This $372,515 Project Grant awarded by the National Science Foundation (NSF) Geosciences program (CFDA 47.050) supports research to document variations in the influence of the Southern Hemisphere on the Western Pacific Warm Pool thermocline over the past 1.5 million years. The principal investigators at Columbia University will analyze geochemical data from deep-sea sediment cores to determine the timing and patterns of subsurface warming in the Western Pacific Warm Pool relative to surface ocean conditions during glacial-interglacial transitions. The goal is to understand whether this subsurface warming may have been a triggering event for past global warming periods and to assess its implications for current and future climate change. The research project is expected to be completed by April 2026.
