Temperature and salinity
ocean currents are caused by difference in temperatures and salinity lol :) :P hehe
The global current conveyor belt begins on the surface of the ocean near the pole in the North Atlantic.
Glocal winds: they occur when different winds cause currents to flow in different directions. The coriolis effect: The apparent curving of the path of a moving object from an otherwise straight path due to the Earth's rotation. Continental deflections: When surface currents meet continents, the currents deflect, or change direction.
A geostrophic current is an oceanic flow in which the pressure gradient is balanced by the Coriolis effect. The direction of the geostrophic flow is parallel to the isobars.Ê
Temperature and salinity
There are different kinds of process that deeply affects the salinity of ocean water. Continental deflections, Coriolis Effect, convection current and also evaporation.

An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon the water, such as the wind, Coriolis force, temperature and differences and salinity tides caused by the gravitational pull of the Moon and the Sun. Depth contours, shorelines configurations and interaction with other currents influence a current's direction and strength.
Temperature and salinity drive ocean circulation by altering seawater density. Warm, fresh water is significantly less dense than cold salty water and will therefore rise to the top in the ocean. Any process that alters temperature or salinity (such as rain, sea ice formation or seasonal variation) will change the density of the water and allow it to move in the water column, causing circulation of water on a global scale. This is known as thermohaline circulation. Because things such as rainfall and temperature tend to be relatively constant in a given area over a long period of time, a set current of water known as the global conveyor belt has arisen. It plays an incredibly important role in heat transfer over the earth.
By, instead of a straight current, makes the current curved due to the Coriolis Effect.

Deep Currents Occurs when the density of the water increases. Density is based on two main things it is the Salinity is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. Salinity (how much salt) of the water and low temperatures.
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
The term thermohaline circulation ( THC ) refers to the part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes
