Parts of ocean

Question 1

insolation

Answer 1

amount of sun hitting earth

Question 2

isotherm

Answer 2

lines of equal temp

Question 3

ocean circulation

Answer 3

carry warm water to poles on west, cold water to equator on east

Question 4

temp/depth relation

Answer 4

temp decreases with depth

Question 5

mixed layer/surface layer

Answer 5

surface layer, heat by radiation, mixed by wind, driven by density

Question 6

thermocline

Answer 6

temp gradient

Question 7

deep water

Answer 7

below 1000m

Question 8

tropics

Answer 8

permanently stratified thermocline, mixed layer separated from cold layer by thermocline

Question 9

poles

Answer 9

no thermocline

Question 10

temperate

Answer 10

seasonal thermocline due to storms, after winter thermocline weakens and temp decreases, comes back in spring

Question 11

halocline

Answer 11

salinity gradient

Question 12

density increases when…

Answer 12

salinity/pressure increase, temp decreases

Question 13

pressure increases with…

Answer 13

depth

Question 14

pycnocline

Answer 14

density gradient

Question 15

transition layer between

Answer 15

surface and deep layer

Question 16

isopycnals

Answer 16

lines of equal density

Question 17

ocean layers

Answer 17

surface layer, pycnocline, deep layer

Question 18

surface layer

Answer 18

100m, less dense top layer with dense below

Question 19

pycnocline

Answer 19

transition layer between surface/deep

Question 20

deep layer

Answer 20

poles water cools/sinks and flows to equator

Question 21

saturation value

Answer 21

amount of gases water can hold at equilibrium

Question 22

saturation/solubility relation

Answer 22

higher saturation gas higher solubility

Question 23

solubility/saturation increases…

Answer 23

as salinity/temp decrease and pressure increases

Question 24

supersaturated

Answer 24

when there’s more gas than should be

Question 25

where are gases exchanged

Answer 25

surface layer

Question 26

when gases diffuse

Answer 26

storms/waves

Question 27

where gases come from

Answer 27

respiration/photosynthesis, both in and out ocean

Question 28

where is most oxygen

Answer 28

most in surface layer, least in pycnocline

Question 29

oxygen minimum layer

Answer 29

coincides with pycnocline, lots of organisms consuming oxygen, surface layer cant sink, 150m-1500m

Question 30

anoxic water

Answer 30

contains no oxygen

Question 31

amount of light entering ocean depends on

Answer 31

height of sun, smoothness of ocean

Question 32

wavelength absorbed first

Answer 32

long

Question 33

sound speed increases as

Answer 33

temp/press/salinity increase

Question 34

sound and pycnocline

Answer 34

sound increases above/below, decreases in pycnocline

Question 35

land/ocean evaporation/precipiation

Answer 35

land- precipitation exceeds, ocean- evaporation exceeds
