Study results show that in recent years, ocean observations of Vietnam have been equipped with a series of modern measured and analyzed instruments, especially at related offices of the Vietnam Academy of Science and Technology (VAST) and Ministry of Natural Resources and Environment (MONRE). The remarkable progress was to carry out the UAV (Unmanned Aerial Vehicle) program to observe oceanographic conditions in nearshore region by VAST from 2013. Earlier, from 2009 the MONRE carried out the program to establish a network of stations to observe waves and current characteristics in nearshore region by high frequency radar technology. However, the current status of ocean observations and services in Vietnam still has shortcomings in both manpower and equipment and the observations are mostly focused in the nearshore region. Services on oceanographic data are still less professional and public. For sustainable development of ocean observations and service, it is necessary to promote international cooperation projects on oceanography especially in the frame-work of IOC/WESTPAC cooperation.

INTRODUCTION Vietnam is a marine country located in the West of the East Sea and has 3,260 km coastline consisting of bays, harbours and more than 3,000 islands with various scales. Vietnam’s sea is considered as an important gateway for .
