Wave Motion
Consider these photographs of waves interacting with the basalt columns of Giant’s Causeway at low time to be a sequel to “Kelp” “Tide”. “Movement,” and “Movement Redux.”

concave vs. convex
Canon’s 24 mm “L” lens saw first light on this tour, was indispensable towards the end of our round of the island. Here the camera is mounted on a Manfrotto studio tripod with a hydrostatic ball head. A 0.6 neutral density graduated filter brought out the sky details though I could not catch the foreground polygons without darkening the far basalt columns.
My position is close to the photographs of all the posts since “Basalt Columns.” Here are two photograph of the pavement effect, walking across column tops. Notice the concave facings, identified by dried seawater pools (white circles), the boss of convex surfaces.
I released the tripod “panning” control, searching for the best aspect.

Which predominates in this series: movement or rest?
Full series of kelp in the waves. In these images I heightened the contrast of yellow-brown algae strands against dark water.

to and fro
Photographers can spend years on the Ireland north coast understanding the play of light on water.
Our springtime evening, a few short hours, are here in this series. Today, a series of two photographs of kelp at low tide, moving with the waves. I see the possibility of a long exposure capturing the movement in one shot.
In which direction is the water/wave surge?

Low Tide in a Long Spring Evening
Arriving at low tide, long exposure shots of surf on the pavement was not to be. Here is a rising slope of Giant’s Causeway polygonal columns, dark color marking the usual tidal high point. Above is a measuring stick.

Behind where I stood for the above photo is a channel, perennially flooded at low tide evidenced by the thick growth of brown algae swaying back and forth with the waves.
Low Tide in a Long Spring Evening
Our Giant’s Causeway visit was during a long spring evening, low tide. The long strands of a kelp forest curling.

Articulated Building Blocks — HAPPY FATHER’S DAY
“List of places with columnar jointed volcanics” is a Wikipedia page, over a hundred sites across the globe and high resolution images of Mars, these columns of Giant’s Causeway are no less marvelous for being the most famous of a phenomenon well documented.
A pile of articulated blocks, ready for assembly, next to orderly placed columns forming a pavement into the sea. Across the way, on the Isle of Mull, Scotland, a matching pavement. “Jointed” means one surface of each block is convex, the other concave, two blocks fit together.
