Nicola Jones: The dangers of a noisy ocean -- and how we can quiet it down

The video discusses the impact of noise pollution on marine life, highlighting how human activities like shipping, seismic surveys, and drilling contribute to increased ocean noise. It explains the effects of acute and chronic noise on marine species, such as stress and physical harm, and compares these effects to human experiences with noise. The video also explores solutions to mitigate ocean noise, including policy changes and technological innovations, and presents a case study on the positive impact of silence during Bali's Nyepi Day.

What is one of the primary reasons orcas make sounds?

• To scare away predators

• To create music

• To communicate and echolocate

• To attract tourists

Which human activity is known for producing loud blasts in the ocean?

• Fishing

• Seismic surveys

• Underwater photography

• Recreational boating

How does chronic noise affect some marine animals?

• It increases their size

• It makes them more aggressive

• It causes them to change their communication patterns

• It improves their hunting skills

What was a significant observation after the 9/11 attacks regarding marine life?

• Increased whale strandings

• Increased ocean temperatures

• Reduced stress markers in whales

• More fish caught by fishermen

What is a simple method to reduce noise from ships?

• Using more fuel

• Increasing their size

• Slowing them down

• Painting them a different color

What incentive did the Vancouver Fraser Port Authority introduce for quieter ships?

• Free fuel

• Extended travel routes

• Discounts on docking fees

• Priority docking

What is the relationship between ship efficiency and noise levels?

• Efficiency has no impact on noise

• More efficient ships are quieter

• More efficient ships are louder

• Less efficient ships are quieter

What is the Nyepi Day of Silence?

• A day dedicated to whale watching

• A festival celebrating loud music

• A Hindu tradition where noise is minimized

• A day when all marine activities are increased

What was the impact of Nyepi Day on ocean noise levels?

• Noise levels were not measured

• Noise levels increased

• Noise levels remained the same

• Noise levels dropped significantly

What is the potential benefit of reduced ocean noise for marine life?

• Increased predator presence

• Decreased food availability

• Improved communication and mating opportunities

• Increased stress levels
