PALAOA , the Perennial Acoustic Observatory in the Antarctic Ocean , listens to the water below Antarctica for the sounds of whales and other marine mammal amidst a soundscape of constantly shifting ice . Here ’s what they ’re get wind right now .
PALAOA’sLivestream pagehas links to the audio stream in both MP3 and OGG - Vorbis .
If you ’re ask to tune in and instantly hear resplendent , quartz glass - clear whale song , you might be let down . As the pageboy excuse :
Please note , this infection is not optimize for easy listening , but for scientific research . It is extremely compressed … so good quality is far from perfect . Additionally , fauna voices may be very faint . Amplifier configurations are a via media between picking up remote animals and not overdriving the system by nearby calving icebergs … A constant hiss pervading the signal is partly due to electronic stochasticity as we bear on the hydrophone amplifiers to their boundary , but also the natural ocean background noise made audible here through the use of extremist sensitive hydrophones . Additional broad band noise due to wind , waves and current adds to it on function . There a three sources of click - like hindrance : switch relais , electrostatic release stimulate by snow drift , and sferics bring on by thunderstorm ten chiliad of kilometers away .
Still , the idea is undeniably cool and there is some telling engineering science that makes it all go on .
Two hydrophones capture the subaquatic audio outside a nothingness and solar power observation tower on the Ekström water ice shelf . The data is transmitted wirelessly to another base in Germany and then send to listeners worldwide via artificial satellite .
If you ’re seem for some ambient haphazardness to mind to while you do some work or impetus to sleep , it ’s hard to think of anything more astonishing than this . [ PALOAO ]
