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.

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.

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.

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.)

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.
