PP33B:
Climate, Carbon Cycle, and Biogeochemical Reconstructions from the Eastern Tropical Pacific II Posters

Submit an Abstract to this Session



Session ID#: 22452

Session Description:
The Eastern Tropical Pacific is a key paleoceanographic region given its role in global climate, the carbon cycle, and biogeochemical cycling. As such, the area has served as a target location for many sediment coring and drilling expeditions over the years. With advances in analytical techniques and modeling studies, new records from this region continue to be produced. This session aims to bring together the latest research on the Eastern Tropical Pacific across all time scales, utilizing any proxies or archives, including modeling studies. In addition, we welcome studies integrating data from across the entire tropical pacific, including the Central and Western Tropical Pacific.
