Welcome to visit the Website of National Marine Data and Information Service (NMDIS).

　　The National Marine Data and Information Service (NMDIS) is a national facility under the State Oceanic Administration (SOA) of China responsible for looking after and distributing data and information cocncerning the marine environment. As a National Oceanographic Data Center, NMDIS maintains and develops the national marine database. This is a collection of marine data sets originating mainly from China marine observation establishments. NMDIS is not only providing marine data and information services, but also providing technical support for national marine economic development, sea area management, marine environmental protection, and marine research community. 

　　NMDIS manages tidal data recorded from tidal stations along the Chinese coast. The tide and tidal current analysis and prediction are one of the major task of the NMDIS. The tide tables for China Seas as well as world oceans are compiled and published yearly by NMDIS.

　　As a national coordinator, NMDIS is actively participating the activities of International Oceanographic Data and Information System (IODE) and many other international marine data and information manageement activities. NMDIS hosts the World Data Center for Oceanography ( Tianjin, China), China Argo Data Center, China Delayed Mode Database for NEAR-GOOS. NMDIS manages the ODAS Metadata Center for JCOMM.

　　We are eager to cooperate with relevant institutions both nationally and internationally to improve our service and collections.
