Amarine scientist wants to understand the effects of pressure on deep sea organisms. unfortunately, the harsh environment of the deep sea makes it difficult to make long-term observations in areas of high pressure. what research method would best allow him to overcome this limitation in studying these organisms

Using submersible would be the best method that allow him to overcome the limitation like pressure in studying organism in the deep sea.

A submersible is a small vessel made up of high-quality metal made for underwater research that can bear the high pressure of deep sea. Submersibles are different from submarines because submarine is used mainly for defense purpose by navy.

Submersibles can be both unmanned and manned. In manned submersible, it has a glass window through which scientists can observe the deep-sea creatures and a light source which enlightens the dark area in the deep sea.

Unmanned submersibles are remotely controlled and have fitted cameras that provide information to the scientist so they are called remotely operated vehicles(ROVs).
