The Gulf of Thailand: Geography, Ecology, Economy, and Tourism
Introduction
The Gulf of Thailand (also known as the Siam Gulf) is a warm, shallow gulf in the western part of the South China Sea. It borders the southeastern coast of Thailand, as well as parts of Cambodia, Vietnam, and Malaysia. The gulf plays a crucial role in the region’s economy and ecology and is a popular tourist destination due to its scenic islands, white sandy beaches, and rich marine life.
1. Geographic Location and Characteristics
The Gulf of Thailand is located in Southeast Asia and is bordered by several countries:
- West and northwest – the coastline of Thailand
- Northeast – southern Cambodia
- East – southern Vietnam
- South – the Malay Peninsula and the South China Sea
The gulf connects to the South China Sea through the Malacca Strait and Vietnam's southern waters.
Main Characteristics
- Area: ~320,000 km²
- Average Depth: 45 m
- Maximum Depth: ~80 m
- Water Temperature: Between +26°C and +30°C
- Salinity: ~32–34 parts per thousand
The gulf is relatively shallow, as it was formed by the flooding of lowland areas during the last Ice Age.
2. Ecology and Marine Flora & Fauna
The Gulf of Thailand has a unique ecosystem, but it faces environmental threats related to pollution, overfishing, and climate change.
Flora and Fauna

- Turtles: Green sea turtles and hawksbill turtles nest on some of the gulf’s islands.
Environmental Threats
- Oil and plastic pollution. Major pollution sources include shipping, tourism, and fishing industries.
- Overfishing. Intensive commercial fishing has led to a decline in certain fish populations.
