One can categorize ocean currents into two broad groups. The first are the currents that are wind driven. These currents are most intense near the surface of the ocean. Their principal role is to transport warm equatorial waters toward the Polar Regions. The second class of currents are those that are driven by density contrasts with the surrounding waters. In this latter group are the deep, or abyssal, currents flowing along or near the bottom of the oceans along the continental boundaries. Their principal role is to transport cold, dense waters produced in the Polar Regions equatorward (and beyond). Taken together, the warm surface currents and the cold abyssal currents are the means by which the ocean convectively overturns, mixing incoming solar heating meridionally and vertically into the ocean interior.

一个人可以将洋流分为两个大群。第一个是风驱动的电流。这些电流最强烈，在海洋表面附近。他们的主要作用是将温暖的赤道水运送到极地地区。第二类电流是由与周围水的密度对比驱动的电流。在后一组中，沿着大陆边界沿着海洋底部或附近流动的深层或深渊电流。他们的主要作用是运输在赤道（及以后）的极地地区产生的寒冷，密集的水。综上所述，温暖的表面电流和冷深透射电流是海洋对流倾覆，将传入的太阳能加热混合到海洋内部的手段。
