Year-round aerosol samples collected in the boundary layer at coastal Antarctic sites (Dumont D’Urville, Neumayer, and Halley) indicate a seasonal cycle of ammonium concentrations with a minimum in winter (April–September). […]
Multiple-year time series of the weight ratio R of methane sulfonic acid (MSA) to non-sea-salt sulfate (nss SO4) in aerosols collected at three coastal Antarctic stations Neumayer (70°39′S, 8°15′W), Halley […]
There is a global need to develop strategic frameworks for assessing uncertainty in ecosystem dynamics models. Such models have been used within CCAMLR to evaluate options for managing the Antarctic […]
Strontium isotope stratigraphy was used to date five discrete horizons within CRP- 1. Early and late Quaternary (0 87- 1 3 Ma and 0-0 67 Ma respectively) age sediments overlie […]
The simple tectonic history of the South Sandwich island arc, a classic intra-oceanic arc lying in the South Atlantic Ocean, provided excellent opportunities for the Sandwich Lithospheric and Crustal Experiment […]
Long term air and snowfall chemistry measurements have been performed at the three coastal Antarctic stations Dumont d’Urville (66°40′S, 140°1′E), Neumayer (70°39′S, 8°15′W), and Halley (75°35′S, 26°19′W). The results have […]
The temperature of the Southern Ocean has undergone an overall reduction from about 20 °C to −1.8 °C over the last 55–60 million years. To date, the Southern Ocean is […]
We use snow surface temperatures obtained from thermal infrared (TIR) satellite imagery, together with radiosonde profiles of free-air temperature and high-resolution topographic data to study the thermal structure of the […]
Temperature records from stations on the west coast of the Antarctic Peninsula show a very high level of interannual variability and, over the last 50 years, larger warming trends than […]
Levels of persistent organic pollutants (POPs), such as polychlorinated biphenyls and pesticides have been determined in ambient air at Signy Island, Antarctica, over a period of 17 weeks. Mean concentrations […]
Macrofossil content from the Miocene part of CRP-1 core, Cape Roberts (Victoria Land Basin) is scant and mostly limited to a few pectinid bivalves and serpulid polychaetes. Selective diagenesis has […]
