Journal Article
Fox, L. R., Wade, B. S., Holbourn, A., Leng, M. J., & Bhatia, R. (2021). Temperature Gradients Across the Pacific Ocean During the Middle Miocene. Paleoceanography and Paleoclimatology, 36(6), 1-16. https://doi.org/10.1029/2020PA003924

Sea surface temperatures (SSTs) of the tropical Pacific Ocean exert powerful controls on regional and global climates. Previous studies have suggested that during warm climate phases, the east-west temperature gradient collapsed. To date, there has b...
