In the maritime context, sea refers to the vast body of salt water that covers the majority of the Earth's surface. It includes the five major oceans - the Atlantic, Indian, Southern, Arctic, and Pacific - as well as smaller bodies of water such as the Mediterranean Sea, the Red Sea, and the Gulf of Mexico.
The sea is an important transportation route for shipping and maritime trade, and it is also an important resource for fishing, oil and gas exploration, and recreation.
Examples of activities in the maritime context include:
- Commercial shipping, where cargo ships transport goods and raw materials across the seas
- Fishing, where boats and ships are used to catch fish and other sea life for food and commercial purposes
- Oil and gas exploration, where companies use ships and drilling platforms to explore and extract oil and gas from the sea bed
- Recreational activities such as cruising, sailing, and scuba diving
- Offshore wind and wave energy generation
- Marine scientific research
- Coastal and port management.
It's worth to mention that the sea is also a source of concern as it can be affected by pollution, climate change, overfishing and other human activities. Therefore, there are regulations and organizations in place to protect the sea and its resources, and ensure safe and sustainable use of the maritime environment.
