Stable isotope record, calcium carbonate conentrations, and sea surface tempe...
We analyze five high-resolution time series spanning the last 1.65 m.y.: benthic foraminiferal delta18O and delta13O, percent CaCO3, and estimated sea surface temperature (SST)... -
Glacial North Atlantic: Sea surface conditions reconstructed by GLAMAP 2000, ...
The response of the tropical ocean to global climate change and the extent of sea ice in the glacial nordic seas belong to the great controversies in paleoclimatology. Our new... -
Foraminiferal faunal estimates of paleotemperature: Circumventing the no-anal...
The sensitivity of the tropics to climate change, particularly the amplitude of glacial-to-interglacial changes in sea surface temperature (SST), is one of the great... -
Stable carbon and oxygen isotope ratios of benthic and planktic foraminifera ...
Benthonic foraminifera in late Pleistocene deep-sea cores show significant variation in delta 13C with depth in sediment. This, and the report by Sommer et al., (in prep) of... -
Stable carbon and oxygen isotope ratios of planktonic foraminifera from the e...
Carbon isotopic records of nutrient-depleted surface water place constraints on the past fertility of the oceans and on past atmospheric pCO2 levels. The best records of... -
Age models, accumulation rates, and grain size distributions of sediment core...
The terrigenous sediment proportion of the deep sea sediments from off Northwest Africa has been studied in order to distinguish between the aeolian and the fluvial sediment... -
Determination of Uranium, Thorium, and Ionium in sediment cores of the Caribb...
A rapid procedure for Io (Th230) dating of sediments with accumulation rates in the range of several cm/1000 years is described. Studying of large sample populations with very...
