Ocean Properties and Instruments

Question 1

Sensible Heat

Answer 1

• Temperature change with NO phase change

Question 2

Specific Heat

Answer 2

• Temperature required to raise to 1^º

Question 3

Latent Heat

Answer 3

• Heat required for Phase Change, but no temperature change

Question 4

Mixed Layer

Answer 4

• Layer of almost uniform density resulting from the mixing of stratifying and destratifying processes.
• Located from the surface of the ocean to the top of the pycnocline

Question 5

Thermocline

Answer 5

• Oceanic water layer where water temp. decreases rapidly as depth increases

Question 6

Isothermal

Answer 6

• Term for the condition where sea water’s temperature is uniform from the surface to the bottom

Question 7

Deep Layer

Answer 7

Deepest layer of the ocean. About 1000m down

Question 8

Salinity

Answer 8

Total amount of dissolved nonorganic and nonvolatile material in seawater

• Sp = Practical Salinity
• Source of ions: Eroded rocks
• Salinity goes up, density goes up

Question 9

Conductivity

Answer 9

Also determines the salinity of the water

• Usually how much salt or material is in the water

Question 10

CTD

Answer 10

Conductivity, Temperature, Depth
