International scientific ocean drilling dates back to the “Project Mohole” in the 1960s, and includes the later Deep Sea Drilling Project, Ocean Drilling Program, Integrated Ocean Drilling Program and International Ocean Discovery Program. Through over 300 ocean drilling tasks，a large amount of precious data have been obtained from the seafloor and now stored in multiple databases. Those data record the characteristics of the core samples in various aspects such as physical, chemical, lithological, micropaleontological, etc., as well as logging information. All the information has been acquired either from shipboard bservations and measurements or after-cruise experimental analysis. In addition to being stored in IODP databases, these data have been published in relevant journals of ocean drilling, and some were deposited in other professional databases. These data are difficult to combine all together because different data types among the databases and in each database, the data search routine is too simple for advanced use. To set up a comprehensive data platform to store and manage heterogeneous data from ocean drilling projects and integrate various services and functions processing the data for more broad use, will be a task for eological community in the future.
