Plutonium fallout reconstructed from an Antarctic Plateau snowpack using inductively coupled plasma sector field mass spectrometry
2019, Science of the Total EnvironmentCitation Excerpt :Previous studies used radioactivity counting methods (Cutter et al., 1979; Koide et al., 1979) or accelerated mass spectrometry (Koide et al., 1985), both of which required large sample amounts (10–100 kg), complicated pretreatments (e.g., Pu purification), and time-consuming instrumental analyses. Similar to using the maximum fallout of tritium (3H) as an age indicator of 1966 (Jouzel et al., 1979; Kamiyama et al., 1989; Hoshina et al., 2014), those studies proposed the chronological potential of Pu for dating Antarctic snow (Koide et al., 1985). However, Pu has rarely been used chronologically because of the difficulty of measuring low levels of Pu.
Spatial analysis of the atmospheric helium isotopic composition: Geochemical and environmental implications
2018, Geochimica et Cosmochimica ActaCitation Excerpt :Antarctica is a region of high pressure, where subsiding air from the stratosphere can drive particles rich in cosmogenic nuclides (3H → 3He, 10Be) and ozone into the troposphere (Jouzel et al., 1979). The stratospheric intrusions of air masses with high tritium content have a maximum effect on the local air tritium concentration especially during the austral winter (Jouzel et al., 1979; Fourré et al., 2006), which was during our sampling period. According to Stohl and Sodermann (2010), the probability for near-surface air to originate from the stratosphere on a time scale of 10 days is one order of magnitude higher near the South Pole than near the North Pole.
The global distribution of natural tritium in precipitation simulated with an Atmospheric General Circulation Model and comparison with observations
2015, Earth and Planetary Science LettersA snow/firn four-century record of polycyclic aromatic hydrocarbons (PAHs) and polychlorobiphenyls (PCBs) at Talos Dome (Antarctica)
2012, Microchemical JournalCitation Excerpt :Volcanic eruptions emit large amounts of ash and gas into the atmosphere, including SO2 and a wide variety of organic compounds [54,55]. The removal of gas, vapors, dust and aerosol from the atmosphere, for instance by snowflakes, and the consequent deposition on the ice sheet increase the sulphate content, thus produces useful horizons (i.e. volcanic signals) for dating ice cores and studying past chemical changes of the atmosphere [52–56]. A dating error may reach ± 5 years at points that are a long way from dated reference horizons [52].
Tritium profiles in snowpacks
2010, Journal of Environmental RadioactivityCitation Excerpt :For dose assessment, the processes contributing to the time evolution of the contaminated snowpack and the fraction of deposition still present in the spring are of relevance, as snow-melt releases tritium to the land surface where it can potentially enter groundwater, soil water and crops. The data pertaining to bomb fallout (Jouzel et al., 1979) are of limited usefulness in studying these processes, due to the quasi-continuous character of the source and the exotic site (Antarctica). Recently, theoretical work on pollutant transport in snow was published by Bales (1991) which emphasises pollutant diffusion, and includes the role of chemical transformation, the mobile air phase and the immobile water and ice phases.
