Wildlife Acoustics at sea, land…and now sky with BBC Cloud Lab expedition!

Wildlife Acoustics at sea, land…and now sky with BBC Cloud Lab expedition!

Not too long ago, we announced that the revolutionary solar-powered research ship, MS Tûranor PlanetSolar had embarked from Boston on its DeepWater Expedition along the Gulf Stream with a Wildlife Acoustics SM2+ bioacoustics recorder and hydrophone in tow.

Now, we are taking it to the skies with the amazing BBC Cloud Lab airship expedition. Starting off from Cape Canaveral and ending in San Francisco, the month-long trip will take a group of scientists over oceans, wetlands, drylands, and deserts. Bat researcher, Jennifer Krauel will be using Wildlife Acoustics SM2BAT+ to study bats and high-flying insects. Jennifer KrauelThe BBC2 crew will film her studies while the ship is above Frio cave in Texas, which is expected to be around the end of October. In a recent blog post, Krauel explains in detail how she tested the device on the airship using various microphone cables and fishing weights. In addition to recording bat passes, Krauel has also installed an insect net outside the ship to collect insect samples. The net has a pouch in the back so that scientists will be able to remove and collect insect samples throughout the trip.

Be sure to stay tuned for updates on the expedition!

Spotlight on optional hardware attachments: The SMX-UT ultrasonic microphone

Looking to upgrade your bat recording rig? The SMX-UT is our most powerful and precise tool for omnidirectional bat recording.

As the higher end alternative to our SMX-US ultrasonic microphone, the SMX-UT provides a flatter frequency response and higher sensitivity at frequencies above 60kHz. It records up to 192kHz and it’s weatherproof, just like the standard SMX-US microphone. The SMX-UT has very little reduction in sensitivity off-axis, which means it can record bats in all directions. This is helpful for capturing a larger sampling of bat passes and echolocations.

And if your recording needs require a directional microphone, the SMX-UT is compatible with our SMX Horn accessory. This horn will transform the UT microphone into a highly directional microphone.
