Oceanography is a broad field, so there are actually several specialties within oceanography that focus on these specific phenomena:
* Physical oceanographers study the physical properties of the ocean, including tides, waves, currents, and temperature.
* Coastal oceanographers focus on the interaction between the ocean and the coastline, including the dynamics of tides and waves along shorelines.
* Marine geologists study the geology of the ocean floor, including the influence of tides and waves on geological formations.
So, depending on the specific focus of their research, the scientist could be called any of these.
