greater near the equator


b. greater near the geographic north pole of the Earth


c. greatest on the western boundaries of the ocean


d. least on the western boundaries of the ocean


e. none of the above



Our research on surface circulation used drifter buoys to _______________


a. measure pressure changes in the mixed layer


b. measure salinity differences in the thermocline


c. analyze the annual mean current velocity


d. measure vertical motion with the mixed layer


e. None of the above methods



What happens to the temperature of the sea surface water, during the spring and summer, with distance away from the coast of northern California?


a. it gets cooler


b. it gets warmer


c. the temperature stays the same


d. the temperature changes according to the depth only


e. none of the above



How do eastern boundary currents influence coastal climate?


a. carry warm water away from the equator, creating a humid climate along the coast


b. carry warm water away from the equator, creating a cool, dry climate along the coast


c. carry cold water towards the equator, creating a cool, dry climate along the coast


d. carry cold water away from the equator, creating a humid temperatures along the coast


e. none of the above



What could potentially stop or slow down the meridional overturning circulation, causing cooling in the North Atlantic regions along western Europe?


a. increase in surface water salinity in Antarctic


b. increase in freshwater runoff into the Arctic


c. increase in CO2 in deep water in Arctic


d. decrease in freshwater in Antarctic


e. increase in oxygen in Arctic waters



How is it that heat in the surface of the ocean near the equator affects regions north of the equator?


a. The ocean absorbs heat from the sun near the equator, and travels north with the surface currents.


b. The ocean absorbs heat from the sun near the equator, and travels north in deep currents.


c. The ocean absorbs heat from the sun near the equator, and travels north in both surface and deep currents


d. Downwelling removes heat at the equator from the northern regions.


e. The heat absorbed at the equator does not affect northern regions.



Why has the use of ARGO floats been a major improvement over older ocean temperature measurements made in engine rooms on ships?


a. ARGO floats measure both water temperature and salinity, both not possible at same time in water samples on ships


b. ARGO buoys confirmed the accuracy temperature measurements made using previous methods on oceanographic ships


c. ARGO buoys measure warmer temperatures in the ocean than made by ships.


d. ARGO floats measure water temperature within the ocean, and are therefore not biased by the influence of heat produced by ships.


e. None of the above answers.
