(Phil) Meany ice shelf, Lake Superior

conceptual realtime international listening site linkable via passaroundsound.net (intlistening nodes)

I wish to re-start this as a permanent project w/a buoy and sensor combination in BAFFINLAD. The configuration shown above depicts the 1977 winter site on the same shelf. This installation was first heard in Chicago, and I was not able to take advantage of my newly acquired triaxial sensor for simultaneously listening to at least three nodes. A fourth node was to have also been heard w/the strand shown above reaching the shore edge.

BELOW An 1984 analog Metrologic ML868 modulautable laser outlined the triangular paths the combination of 16 and 22 gauge wires would trace about a foot above the ice floe. The 3 corner nodes were anchored in the foot-thick ice by turnbuckles and each hole was hand-drilled. This triangulation of wire strands successfully yielded several full track Nagra, 1/4 analog reel-to-reel recordings. From the final front surface mirror, aimed at the shore, black and white video was viewed on a 9=inch monitor input from a Metrologic Radiometer. (no portable reel-to-reel video recorder was available fr/ UMDs non-print Dept.) Surface winds regularly blew dandruff-sized snow crystal into the strands. However, the wire on the right headed back toward shore where sustained recordings were never made because of persistent figure eights by a group of snomobile riders.

Rubber encased Edo Western transducers were embedded beneath the four nodes of the triangulation (top), including the one linked to the shore (above r in closeup) and each sensor was covered with packed ice as shown. A strand was attached to the visible eyebolt. The resulting mound was watered and froze quickly. When finally hacked loose, the rubber coated sensors did survive after monitoring spectacular vibrations. These included a near deafening horizontal lightning-sounded ice cracking, sloshing water below the ice and of course, the snowmobilers (audio archives are in progress) .

*Beastly cold at 35 below zero-in progress: reel-to-reel, '80-'81Meanyiceshelf - the first weekend test mix used the node shown above which had an accelerometer attached to the eyebolt and the hydraphone frozen in place (the mound)- and was broken out later in the day following each session. sensors used, soundings comments: Quiet, releasing ice tension and the persistent rise and fall of ice-undulations underly these excerpted sounds immediately as very wet-water suddenly rises in a thump. An ice crack interrupts following a sloshed wave. Thereafter the mix contrasts watery influenced rumbles from below with wind-blowing dandruff-sized snow crystals impacting a taut stainless steel strand upon intervals on a becalmed lake.

Phil Meany clears the blown snow build-up from beneath and along all the wires. These each had a pair of Columbia Research Lab accelerometers attached at both ends. The encased rubber hydrophones could detect the snowmobilers from miles away. At this point I was hearing sloshing beneath the approximately foot thick ice and pitched motor noises.)

Dutch Elm disease claimed these trees which I found in a nearby alley and were borrowed temporarily.

w/headphines on and preamp in hand, receiving audio could be checked out, tree-by-tree monitoring of the passaround modulated laser's sounds. Following a check of each tree, their front surface mirrors were covered with a matte black cloth. As the evening progressed covers would be removed resulting in an additional sound from the available Terrain Instruments, Oscar Satellite-relayed soundsources.

 

When the matte black felt (pictured above) was removed from its Velcro-hold a mirror was revealed. The sound-modulated METROLOGIC laser beam passed around audio via front surface mirrors among the trees one by one. With each movement of the modulatable-beam, a new sound stream was activated. The room was fullest at the final tree. Ice floe rumbles, Sferics and counterpoint snow crystals signaled the performance conclusion.

 

Reel to reel tape recordings were made at earlier times on or near the Meany Lake Superior inlet. The extraterrestrial Sfercs were listened to using a home made wooden framed receiving antenna/monitor mounted vertically and anchored to a shoreline outcropping. This large copper-wound loop receiver was after the Calvin R. Grafs's design of 1978. The resulting high pitched streaked-sounds were recorded on a Nagra 4.2L recorder. Studio amplifiers from an equalized telephone pair received these natural radio noises in Chicago-- sent via shortwave radio to the amateur Oscar 1 satellite-- and output these Imported Sources into the speakered gallery space below.
