Thermoclines are typically not found below this depth regardless of season and latitude:

• 10 meters

• 100 meters

• 500 meters

• 1,000 meters

• temperature

• salinity

• turbidity

If all else is equal, increasing the salinity of a seawater sample will also increase its:

• temperature

• pressure

• density

• turbidity
