Ice within marine basins of East Antarctica, and their outlets, represent the ultimate limit on sea level change. The region of East Antarctica between the Ross Sea and Wilkes Land hosts a number of major basin, but has been poorly understood. Long range aerogeophysics from US…
Studies of atmospheric composition in the Southern Ocean and Antarctic region continue to … reveal new findings which have a wide relevance. This presentation will show and interpret … records of the major greenhouse and related trace species from a network of measurement … sites across the region…
New measurements of atmospheric greenhouse gas … concentrations in ice from Law Dome, Antarctica reproduce … published Law Dome CO2 and CH4 records, extend them … back to 2000 years BP, and include N2O. They have very … high air age resolution, data density and measurement … precision.
Measurements of atmospheric trace gas composition from times before reliable direct observations began in the late 20th century come from air enclosed in polar ice and firn. This presentation will review the evidence for changes in atmospheric CO2…
The event that occurred approximately 8200 years ago is the largest excursion in climate since the beginning of the Holocene. In this event we observe the climatic response to a perturbation which provides a probe with which to investigate the stability of interglacial climate.
We report a 2000-year Antarctic ice-core record of stable carbon isotope measurements in atmospheric methane (ä13CH4). Large ä13CH4 variations indicate that the methane budget varied unexpectedly during the late preindustrial Holocene (circa 0 to 1700 A.D.). During the first thousand years…
