What is a deep-water bay?

A deep-water bay is a valuable asset for countries with long coastlines. Investing in the development of deep-sea ports not only enhances the competitiveness of the economy but also contributes to the protection of maritime sovereignty.

Additionally, according to the provisions of Article 10 of the UNITED NATIONS CONVENTION ON THE LAW OF THE SEA 1982:

Bays

1. This article relates only to bays the coasts of which belong to a single State.

2. For the purposes of this Convention, a bay is a well-marked indentation whose penetration is in such proportion to the width of its mouth as to contain land-locked waters and constitute more than a mere curvature of the coast. An indentation shall not, however, be regarded as a bay unless its area is as large as, or larger than, that of the semi-circle whose diameter is a line drawn across the mouth of that indentation.

3. For the purpose of measurement, the area of an indentation is that lying between the low-water mark around the shore of the indentation and a line joining the low-water mark of its natural entrance points. Where, because of the presence of islands, an indentation has more than one mouth, the semi-circle shall be drawn on a line as long as the sum total of the lengths of the lines across the different mouths. Islands within an indentation shall be included as if they were part of the water area of the indentation.

4. If the distance between the low-water marks of the natural entrance points of a bay does not exceed 24 nautical miles, a closing line may be drawn between these two low-water marks, and the waters enclosed thereby shall be considered as internal waters.

5. Where the distance between the low-water marks of the natural entrance points of a bay exceeds 24 nautical miles, a straight baseline of 24 nautical miles shall be drawn within the bay in such a manner as to enclose the maximum area of water that is possible with a line of that length.

6. The foregoing provisions do not apply to so-called "historic" bays, or in any case where the system of straight baselines provided for in article 7 is applied.

Thus, a deep-water bay is one with significant depth, sufficient to allow large-sized, heavy-loaded ships (such as ultra-large container ships) to enter, exit, and anchor safely.

This depth is typically measured from sea level to the bottom of the bay, depending on the type of ship intended to be serviced. Modern international ports often require a minimum depth of 14 meters or more to accommodate ultra-large container ships.

What is the grade at which students will study bays in Vietnamese seawaters in the History and Geography curriculum?

Under the General education program for History and Geography at the lower secondary level issued together with Circular 32/2018/TT-BGDDT, the content and requirements for the 8th-grade History and Geography curriculum are as follows:

- Geographical position and natural characteristics of Vietnamese seawaters and islands

+ Identify on a map the scope of the East Sea, the countries, and territories sharing the East Sea with Vietnam.

+ Describe the natural characteristics of Vietnamese seawaters and islands.

- Vietnamese maritime zones in the East Sea

+ Identify on a map the base points, and demarcation lines of the Gulf of Tonkin between Vietnam and China; explain the concepts of internal waters, territorial sea, contiguous zone, exclusive economic zone, and continental shelf of Vietnam (according to Vietnam's Maritime Law).

- Environment and resources of Vietnamese seawaters and islands

+ State the characteristics of the maritime island environment and the issue of protecting Vietnam's maritime island environment.

+ Describe the marine resources and continental shelf of Vietnam.

Thus, bays in Vietnamese seawaters will be taught in the 8th-grade History and Geography curriculum.

How many lessons does the 8th-grade History and Geography curriculum in Vietnam have?

According to the General education program for History and Geography at the lower secondary level issued together with Circular 32/2018/TT-BGDDT, the curriculum includes 105 lessons per grade per school year. The percentage of lessons dedicated to each content is in the table below:

Thus, the 8th-grade History and Geography curriculum includes 105 lessons per school year, with 41 lessons for History, 41 lessons for Geography, 8 lessons for common themes, and 10 lessons for periodic assessment.
