What Oceanographic topics should a Marine Roboticist know

Hello!

I'm a 3rd year computer engineering student who is aiming to go into marine robotics, especially interested in the intersection of underwater acoustics and autonomous localization and navigation. I have been primarily focusing on the engineering topics associated with the field, such as signal processing and robotics software, but would also like to learn more about oceanography as a whole. Not as much getting really deep into the nitty gritty of the models and calculations of the field necessarily, just wanting to know enough of the topics to understand the environment AUVs have to navigate and to better understand the areas oceanogrphers are using these devices to make new discoveries.

Any help would be appreciated!
