摘要：The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) provides users of its data with comprehensive search services that enable users to find data in JAMSTEC's various data dissemination sites. These are the "JAMSTEC Data Search Portal" that helps users to search for observational data on a map and the "JAMSTEC Data Catalog" that enables users to find data sites by selecting science keywords. The "Data Search Portal" and the "Data Catalog" have been developed and operated as dedicated metadata publication and search services that collaborate with data sites in JAMSTEC.
