Increased biological productivity and export production in the glacial Southern Ocean
Article Abstract:
The increase in export production in the Southern Ocean contributed to low levels of carbon dioxide and high levels of iron in the glacial atmosphere. The winds from Patagonian deserts transported iron to the Southern Ocean. The observations compare well with the fact that the iron depletion in the Ocean in the glacial periods was reduced by iron-rich winds. The fluxes of biogenic detritus out of surface waters were high in the glacial periods.

Persistence of full glacial conditions in the central Pacific until 15,000 years ago
Article Abstract:
The reconstruction of atmospheric temperatures in the central Pacific during the last deglaciation on the basis of cosmogenic [super 3]He ages of moraines and numerical modeling of the ice cap on Mauna Kea volcano, Hawaii, are described. The persistence of full glacial conditions until 15,000 years ago is found to be consistent with the relatively late and abrupt transition to warmer temperatures in Greenland.

Sea-level fluctuations during the last glacial cycle
Article Abstract:
The characteristics of the last glacial cycles are discussed. The changes in sea-level and the climatic changes in relation to the glacial cycle are mentioned and oxygen isotope records from Red Sea sediment cores to reconstruct the history of water residence times in the Red Sea are analyzed.
