Hello Sven. Thank you very much for the fantastic , incredibly educational presentation on ocean circulation. I find it thoroughly enjoyable and you do a great job explaining the complex subject.
Hello Sven. I’m enjoying your lecture series very much, just to further my own knowledge of the subject of oceanography and thank you for having prepared the presentations. Is there a particular textbook or textbooks which you could recommend & is there a particular point of purchase ?
Pressure chimneys. Cold surface water contracts & makes a surface dent, water flows to fill it and makes the column to the sea bed higher pressure (more weight above it) so it shoves water towards equator and beyond. Deep water leaving makes the entire column drop so now there's a surface dent again and so on, it's unending until the deep pressure along it path rises to match its higher pressure or its own pressure decreases because its surface water heat. Ice forms in pancakes if its cold enough, and wind blows the low-salt pancakes away making a surface dent, salty water around flows into the dent, now its saltier so its heavier. As long as it has a horizontal path at a depth range it can go on for ever. When the water its shoving gets shoved into a cul de sac (sea bed rising) it lifts the entire ocean above it like a wedge and that makes a surface bulge so surface water runs down hill off the bulge back to where it came from. That's a long-distance overturning circulation like 25,000 km or 40,000 km, whatever. Simple stuff.

Slip of the tongue gyre mis-named at 12:48 see 17:52
How can we explain upwelling or downwelling in the poles and the gyres?
