Prospectus: In "Occidio" I wish to create an installation that (re)presents scientific visualizations of global warming in the form of a sound and video installation. The work employs National Aeronautics and Space Administration (NASA) public domain scientific visualizations created from Earth Observation Satellite data. The animated visualizations document changes in atmospheric chemistry, land biosphere, sea temperature, etc. The data are archived and visualized at Goddard Space Flight Center, Greenbelt, MD. The data used in this version of the installation shall focus upon Antartica. A data thread will therefore be extended from orbit, through the atmosphere and continental shelf of the Antartic, to the Virtual Mine. Form and Installation: In the proposed installation of "Occidio" I wish to employ a video projector; optical theremin sound devices; a sound mixer; two amplifiers; and 4 speakers. Sound shall be produced through the interaction of optical theremin units as stimulated by global warming data projections. Optical theremins produce a sine or square wave sound form that varies in pitch as light is modulated over a photoreceptor. The theremin's photoreceptors would be placed directly in the light path of the video projection. Hue and value changes would modulate the audio tones to "perform" different sounds. The placement of the theremin's photoreceptors would be spatially panned in a stereo sound field as right, left, center, etc. The installation's multi-channel sound environment would therefore interpret the global warming data with changes in sound pitch and duration, and through the locational placement of sound in a stereo image surrounding the viewer in the installation space. I consider the abstract yet elegiac sound resulting from this work to be a form of "music," if one interprets the term quite loosely and conceptually, and as an alternative means of interpretation of scientific data.
