Larsen Ice Shelf Iceberg

Ross Ice Shelf Iceberg 2000The super-berg B-15--183 miles long and 23 miles wide--broke off the Ross Ice Shelf Last March 2000. By May, it had broken into two parts, as seen in this satellite view,iand drifted about 20 miles from shore. Meteorologist Matthew Lazzara hopes to put reporting weather stations, like the one shown here, on icebergs.

1st National Art Project: Icebergs North on the Red River - Breckenridge to Noyes, Minnesota, 1979-1982

This project requires two years, one for planning (1980-1981); and 1982, the year of its production. Three large red icebergs will be constructed in Duluth, St Paul and Rochester and each will carry a crew of three. They will be in charge of steering as well as other duties which will be explained further into the project. Upon fabrication of the red icebergs, truck, train transportation will deliver them to Breckenridge where a helicopter will place them on the Red River. Ongoing progress will be sound and vision monitored in real time via satellite. The Red Icebergs destination will be Noyes.

Loring Park, a prominently located park near downtown Minneapolis

Terraplane Chorography IV

A variety of sensors were placed in these trees and listened for "silent" wind-jostled sounds from leaf and limb. Simultaneously satellite-delivered Terrain Instrument soundings from Duluth, Minnesota, USA were melded and used twice: during the performance these was amped to speakers in overhead trees nearer to the pond to accompany the dancers; another channel was fed via the Terrain Instrument 202 microprocessor system for assigned outputing into two diagonal speaker-laden planes hovering above the grassy performance pond-site.

Dancers

and Will Swanson with FM transmitter belts.

Interactive choreography site details with background Loring Park Pond where for the duration of their dancing Sharon and Will each listened for possible "zephyrs."

The dancers froze and held their stainless steel wire taut to listen to gusts fed back in realtime from their overhead speakers in the trees. Both dancers broadcast on separate FM channels: each belt's vibrating wire sounds were received by radios within the 202 area and upon amplification were output to speakers overhead. Additionally mixed into these same speakers, when the wind was still, continuous sound via a KSJN, St Paul, Minnesota, USA satellite downlink from Duluth Minnesota could also be heard overhead. (This was fed via a modulated laser from within the Walker Art Center and its beam was received on a front surface mirror afixed to the bark of the Loring tree. At his point the laser beam was simultaneous split and one beam was directed to another front surface mirror attached to the anchored 202 microprocessor. The laser demodulator translated the light back itno its analog components and these were input into amplifiers which fed the overhead tree's speakers. The diagonally positioned 200 speakers (visible above (r, corner) were playing unique and detailed tree sounds processed via direct output hard wiring into the 202 microprocessor for realtime manipulations. Following the performane beneath the expansive canopy of trees listener, their sources were approximately fifty feet distant (as seen in the top image below the map). The tree-laden speakers are now silent at this point.

From the Walker Art Center, Duluth Terrain Instrument sounds were beamed to the site via modulated laser which was amplified in adjacent, overhead trees.

200-5 inch speakers coalesced the output from nearby trees (branches, leaves, limbs) via the Terrain Instrument 202 and processed these sounds through its Intel 8080 microprocessor. The result was a hovering and pillowed spatial envelope. return to data poetry
