Insoluble nanoparticles in the form of aerosols have significant effects on climate and biogeochemical cycles. Records of these aerosols are essential for understanding paleoclimate forcing and future climate change.
Insoluble nanoparticles, in the form of aerosols, have significant affects on climate and biogeochemical cycles. Records of these aerosols are essential for understanding paleoclimate forcing and future climate change. While a large body of research exists with respect to mineral dust particles…
A compilation of sea salt data from East Antarctic ice cores are used to quantify the contribution of open ocean and sea ice to the sea salt budget. The ice cores used in this study are from Law Dome, Totten Glacier, Wilkes Land and Wilhelm II Land.
Coastal Antarctic sea salt aerosols are partitioned into two main sources, namely ocean sea spray and surface sea ice. The sea spray source is related to windiness over the surface ocean and the action of bubbles bursting.
Knowledge of environmental variability and change during the … Medieval Climate Anomaly (MCA ; ~800 to 1300 - 1400 AD) in the Southern Hemisphere has been characterized by a La Nina-like mean climate state in the Pacific Basin…
It has recently been shown that sea ice (via frost flowers) is an important source of sea … salt to coastal Antarctica. This has been used to suggest that the sea salt record from … ice cores may reflect a proxy for sea ice extent around Antarctica. In this study…
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…
From its original formulation in 1990 the International Trans-Antarctic Scientific Expedition … (ITASE) has had as its primary aim the collection and interpretation of a continent-wide array of … environmental parameters assembled through the coordinated efforts of scientists from several nations.
The Southern Hemisphere westerlies in the southwest Pacific are known to have waxed and waned numerous times during the last … two glacial cycles, though even semi-continuous histories of the westerlies extend back no more than about 20,000 years.
