#14 - Space units of the ocean tides.
.1 The ocean tides are cyclical variations of the water level.
.2 In this sense, the ocean tides have not a single space unit, the Earth; but many space units, the “tide basins”; each of them has its tide.
#15 - The tide basins.
.3 A tide basin is where an ocean tide takes place.
.4 There are numerous tide basins, which may be small, large, big, enormous.
.5 Inside each basin there is one tide system.
The tide basins as clock faces.
.6 A tide basin is analogous to a clock face, where, its hand, the tide wave, goes around its centre, the amphidromic point (figure #1).
.7 From high above, the tide wave is seen to move near the coasts, clockwise if on the southern magnetic hemisphere; counter-clockwise, if on the northern magnetic one.
.8 May be, with the exception - I do not know whether real, or apparent - of what occurs around the New Zealand.
.9 Basin of the North East Atlantic, where tides occur twice a day, as in the majority of basins.
Figure # 1
At the passage of the Moon on the meridian, the high tide is where the red line is. At the successive hours, the high tide wave moves to the successive lines, counterclockwise.
.10 In a tide basin, where the tide cadence is semi-diurnal, the tide wave takes, on average, 12 hours and 25 minutes to go round completely.
.11 While, in a tide basin, where the cadence is diurnal, it takes 24 hours and 50 minutes.
.12 Moreover, there are other minor tide patterns.
