Antarctic 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 کاملReconciliation of late Quaternary sea levels derived from coral terraces at Huon Peninsula with deep sea oxygen isotope records
A major discrepancy between the Late Quatemary sea level changes derived from raised coral reef terraces at the Huon Peninsula in Papua New Guinea and from oxygen isotopes in deep sea cores is resolved. The two methods agree closely from 120 ka to 80 ka and from 20 ka to 0 ka (ka = 1000 yr before present), but between 70 and 30 ka the isotopic sea levels are 20-40 m lower than the Huon Peninsul...
متن کاملLate Quaternary sea-level and tectonic changes in northeast Fiji
The islands of northeast Fiji studied are all the emergent parts of the northern end of the Lau^Colville Ridge, a remnant island arc which has been rising for most of the Quaternary. Within the study area, investigations of coastal landforms (primarily emerged notches and shore platforms) and emerged coral reefs allow rates of tectonic movements to be calculated. The Vanuabalavu Island group is...
