Juneau, Alaska, 15 Nov 20, High-Low Tides: 6 hrs @ 20 sec interval = 600x speed High=20.4, Low= -4.4, Total=24.8 ft
Juneau, AK, high and low tides 15 Nov 20 PM, at 1 frame / 20 sec = 600x speed increase.
High = 20.4 ft Low = -4.4 ft Total = 24.8 ft water level change in 6 hours: That takes a lot of energy; that’s why the moon’s distance from Earth is increasing. 24.8 is an unusually high water level change in 6 hours. Average for Juneau is probably ~ 14 ft change in 6 hours. A lot !
Notice: At beginning, tide is still rising. At ~ 48 sec, tide begins to rise again: watch the dock lights, on right.
Will try again in Spring, with longer daylight, to get a good 6 hr + cycle, flood or ebb, at a typical Spring extreme total water level change..
