Tides

[johnm33]

The average influx throught the Bering Strait is around 1Sv which equates to one million m3 per second. So your hypothetical 200.000 m3/day back and forth is only about 2 m3/s!

1x2=2 2x2=4 so my hypothetical is 400,000m³ dropping off the continental shelf every day over and above that induced by the regular/residual current, and it's not about speed but inertia, both flows will rotate and both will have eastward inertia. If it was merely 'sloshing about' then the same water would move back and forth, it doesn't due to both it's density and inertia and this is also why there is a continuous, and I believe increasing, inflow and exchange shaping the ice in Chukchi and Beaufort.

Thought I'd take a look at the seabed of the area, starts at -50 then 70>90>120>150m. Began to look at flow but lost connection. The second ani. is a snapshot in time looking at flow at various depths, so may or may not be typical. -10 to -70 in 10m jumps click

In the first gif I went for -36m it being 2/3 of 56 more or less the depth through the strait; not as I anticipated. In the second it appears to be a surface model despite it's claim, this one is the course of a day.

Previously I used the analogy of a flywheel to try to illustrate the effect tides have on currents perhaps a swing or pendulum would have been better, where each tide a small push adds momentum. It now appears that the resistance to incoming Atl. waters is waning and taken with the apparent connection to the flow in at Bering I suspect a greater exchange of waters will occur through Fram, if it isn't already happening, but even then an acceleration.
This has to be taken into account when thinking about the AMOC, since it will have two opposing effects, the N.bound flow will be eased but an equal amount of torpid Arc. waters will have to be brought up to speed by mixing along the N.Am. coast, so slowing things down. A Good proxy may be a small sea level rise along that coastline.

This illustrates the inflow by Chukchi/Wrangel over the past year.

This is to look at a possible connection between Bering and Fram, it says -200mts. but I think it's the surface, look at Bering it's only 50odd mt's. deep. It's hourly over the course of a day cherry picked new moon for enhanced effect.
Second gif is at -92.3mts. daily from new moon to new moon.
This third gif is just to see how changeable the arrows are over 12hrs., doesn't prove anything but they're more consistent than I expected. The 'full' new moon is about half way through. How that fits in with tidal harmonics hereabouts
