What is the sea?

Sea is a general name for the body of saltwater that covers part of the surface of the Earth.

The largest sections of the sea are called oceans.

In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet.

Oceans cover nearly 71 percent of Earth’s surface.

New Zealand has 15,000 kilometers of coastline making it the 9th longest in the world.

New Zealand’s coastline borders the Tasman Sea and the Pacific Ocean.

The Tasman sea was named after the Dutch explorer Abel Janszoon Tasman.

Abel was the first recorded European to encounter New Zealand and Tasmania in 1642.
