Flashcards in Physical/chemical Oceanography Deck (16)
Characteristics of salinity
Made of electrically charged Na+and Cl ions
Salinity lowers freezing point and increases density.
What is thermocline?
What is pycnocline?
Change in density
What is diffusion?
Low to high concentration
What is osmosis?
High to low concentration
High heat capacity
What is one atmosphere of pressure?
33 ft, 14.7 lbs per sq. inch
What is the oxygen minimum layer?
The area in which 02 gets used up; underneath marine snow causes it to increase again,
Characteristics of active margins
Tectonic activity, subduction
Characteristics of passive margins
Despositional, on coastlines
Characteristics of sound in water
4 times faster, up to 60 times louder, travels farther
What is Osmoregulation?
Change with internal salinity
What is an osmoconformer?
Change with outside salinity
What is isosmotic?
Same salinity inside and outside
What is hyperosmotic?
