This is an earthlike planet in every respect (same 24 hour day, same orbital year, etc) except it is an ocean world. There are no continents, and the global ocean is significantly deeper (10 miles, or deep to the point the topography of the ocean floor would have little role in the shape of the currents.) I assume the main factors here would be tidal forces of the sun/moon, the Coriolis effect, maybe sun exposure and wind currents, and the formation of ice caps at the poles.
I've poked around quite a bit and found a textbook covering surface gyres that states "wind-driven surface currents only affect the top 100-200m of water, which I would assume would mean these currents move with the circulation of the planet's atmospheric cells and jetstreams.
What I would like to know is what the deep-sea currents of this ocean world would look like. Would they emulate the currents of the atmosphere?
