The word "oceanographically" is typically used to describe anything related to the scientific study of the Earth's oceans and their physical and biological features. However, there are a few different ways to express this concept using synonyms. For example, you could say "marine science" or "oceanology" to describe the same field of study. Another option might be to use adjectives like "oceanic" or "maritime" to describe something that pertains to the ocean, such as an oceanic current or a maritime expedition. Whatever word or phrase you choose, the important thing is to accurately convey the idea of studying and understanding the ocean and its complex ecosystem.
