tidal flow


These truly massive whirlpools form when conflicting tidal flows meet. The swirling vortex is powerful enough to pull in swimmers and small boats. The most powerful is Saltstraumen, located outside Norway.

Jack emerged from down below with a big smile. “I’ve synced the navigation computer with the Hub. Gwen’s calculated the likely tidal flows of last night, so we’ll follow that out to sea. And if there’s so much as a flutter of wings from anything in the water, the sensors in the bow will pick it up and adjust our bearings. So, sailor boy, all we have to do is sit back.”

“Can I not… you know,” ventured Ianto.

Jack knew what Ianto wanted to do, and it wasn’t every day you got to cruse past the assorted sailors and yachters out on a blowy day in the Bristol Channel. “If you want to stand by the wheel looking cool, that’s okay with me,” he grinned.

Ianto slipped on a pair of shades and stood proudly on the deck.

Myxilla incrustans

…is a species of encrusting Myxillid demosponge which ranges from the Faroe Islands, off the coasts of Norway south along the Atlantic to the Mediterranean Sea. M. incrustans is typically found between the low water mark to a depth of 400m, where it will encrust on vertical rocks and areas exposed to tidal flows. 

M. incrustans is also known to occur in the North west Pacific Ocean and in Japanese waters where it is typically known to encrust the shells of clams in the genus Chalmys

“Tide Flow - Time Flow”

Mirrored Stainless Steel Figures Approx 1.85 mtrs High

Installation at the Caol Ruadh Sculpture Park 2012  on the kyles of Bute, Argyll, Scotland

Exhibition open from 24th June to October 2012

Rob Mulholland’s latest installation ‘ Tide Flow – Time Flow ‘ is part of a group exhibition at the newly opened Caol Ruadh Sculpture Park overlooking the Kyles of Bute, Argyll, Scotland.

“‘ Tide Flow – Time Flow ‘ has been installed on the shores of the Kyles of Bute. As the tide ebbs and flows, the reflections of the sun and sea constantly alter the appearance of the mirrored stainless steel forms creating a kinetic surface that moves to the rhythm of the sea. The Cretaceous sea-forms, standing alongside the human figures, are a reference to our genetic past and ask us to consider our evolutionary journey thus far. ”
