- 1ThermoclineRegion of rapidly changing temps below mixed layer; varies with seasons, permanent in tropics and uniform in poles
- 2In-situ Temperature(T) The measured temperature from observation
- 3Potential Temperature(theta T) The temperature a water parcel would have at the surface, if it were raised to the surface adiabatically (=can't gain or loose heat). It also removes the effect of pressure on temperature.
- 4Salinity-Total amount of dissolved material in seawater
- 35 ppt = 35gm of dissolved material in 1kg of water - 5Density(roe) Is a function of temp., salinity, and pressure working together. The average ocean ___ is 1027 kg/m^3 (or in-situ sigma = 27)
- 61 decibar= 1 meter
- 7sigma t-Density that the same particle of water would have if it were at the atmospheric pressure and removes pressure's huge effect on compressibility
- 8Potential Density- density that a particle of water would have if it were raised to atmospheric pressure without it gaining or loosing heat
- Removes pressure's huge effect on compressibility and much smaller effect on temp. - 9T - S DiagramTemperature vs. salinity
- 10CabbelingNon-linear effect of temperature mixes two dense water masses and becomes an even denser water mass
- 11In-situ Density(sigma)
- Never used for deep water because pressure messes with data - 12StabilityThe measure of the water column's tendency to move vertically
- 1330 degrees North and 30 degrees SouthHighest salinities are at these latitudes because of the closeness to the equator where evaporation is greater than precipitation occurs
- 14Why Oceans CirculateThe unequal heating of the ocean surface by latitude.
