A person who specializes in marine biology is called a marine biologist. Marine biologists use various tools to study the oceans. These tools include sampling methods, such as plankton nets and bottom trawls, underwater observation using remotely operated vehicles and tracking devices, such as hydrophones.

A marine biologist’s goals can include alleviating ocean acidification, which has a potential negative effect on marine life, assisting the seafood industry in providing sustainable food to consumers or discovering new compounds that can be used to make medications.
