- Determine the status of the environmental factors at seven coastal stations are Nha Trang, Phan Thiet, Ganh Rai, Đinh An, Song Doc, Rach Gia, Ha Tien, and one open sea station (Phu Quy) in April.
- Preliminary assessment of the environmental quality of the areas from 2016 to 2020.

Theorerical results: To produce the accurate, synchronous, and continuous data of the environmental factors at the fixed stations. These data can serve in the purposes as study, teaching, and warning to the environment.
Applied results: the collected data were the parameters in annual national environmental state report
- The analytical results in 2020 showed:
In water
Environmental quality at most stations were at the "low environmental pollution" (RQ <1) in all surveys. However, Dinh An station in May had RQ = 1.07, and Ha Tien in August had RQ = 1.23, at the " average environmental pollution". The factors that make RQ index increase at the stations were Coliform, Fe and Nitrate. Nha Trang has the stable and best environmental quality with RQ from 0.11 to 0.12 in surveys. Phan Thiet, Ganh Rai and Song Doc stations also had good environmental quality with the RQ values always <0.5. Dinh An and Ha Tien stations had unstable environmental quality among surveys, with RQ values ranging from 0.43 to 1.07 in Dinh An, and from 0.26 to 1.23 in Ha Tien. Phu Quy offshore station has good environment with RQ = 0.28, at the “low environmental pollution”.
In sediment
Phan Thiet station was at the level of lowest potential of adverse biological effect (SQG-Q < 0,1). The remaining stations were at medium potential of adverse biological effect (0.1 < SQG-Q < 1).

For the Phytoplankton: A total of 391 phytoplankton species/subspecies were recorded, of which diatoms accounted for 59.33%. Other Ochrophyta, Cerozoa, Charophyta, Chrysophyceae, and Haptophyta accounted for <3% of the recorded species. 33 species of potentially harmful phytoplankton belonging to 6 phyla were recorded, of which the dinoflagellates had the most species (24 taxa), and the least was Haptophyta (1 taxa). Pseudo-nitzschia spp. appeared mostly in stations, and Nha Trang had the highest cell density in all 4 sampling times. In which, in June, the density of this species reached 426,667 cells/L (at the surface layer, low tidal time), nearly reached the warning threshold of closing the farming area to control (Todd, 2003).
For the Zooplankton: A total of 197 zooplankton species were recorded, of which group Copepoda accounted for more than 50%. The highest average density of zooplankton was recorded at Dinh An station (113,593 individuals/m3 in March, and 133,333 individuals/m3 in May). Nha Trang station had the lowest average density, reaching 2,016 individuals/m3 in August.
For the Benthos: A total of 133 benthos species were recorded, of which class Polychaeta accounted for the highest proportion, and Echinodermata accounted for the lowest. Ha Tien station has the highest average density, reaching 4,850 individuals/m2, however the largest biomass was in Ganh Rai station, reaching 429.92g/m2 in March. Song Doc station not only has the lowest density but also the lowest biomass, with a density of 33 individuals/m2 and biomass of 0.18g/m2 in October.
There is no clear trend for variation of chemical and ecological factors, phytoplankton, zooplankton, and benthos at the stations during the 2016 – 2020.

Extending the data at the fixed stations to the time

- Four reports and data files (of 4 surveys in March, May-July, August, and October, 2020) containing information of factors about marine meteorology, hydrology, dynamics, chemistry, and biology (phytoplankton, zooplankton and benthos) at seven coastal stations and one open sea station
- One summarization report containing the comments of dada, warming and explanations about the over limit value of the environmental fators

It is necessary to increase the number of monitoring stations anually following in the development of coastal industrial zones, and export proccessing zones.
