What type of water is found in estuaries?

Back

Estuaries contain brackish water, which is a mix of saltwater from the ocean and freshwater from rivers.

Front

Where do benthic organisms live?

Back

Benthic organisms live on the ocean floor, where they can be found in various habitats.

Front

What technology is used for underwater mapping?

Back

Sonar (Sound Navigation and Ranging) is a technology that uses sound waves to detect and map underwater objects and topography.

Front

In which oceanic zone would you find crabs and clams?

Back

Crabs and clams are typically found in the intertidal zone, which is the area that is above water at low tide and underwater at high tide.
