Seas can be partly enclosed by land or completely enclosed by land. Some seas are part of an ocean like the Tasman Sea in the Pacific Ocean. Some seas are called bays, for example, the Bay of Bengal, and some are called gulfs such as the Gulf of Mexico. Some are lakes, like the Caspian Sea. When a sea is a part of an ocean, the ecosystems are similar, and the conservation issues faced are the same.

This entry will help you find information about the sea, its protection and its importance to Māori.

Well known seas

Here is a list of some seas and where they are located. Try finding them on a map of the world.

Arabian Sea: located northwest of the Indian Ocean. India, Pakistan, Iran, Oman and Somalia are some of the countries that surround it.

Baltic Sea: is part of the North Atlantic Ocean in northern Europe. Finland, Latvia, Lithuania, Poland, Russia, Germany and Denmark are some of the countries that border it.

Bay of Bengal: lies to the north of the Indian Ocean. It is bordered by Sri Lanka, India, Bangladesh, Myanmar and Malaysia.

Caribbean Sea: is part of the North Atlantic Ocean near the Gulf of Mexico. Cuba, Puerto Rico, Guatemala, Nicaragua and Columbia are a few countries that surround it.

Caspian Sea: is actually a lake called an inland sea. Located in Central Asia, it is bordered by Kazakhstan, Turkmenistan, Iran, Azerbaijan, and Russia.

Coral Sea: lies in the South Pacific Ocean, off the northeast coast of Australia.

Dead Sea: is a landlocked salt lake. It is bordered by Israel on the west and Jordan on the east.

Tasman Sea (Te Tai o Rēhua): part of the Pacific Ocean. It is found between New Zealand and Australia.

Tips: Use the names of these lakes as search words or keywords to find out more about them. Search words, or keywords, are the most important words in your question. You can leave out small words like ‘the’ and ‘of’ and just choose the main ones, eg Red Sea. We can always change our keywords or add more if we need to.
