Summary: The stratigraphic phase of the paleoceanographic Indian Ocean synthesis project (PALIOS) has established a rigorous framework for paleoceanographic synthesis of both DSDP and ODP results. Most importantly, the authors have completed an integrated stratigraphic framework that allows correlation between the low and high latitudes and takes account of the existence of diachronous fossil datums. A simple spreadsheet routine has been developed to calculate the depth/age curve for each site which in turn provides the basis for assigning an age to each sample/measurement point. This has become the basis for a number of target projects that will culminate in time series palinspastic maps showing accumulation rates and paleobathymetry. Preliminary results of two of the target projects suggest that hiatuses linked to bottom water circulation could be more regionalized than previously thought. Whilst volcanogenic sediment input appears most closely linked to the evolution of "hotspots", the resulting distributions are controlled by dispersal mechanisms that include paleowinds and surface water mass circulation.
