Coastal waters refer to the areas of the ocean that are near the shore, typically extending from the high tide line to the outer edge of the continental shelf. These waters are influenced by both marine and terrestrial environments, making them rich in nutrients and biodiversity. They support various ecosystems, including estuaries, mangroves, and coral reefs. These regions are vital for human activities, providing resources such as fishing grounds and recreation. Coastal waters also play a crucial role in regulating climate and protecting coastlines from erosion. Their health is essential for both wildlife and communities that depend on them for livelihood and enjoyment.
