More Sea Stuff

Clines- the sudden change in the ocean due to depth,

• pycnocline- density
• thermocline- temperature
• halocline- salinity
• Salinity- measured in parts per thousand, average salinity 35 parts per thousand
• Salinity increases when water is taken from the ocean- sea ice, evaporation or more salt is put in the ocean, land runoff
• Salinity decreases when water is added to the ocean.

Be sure to review your handouts that demonstrated ocean currents.
