. There is presently a lack of reliable measurements on the trace elemental content of marine particles…
We report the first observations of E-region neutral wind fields and their … interaction with auroral arcs at meso-scale spatial resolution during … geomagnetically quiet conditions at Mawson, Antarctica. This was achieved by … using a scanning Doppler imager…
In situ chemical oxidation (ICO) has been identified as a potential technology for the remediation of petroleum hydrocarbon contaminated sites in Antarctica.
A comparison is made of results for barotropic, surface and abyssal flows during the formation and … passage of a warm-core ring in the East Australian Current. The barotropic velocities are estimated from … sea-floor measurements of the horizontal electric field, which is induced by water motion.
In the Indian Ocean subtropical gyre, historical temperature, salinity, and oxygen data with a median date of … 1962 are compared with a hydrographic section taken at a mean latitude of 328S in October–November 1987.
The response of oceanic phytoplankton to … climate forcing in the Arctic Ocean has attracted … increasing attention due to its special geographical … position and potential susceptibility to global warming. Here, we examine the relationship between satellitederived …
Delta15N signatures of fossil peat were used to interpret past ecosystem processes on tectonically active subantarctic Macquarie Island. By comparing past vegetation reconstructed from the fossil record with present day vegetation analogues, our evidence strongly suggests that changes in the ?
A 5 yr field experiment was carried out comparing the effects of Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W40), used synthetic lubricant (used Mobil 0W40) and a biodegradable lubricant (Titan GT1) on Antarctic benthic microbial communities.
The Global Atmosphere Watch of WMO includes several stations in Antarctica that keep a close eye on the ozone … layer during the ozone hole season. Observations made during the ozone holes from 2003 to 2009 will be compared … to each other and interpreted in light of the meteorological conditions.
In 2001 a unique field experiment was established to compare the longevity and effects of four different oils on the Antarctic benthic ecosystem. Clean sediment was collected, spiked with one of the oils: Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W-40)…
