Under the Sea Floor (Coring and Strata) originated in a University of Oslo (Norway) research project where a 10-meter long core-sample was taken from a ‘pockmark’ in the Oslo fjord, 32 meters below sea level. For two days I hovered in the background on a research ship and on a drilling vessel, recording sounds from on deck, below water and on the sea-floor. From these recordings came one set of two sound-types used in the work. The second set of sounds originated from a seismic shot created by a large TNT blast in a quarry. This shot was recorded by an array of 2000 geophones spread over tens of kilometers. The sound on each geophone is about 15 seconds long, and records the response from the Earth’s crust and well into the mantle. This data was used to synthesise sounds and control the transformation of other materials. The two types of sound create two clear sections to the work. In the installation they play simultaneously in adjacent spaces. In this special remix they play consecutively.
