Whistler's Impulse (2014)


Written for the MAARBLE (Monitoring, Analyzing, and Assessing Radiation Belt Loss and
Energization) project’s “Sound of Space” Musical Composition Contest. The competition guidelines
required the integration of recordings of “Earth Sounds” made by the MAARBLE team using a Very
Low Frequency (VLF) receiver. These recordings captured five types of electromagnetic phenomena
that occur in the space surrounding the earth: Sferics, Tweeks, Whistlers, Dawn Chorus, and Hiss.
Sferics is short for “atmospheric” because these result from lighting strikes. These propagate a great
distance, bouncing between the earth’s surface and the ionosphere. Their dynamic spectra are
characterized by vertical lines indicating a simultaneous arrival of all radio frequencies. As Sferics
travel farther around the earth their spectra stretch due to higher frequencies traveling faster than
lower frequencies. These stretched Sferics are called Tweeks and are characterized by the non-
simultaneous arrival of their spectra. Whisters are the result of thunderstorms, meteorites, or
earthquakes. They also travel a great distance, bouncing between the earth’s surface and the
ionosphere and overlying magnetosphere. Their spectra are much more dispersed than Sferics or
Tweeks and they interact with plasma particles in the radiation belts. Dawn Chorus is generated near
the magnetic equator outside the plasmasphere and occurs over a broad frequency range, peaking near
local dawn. It interacts with high-energy electrons in the radiation belts and accelerates them to near
light speed during geomagnetic storms. These high-energy electrons are dangerous for both satellites
and astronauts.  Hiss occurs when the high-energy electrons associated with Dawn Chorus are
deflected into the upper atmosphere, where they lose energy in interactions with atoms and larger
molecules. More info at
