shadows on the waves
frozen on the phone moments
caught once forever
Barriers such as islands and breakwaters intercept the normal transmission of wave energy and thus create a sheltered area in the wave lee from which waves are excluded.
This sheltered area is called the zone of wave shadow.
The size and location of the shadow zone can have great importance in the protection of the coastline and coastal structures and in the control of the longshore transport of sand.
Further, the wave shadow phenomenon can be used as an aid to navigation as evidenced by the early Micronesians and Polynesians and the early explorer-navigators who used the shadow zone disturbances of Pacific islands for island-to-island travel.
Wave shadow by John R. Dingler In: Beaches and Coastal Geology. Encyclopedia of Earth Sciences Series. Springer, New York, NY. (1982)
A shadow on the waves, brought in by the tide from the sunlight shining as is passes overhead.
A lot of intersections of the moment to be captured by the magic of a smart phone.
