Application of a New Method for Isotopic Analysis of Diatom Microfossil-bound Nitrogen
Entry ID: NSF-ANT04-53680

Abstract: The Southern Ocean may play a central role in causing ice ages and general global climate change. This work will reveal key characteristics of the glacial ocean, and may explain the cause of glacial/interglacial cycles by measuring the abundances of certain isotopes of nitrogen found in fossil diatoms from Antarctic marine sediments. Diatom-bound N is a potentially important recorder of nutrient ... View entire text
