Spring in the Arctic Means Polar Bear Cubs
... and PBI field researchers. Data from our ongoing Maternal Den Study and Den Acoustics Study will help set guidelines to protect denning polar bear mothers with cubs from industrial disturbances.
We've already established the polar bear's hearing range. Now we're looking into such questions as:
- What industrial noises travel through snow dens?
- From what distances do the sounds travel?
- When do denning families typically emerge and how sensitive are they to disturbances?
