Halogen species record Antarctic sea ice extent over glacial – interglacial periods
Sea ice is an integral part of the earth’s climate system because it affects planetary albedo, sea-surface salinity, and the atmosphere–ocean exchange of reactive gases and aerosols. Bromine and iodine chemistry is active at polar sea ice margins with the occurrence of bromine explosions and the biological production of organoiodine from sea ice algae. Satellite measurements demonstrate that co...
متن کاملStrong coupling of Asian Monsoon and Antarctic climates on sub-orbital timescales
There is increasing evidence that millennial-scale climate variability played an active role on orbital-scale climate changes, but the mechanism for this remains unclear. A (230)Th-dated stalagmite δ(18)O record between 88 and 22 thousand years (ka) ago from Yongxing Cave in central China characterizes changes in Asian monsoon (AM) strength. After removing the 65°N insolation signal from our re...
متن کاملSouthern Ocean Overturning Role in Modulating High Southern Latitude Climate and Atmospheric CO2 on Millennial Timescales
During the last glacial period and particularly Marine Isotope Stage 3, North Atlantic Deep Water (NADW) formation weakened significantly on a millennial timescale leading to Greenland stadials (Kissel et al. 2008). Ice core records reveal that each Greenland stadial is associated with a warming over Antarctica, so-called Antarctic Isotope Maximum (AIM) (EPICA and Community Members 2006). Recen...
متن کاملAntarctic Sea Ice History, Late Quaternary
Sea ice results from the freezing of surface sea water. In the Southern Ocean, sea ice surrounds the Antarctic continent and it today covers 20 × 10 km in winter and only 4 × 10 km in summer (Gloersen et al., 1992). This pronounced seasonal cycle strongly affects the climate of the Southern Hemisphere through its impacts on the energy and gas budget, on the atmospheric circulation, on the hydro...
متن کاملAn emerging technique: multi-ice-core multi-parameter correlations with Antarctic sea-ice extent
Using results stemming from the International Trans-Antarctic Scientific Expedition (ITASE) ice-core array plus data from ice cores from the South Pole and Siple Dome we investigate the use of sodium (Na), non-sea-salt sulfate (nssSO4 ) and methylsulfonate (MS) as proxies for Antarctic sea-ice extent (SIE). Maximum and mean annual chemistry concentrations for these three species correlate signi...
