Question
Two answers required. The vertical distribution of these two quantities is discretized in a namesake staircase maintained by double diffusion. For 10 points each:
[10h] Name these two quantities, which also drive a system whose major components are AABW and NADW.
ANSWER: (ocean) temperature AND salinity [accept descriptions of salt concentration for salinity; prompt on thermohaline circulation or THC by asking “what two quantities drive it?”; prompt on answers mentioning T or H by asking “what quantity does this variable represent?”]
[10e] Temperature, salinity, and wind are major drivers of these water movements. One of these water movements explains why the climate of Western Europe is more temperate than that of Canada despite similar latitudes.
ANSWER: ocean currents [prompt on the Gulf Stream by asking “which is an example of what phenomena?”]
[10m] The “global ocean conveyor belt” driven by thermohaline circulation flows perpetually eastward in this body of water. A convergence belt at its boundary is home to huge numbers of krill.
ANSWER: Southern Ocean [or Antarctic Ocean] (The major components of Atlantic meridional overturning circulation are Antarctic bottom water and North Atlantic deep water.)
