Ekman Transport
the change in wind direction with altitude caused by the varying effect of surface friction
Thermohaline Circulation
the global, density-driven circulation of the oceans
Upwelling
an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient rich water towards the ocean surface, replacing the warmer, usually nutrient-deplete surface water.
Gyres
a circular or spiral motion, especially a circular ocean current.
Specific Heat Capacity
the amount of heat, measured in calories, required to raise one gram of a substance by one Celsius degree.
Buoyancy
the upward force on an object produced by the surrounding fluid in which it is fully or partially immersed, due to the pressure difference of the fluid between the top and bottom of the object.
Density
the mass per unit volume of a substance
Salinity
how salty the water is
Thermal Forcing
buoyancy differences caused by differences in temperature
Haline Forcing
buoyancy differences caused by differences in salinity
NADW
North Atlantic Deep Water
