Vietnam is a coastal nation with a coastline stretching over 3,260km and a vast exclusive economic zone, playing a particularly important role in socio-economic development and ensuring national security and defense.
However, current marine environmental monitoring still relies mainly on manual sampling methods, which are infrequent, have a large time lag, make it difficult to detect sudden pollution incidents in a timely manner, and do not meet the requirements of modern management.
Based on that practical need, the Ministry of Science and Technology approved the national-level science and technology task "Research on optical sensor technology and design and development of an automatic, remote monitoring system for application in monitoring the marine environment of Vietnam" (code DTĐL.CN-92/21) according to Decision No. 476/QD-BKHCN dated March 15, 2021.
The project, chaired by Dr. Le Duy Tien, is being implemented by the International School of Vietnam National University, Hanoi, during the period 2021-2025. Information regarding the implementing agency, location, and scientific titles remains unchanged and is not affected by any administrative unit restructuring.
After research, the team successfully developed an automated marine environmental monitoring system capable of continuously measuring important parameters such as temperature, salinity, dissolved oxygen, pH, turbidity, and pressure. Simultaneously, the team developed and tested a new optical sensor for measuring NaCl, along with sensor designs that are highly sensitive, have a wide measurement range, and can withstand harsh marine environmental conditions.
Another notable achievement is the multi-hop wireless remote data transmission system, designed to suit the marine environmental conditions of Vietnam, ensuring continuous and stable data collection and transmission. Simultaneously, a synchronized database and software system for managing and processing observational data has been developed, along with a comprehensive set of operational instructions.
At the end-of-year 2025 evaluation and acceptance meeting of the research project, the council members highly appreciated the scientific quality, progress, and applicability of the products. The council unanimously approved the project as "Satisfactory" and requested the research team to complete the documentation for the Ministry of Science and Technology to recognize the results.
This result demonstrates the technological mastery of Vietnamese scientists, creating an important foundation for the development of modern marine monitoring systems, serving resource management and sustainable marine environmental protection.
