Cenozoic climate and ocean chemistry changes are linked to the                  evolution of deep-water circulation patterns.  A project to                     reconstruct Cenozoic deep-water circulation changes will use                    benthic foraminiferal >.>13C comparisons, supplemented by ongoing               faunal (benthic foraminiferal) and sedimentological studies                     (CaCO3, opal, organic carbon accumulations).  An integrated                     statigraphic framework for synoptic interbasinal and                            bathymetric (vertical) >.>13C comparisons will be constructed.                                                                                                  Detailed interbasinal >.>13C reconstructions of the Oligocene to                Pliocene oceans will delineate various water-type end members                   (Northern Component, Southern Component, Indian Ocean Water,                    Pacific Deep Water).  Vertical >.>13C gradients will be                         reconstructed in several regions including the North Atlantic                   and Southern Ocean.  These reconstructions will allow                           evaluation of the role of these critical bottom-water source                    regions upon the development of long period (106yr) deep-water                  circulation.  The importance of shorter-period (104-105yr)                      changes across two major climatic transitions (ca. 14-12.5 Ma                   and 3-2 Ma) will be used to determine if climatic forcing on                    this bandwidth was linked to deep-water variations as in the                    Quaternary.                                                                     %%%                                                                             This study will involve the use of oxygen and carbon isotopes                   of foraminifera from sedimentary cores.  The history of deep                    circulation will be inferred for the last 40 million years in                   order to examine the effects of climate on paleocirculation.                    The results will provide the opportunity to test models of the                  interaction of paleoclimate, paleoceanography, and plate                        tectonic reconstructions on the evolution of the modern ocean.
