Less ice means fewer calling seals, finds study

When the sea ice vanishes, Antarctic seals become silent. This is the main conclusion of a new article just published by Dr. Ilse van Opzeeland's research group in the journal Frontiers in Ecology and the Environment. The ...

Seismic imaging provides insight into the Earth's subsurface

The seismic reflection method involves sending acoustic waves thousands of meters under the Earth's surface. The reflected signals provide scientists with information about the characteristics of the subsurface. This is how ...

Acoustic sensors to pinpoint shooters in an urban setting

During a gunshot, two sound events occur: the muzzle blast and the supersonic shock wave. Acoustic sensors, such as arrays of microphones, can capture these sounds and use them to approximate the location of a shooter.
