Noise Pollution:

Dolphins use sound, or echolocation, to communicate and navigate in the waters. Noise pollution affects how dolphins communicate and can make them feel scared.

  • Loud underwater seismic searches or surveys (pulses of noise sent down to the seabed) to locate oil and gas

  • Military exercises using powerful underwater sonar

  • Increasing levels of boat activity

Water Polution:

Sources of toxins that harm dolphins include

  • Sewage

  • Industrial dumping

  • Polluted runoff water

Chemical spills, seismic noise used to find oil and gas, conducting loud military exercises at sea and increases in boat traffic can all put whales and dolphins in danger, cause them to strand on coastlines, and even kill them.
