DESCRIPTION:*Talk Abstract*\n\nOur planet naturally produces a variety of 
 radio emissions\, generated by lightning activity and geomagnetic storms d
 riven by the Sun. These natural radio waves are at the lower end of the ra
 dio spectrum in the audio-frequency range\, so-called because they have th
 e same frequencies as audible sound waves. We use a Very Low Frequency Rec
 eiver\, located at Halley Research Station in Antarctica\, to record these
  emissions. Halley is a great location to detect these waves because it is
  magnetically connected to the outer radiation belt where some of the sign
 als are generated and is electromagnetically “quiet”\, being far from 
 man-made sources. At the British Antarctic Survey\, we use this radio wave
  data primarily to investigate the science of space weather storms\, to he
 lp us understand the impact of space weather on the Earth-Climate system\,
  and for lightning detection. As a remarkable spin-off\, conversion to sou
 nd reveals a series of weird and wonderful noises\, known as the ‘sounds
  of space’. In this presentation\, we will explore the amazing variety o
 f natural ‘sounds’ detected at Halley\, Antarctica and then embark on 
 a sound-led\, data-driven journey from Earth-orbit to beyond the galaxy! I
  will then describe how the “Sounds of Space Project”\, our art-scienc
 e collaboration\, has woven these mysterious “sounds” into performance
 s that fuse art and science\, new music\, and short films. I will introduc
 e our first album\, “Aurora Musicalis”\, which features recordings fro
 m the Halley VLF Receiver accompanied by ambient music on a grand piano. M
 y talk will culminate with a presentation of the tracks and track artwork 
 from “Celestial Incantations”\, our second album\, which features the 
 ‘sounds of space’ from astronomical objects both within and beyond our
  solar system together with a massive musical palette\, including orchestr
 al and traditional instruments and electronics.\n\nFurther Information\n\n

  \n\n---\n\n*Speaker Information*\n\nDr Nigel Meredith is a space weather 
 research scientist at British Antarctic Survey. He uses satellite data to 
 develop global models of plasma waves in near Earth space for input into r
 adiation belt codes and\, ultimately\, to forecast space weather. He is al
 so interested in extreme space weather and has recently applied extreme va
 lue analysis to long-term satellite datasets to determine the 1 in 10\, 1 
 in 50 and 1 in 100 year space weather events. This is important for assess
 ing the impact of extreme events on the world’s satellite fleet. He enjo
 ys exploring how to make scientific data more accessible and is currently 
 involved in an art-science collaboration\, ‘sounds of space’. He has p
 ublished 128 papers in peer-reviewed journals covering a wide range of top
 ics in space plasma physics.
