 P-A-L-E-O-C-E-A-N-O-G-R-A-P-H-E, Paleocyanography is the study of the history of the oceans in the geologic past with regard to circulation, chemistry, biology, geology and patterns of sedimentation and biological productivity. Paleocyanographic studies using environment models and different proxies enable the scientific community to assess the role of the oceanic processes in the global climate by the reconstruction of past climate at various intervals. Paleocyanographic research is also intimately tied to paleoclimatology.
