Sounds of estuaries

Sonified data of bends in river estuaries as the ebb and flood flow in and out from the sea. I increased the fundamental frequency of the diurnal tides to 110 Hz to be able to hear them. The bends are reported in our observational paper in Geology(scroll down the list for the Westerschelde).

Listen, this is how the geosphere must sound
and make the harmonies of stellar spheres be drowned.

The sea at river mouths breathes in and out
in the tow of two celestial orbs
on the diurnally revolving globe
and the discharge of a fluvial fount.

The sinuous tideways slowly diverge,
abandoning land for a seashore dirge.
Once the wailing of the ebb egresses,
the foaming flood intrudes to repossess.

Had we been a species of a slower bent,
we could have strived to overhear, like Ents,
emerging from the turning tidal flows
sublunary harmonics of the seaboard,

as scores of bends vibrate their overtones,
and timbre scaled by length of littoral zone,
like, when strings are struck by sweeping bows,
the cello sings and rings its sounding board.
