State the two general patterns of global ocean circulation.

The Patterns of Ocean Currents related to Salinity, and Temperatures is called the thermohaline circulation (Thermo = Heat, Haline = Salt.)., Sometimes called the Thermohaline Conveyor Belt, This Circulation Pattern moves cold water around the globe in deep water currents, and warmer water in surface currents.

Ocean Circulation is the large scale movement of waters in Winds Drive Surface Circulation, and the cooling and sinking of waters in the polar regions drive deep circulation.
