Trevor Hebert-Jasper Ridge Biological Preserve live audio stream


Jasper Ridge Biological Preserve

Latitude: +37.404001°
Longitude: -122.228781°

The microphone is located adjacent to lake, woodland and wetland habitats, capturing the sounds of a diverse range of birds, amphibians and insects. Jasper Ridge is near Stanford University's campus in the eastern foothills of the Santa Cruz Mountains.
The microphone site is adjacent to lake, woodland and wetland habitats. The audio streaming setup consists of an outdoor electret microphone with a low noise MOSFET pre-amplifier. A Barix Instreamer analog-to-digital encoder, sampling at 32 KHz, streams MPEG-1, audio layer III (MP3) over internet protocol (IP) to Locus Sonus. The Instreamer uplinks to the internet via a dual-radio A/N wireless access point, part of the Preserve's outdoor wireless mesh network. Solar panels and sealed gel batteries currently provide power.

Jasper Ridge Biological Preserve (JRBP) is located near Stanford University's campus in the eastern foothills of the Santa Cruz Mountains. The preserve encompasses remarkable geologic, topographic, and biotic diversity within its 483 hectares (1193 acres) and provides a natural laboratory for researchers from all over the world, educational experiences to students and docent-led visitors, and refuge to native plants and animals.

The careful management of the preserve's ecosystems in as natural a state as possible allows scientists to quantify changes observed in similar ecosystems affected by a range of human impacts. In addition to facilitating first-rate research, this highly accessible field station provides undergraduate educational experiences and plays an active role in educating the general public.

What you may hear
A couple of the most distinctive (and asked about) sounds are those of the pied-billed grebe ("jungle soundtrack bird") and the American bullfrog (repetitive groan/moan). This time of year red-winged blackbirds often dominate the chorus. Bewick's wren and Common yellowthroats are also typically heard. Listen for the occasional wild turkey and belted kingfisher.
At least one mountain lion has been heard "caterwauling" on this stream.
