Explanation:

1.

An oceanographer studies the ocean, so they are a marine scientist (related to the sea/marine environment).

Sections of oceans more or less surrounded by land are seas (e.g., Mediterranean Sea, Baltic Sea).

Sea level that varies with tide and place is local sea level (specific to a location).

Answer:

marine
