surface water salinity range
33-37 ppt
brackish waters salinity range
< 25
Hypersaline waters
>40
how do inverts deal with salinity
osmoconformer
How do other animals deal with salinity
osmoregulator
osmoconformer
an organism that maintains an internal salinity that is similar to its environment
osmoregulator
an organism that controls the osmotic pressure of its body fluids

How can the ocean be <0
ocean is less prone to freezing
water temp in sea from
-2-30
thermocline
depth where large change
T or F colder on top warmer on the bottom
F
cold water blank dense
more
higher salinity blank dance
more
how is density determined
temperature, salinity, and pressure
stratification
the layering of the ocean according to density
T or F depths are denser and warmer
F
T or F surface is lighter and warmer
T
How do marine organisms get gas
O2, CO2, N2 are dissolved in water, from atmosphere
What holds more gas warm or cold water?
warm
volume _ on descent vol _ on ascent
decreases, increases
