1. Geography of the Ocean

   • Seamount
   • Ridge
   • Trench
   • Rift Valley
   • Abyssal Plain
   • Mid-Ocean RIdge
   • Volcanic Island
   • Continental Shelf
   • Continental Slope

2. Water Column Profile

   • Temperature
     • Density
       • Salinity
       • Bouyancy
   • Pressure
   • Thermocline
     • Different layers of different temperatures
   • Pycnocline
     • Transition from one density to another
   • Halocline
     • Layers of Salinity

3. Water Movement

   • Surface Currents
     • The Gulf Stream
     • Gyres
       • Large rotations of surface water around the world
     • Downwelling
     • Waves
   • Deep Currents
     • Global Conveyor Belt
       • Thermohaline Circulation
         • Upwelling
           • El Nino
             • can sometimes affect upwelling and cause downfalls on the economy
         • carries a lot of heat due to high heat capacity

4. Gas Exchange

   • Photosynthesis
     • CO2+ Nutrients = O2
       • The O2 that is created gets eaten by Phytoplankton which then kick starts the food chain
   • Decomposition/Respiration
     • 02= CO2+ Nutrients
