Noise pollution affects sea turtle behavior because turtles can hear between 100-800 frequencies. This is within the range of human voice, so the turtle species can hear us! And because sound travels faster in water than in air, the impact of noise pollution on sea turtles is almost immediate. Noise pollution comes from man-made sound sources, such as airguns from seismic surveys, drilling and fracking from oil and gas production, motor engines from boats and wind farms, cars from traffic, and even human conversations. Therefore, volunteers are conducting acoustic research with sound meters and hydrophones (underwater microphones) to assess the potential human impact on sea turtle basking behavior.
