A Mediterranean Mystery [with a Saros solution]

Interesting empirical evidence from the sunny Mediterranean points to geo-effective lunar cycles altering tidal ranges.


A Mediterranean Mystery

The waters of the Mediterranean are relatively calm and on a still day the sea at my favourite beach [Almayate – which is close to Malaga, Spain] can be as calm a millpond.

The tidal range at Almayate is [as Wikipedia states] very limited.

Being nearly landlocked affects conditions in the Mediterranean Sea: for instance, tides are very limited as a result of the narrow connection with the Atlantic Ocean.

The Mediterranean is characterised and immediately recognised by its deep blue colour.


The sea currents at Almayate are also fairly benign.

Evaporation greatly exceeds precipitation and river runoff in the Mediterranean, a fact that is central to the water circulation within the basin.

Evaporation is especially high in its eastern half, causing the water level to decrease and salinity to increase eastward.

The salinity at 5 m depth is 3.8%.

The pressure gradient pushes relatively cool, low-salinity water from…

    Over the years I have noticed even very small bodies of water have “tides” that slosh from side to side as well as end to end. Wind and gravity changes set up the motion and the shape of the basin set the frequency…pg

    The Saros is almost 16 full moon cycles. A total of one full moon cycle is ‘lost’ about every 2300 years but humans aren’t going to notice that in everyday life.

    The numbers are: 255 Saros = 4078 full moon cycles
    (255 x 16 = 4080)
