Total dissolvable iron (TDFe) was measured in sections of ice cores recovered from Law Dome on the … coast of Wilkes Land, East Antarctica. These samples include ice dating from the Last Glacial Maximum … (LGM), the Last Deglaciation…
We used a snow pit record in conjunction with detailed snow accumulation data and … oxygen isotope records to examine atmospheric transport and deposition effects on 10Be at … Law Dome, Antarctica.
The degree to which Southern Hemisphere climatic changes during the end of the last … glacial period and early Holocene (30-8 ka) were influenced or initiated by events occurring in the high … latitudes of the Northern Hemisphere is a complex issue.
Antarctic snowfall exhibits substantial variability over a range of time scales, with consequent … impacts on global sea level and the mass balance of the ice sheets. To assess how snowfall has … affected the thickness of the ice sheets in Antarctica and to provide an extended perspective…
Environmental Earth Science … Pollution history
This paper is an extension of the paper by King et al. (2000), where two techniques were described to … process GPS data collected on a floating Antarctic ice shelf. King et al. (2000)…
Methanesulphonic acid (MSA) measured along ice cores was largely used as a marker of … past marine biogenic activity because of it is formed by atmospheric oxidation of … dimethylsulphyde (DMS), emitted by metabolic processes of marine biota.
The efforts of Patterson and co-workers (Murozumi et al., 1969) to accurately measure Pb … concentrations in Greenland and Antarctic snow and ice produced the first reliable … determination of Pb pollution of the Earth’s polar ice sheets. Since then…
In recent times there has been increasing interest in Sr as an isotopic tracer in environmental … studies. There is the potential to characterise dust inputs at a certain site by transport of … material from source areas if the isotopic compositions of the site and source areas are … known.
Antarctic ice is an archive of evidence of climatic conditions and natural phenomena in the … Southern Hemisphere that extends approximately one million years into the past. We can … sense changes through the concentration of atmospheric gases, stable isotope ratios, terrestrial dust levels…
Conventionally the source of sea salt in the Antarctica was considered to be the ocean … surface. In simple terms, sea salt is ejected into the atmosphere as sea spray droplets, mixed … in the atmosphere, and transported to Antarctica via storm activity. Recently, however…
The microparticle record from the Dome Summit South ice core, Law Dome, East Antarctica … is investigated using a Coulter Multisizer to provide concentration and size distribution at … selected depths. This core site has an unusually high accumulation rate (640 kg m2/a) during … the Late Holocene…
Snow accumulation rates at the summit of Law Dome are examined on three different … timescales. For the full record covering the last ~ 90,000 years accumulation rate is … determined as an output of the model used for ice core dating.
Glaciological and over snow programs were the only possible avenues available for … determining dh/dt and mass balance in the 1960s. Law Dome in East Antarctica was … extensively traversed with several methodologies including gravity during the 1960s and into … the 1970s.
The phase lag between atmospheric composition (air bubbles) and temperature (water isotopes) can be quantified from ice cores provided that the age difference between entrapped air and the surrounding air can be correctly estimated. This difference depends on the lock-in depth (LID)…
ABSTRACT. We present highly resolved, annually dated, calibrated proxies for atmospheric circulation … from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition), Siple … Dome, Law Dome)…
Until recently, the IGS network of global tracking sites was predominently populated y Rogue/Turborogue GPS receivers. Firmware used in these receivers was found to perform poorly during periods of high ionospheric disturbances and, during 1999/2000…
