Where is the subtropical mode water in the North Atlantic?
What are the water masses at approximately 1000 m in the salinity section?
look at the surface at $\gamma^n=27.22$ and $27.95$.
what depths are those in the Atlantic?
where is the salty water coming from?
In the water deeper than 1500 m compare and contrast the salinity section in the Atlantic to that in the Pacific.
sketch which way you think various water masses are moving
what are the names of the two deep water masses?
where are they formed?
Based on Oxygen along the $\gamma^n=28.05$ surface, how does the water along this surface flow?
Overturning Circulation (OU 6.6)
Based on fig. 6.44, where in the world oceans is dense water produced? and in what proportions?
How strong is the overturning circulation believed to be in the
Pacific?
How does the strength of the overturning circulation get
estimated?
If the Pacific Ocean has an area in the horizontal of 10000 km x
5000 km, what is the velocity associated with the upwelling?
How does the path of the NADW differ from the overturning in the
Pacific?
Dense water pours into the basins (i.e. North Pacific). What happens to it, assuming the Pacific is in steady state? i.e. it has to rise and come to the surface again. How?
