Introduction
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.

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.
