This question seems to be deficient. However, there´s enough information to find the right answer.
Answer:
Deep currents: they develop far below the surface. They are influenced by water density, salinity, and temperature. Example: the Antarctic Bottom Water.
Surface currents: They appear close to the surface. They carry heat from the tropics to the polar areas. Example: the Kuroshio Current.
Explanation:
There are two types of ocean currents: surface ocean currents and deep ocean currents.
Deep currents happens far below the surface, such as at the Antarctic Bottom Water. They are influenced by water density, salinity, and temperature.
Surface currents happen close to the surface and they carry heat from the tropics to the polar areas. For example, the Kuroshio Current is found in the North Pacific Ocean.
