what technology is used to study the neritic zone?

Answer 1

Acoustic Technology -
a technology that utilizes sound in the ocean to "see" underwater. Sound travels through water in waves, with different sizes and frequencies being created by different sounds. A large selection of different acoustic tools are used by scientists, generally involving the emission of sound (from a research vessel or other source) and the recording of its reflection off different surfaces (the ocean floor, fish schools, etc.) in its path. This acoustic technology, commonly used to track submarines, has advanced in recent years and has become a primary tool for oceanographers, both for mapping the physical shape of the ocean floor and for tracking and counting marine animals of all sizes. Applied with other technologies, acoustics are a critical tool for Census scientists.
