Pond Station


Pond Station is a modular platform for monitoring the hidden activity of a freshwater pond. It has been transmitting since May 2015 when it was commissioned as a long-term sculpture at Wave Farm in Acra, NY.

Pond Station floats on the water’s surface, broadcasting underwater sounds through a live radio link. It operates from dawn to evening every day, using solar-charged internal batteries. Pond Station’s receiver is located in the Wave Farm radio studio where resident artists and broadcasters on WGXC FM can experience the pond’s natural sounds or remix and interpret them. International audiences are invited to do the same via the live web stream below.

PondStation-DSLR-sunny-close-widePond Station made its first broadcast on May 2, 2015 during REVEIL, a 24hr live broadcast of the sounds of daybreak from all over the world organized by Maria Papadomanolaki and Grant Smith.

At sunrise, Pond Station’s hydrophones (underwater microphones) reveal a photosynthetic chorus of bubbling as plants begin to produce oxygen. Insect, fish and frog vocalizations continue all day, combined with the traces of sounds in the air that excite the water too (like passing cars, singing insects or humans). Rain on the pond surface creates a dense cloud of high-frequency detail, like the coals in a cooling campfire. In the winter, life in the pond slows down to near silence as the water ices over, but the ice may crackle and hiss during its daily expansion and contraction.

Live Audio Stream

Sorry, Pond Station is offline for seasonal upgrades. Tune in again in Spring 2017!

67° F

(Stereo MP3 format, active from dawn to dusk in the Eastern US)

You can record the stream with VLC. I wrote a guide to help you.

Archived Sounds

May 2015: Early morning. Rhythmic sounds stop after a car passes, then restart with a different tempo.

May 2015: A cloudy morning. Loud repeating croaking sounds dominate the soundscape.

May 2015: Light rain creates random noise, partially masking the smaller repeating sounds.

June 2015: Night on the pond. Very quiet except for the frogs.



Pond Station’s physical form is inspired by the utilitarian beauty of remote research stations and space probes. Its exterior is designed to withstand high winds and rain while keeping its electronics dry and its antenna focused on the receiver. The project began in 2013 as Pond FM (with N.B.Aldrich), an installation that transmitted the underwater sounds of the pond over short-range FM radio. Pond Station is based on the same custom hydrophones but the rest of the system has been replaced with a more rugged and upgradable platform. The audio is transmitted over a low-power digital radio link using custom-built antennas to cover the 350ft distance between the pond and the receiver. An Arduino microcontroller manages the transmission schedule and power distribution to keep the station on the air regardless of weather. A telemetry radio transmits updates about the internal electronics and local environmental data, which are archived for future analysis. (The environmental data also helps contextualize the sounds since sunlight is the primary driver of the pond’s ecosystem.) The web stream is powered by a Raspberry Pi and the Locus Sonus streaming server and sound map.

In 2016 Pond Station was upgraded to include light-based sensors which reveal some of the insect “night life” of the pond and provide opportunities for light-based interaction with performers.

March 2016

  • Added night-time lighting and light-sensitive components
  • Upgraded preamps to reduce noise and improve dynamic range compression
  • Upgraded flotation so it wouldn’t sink!

September 2015

  • Changed audio transmitter/receiver to 5.8gHz analog technology to alleviate digital noise in the power supply
  • Added dynamic range compressor to reduce distortion on loud events

May 2015

  • Initial launch
