Professor Emeritus

Research Interests

Study of Late Cenozoic history of the ocean-climate systems as recorded in deep-sea sediments so as to better understand the nature of global climate change, marine stratigraphy and sedimentation, numerical and statistical techniques as applied to geological problems.

Current Research

Detailed analysis of Late Pleistocene time series of oceanographic variability in the Pacific Ocean with emphasis on the eastern equatorial Pacific and northern California Current region.
