ABYSSAL STORM

by Ned Kahn, 2001

Conceived in collaboration with the School of Oceanography, University of Washington
Funded by the Washington State Arts Commission

This sculpture allows you to tilt and rotate the elliptical vessel filled with a mixture of water and tiny glass spheres. Depending on the angle that the vessel is tilted, many different flow patterns can be created. These complex flows are suggestive of turbidity currents and undersea avalanches in the depths of the ocean. When the fluid is stirred, the fluidized sediment beoomes dense and can support internal wave motions.

The experiment reminds us of larger scale ocean flows: the 'overturning' of an estuary where a small input of river water drives a much larger circulation, drawing denser ocean water inward, feeding and ventilating creatures living there.

At still larger scale, the entire world ocean is 'overturning', with waters sinking in just a few places in the cold, high latitudes; again a much larger rising motion is then driven that ventilates the oceans of the Earth from beneath.

The apparatus sits like a ship's binnacle, or astrolabe, or an earthly globe, inside the first crest of a glass wave.
