Noise pollution TED talk - APES

What is one of the physical challenges the speaker describes facing while working in the Arctic waters?

• Dealing with aggressive marine mammals.

• Her drysuit being too big, allowing cold water in.

• Navigating through dense ice formations.

• Lack of proper equipment for tagging.

What is the primary concern the speaker highlights regarding increased human activity in the Arctic?

• The melting of sea ice.

• The pollution of the environment with waste.

• The increase in underwater noise.

• The overfishing of marine species.

For what purposes do beluga and narwhal whales use sound in their natural environment?

• To attract mates and warn off predators.

• To navigate through ice and find food.

• To communicate, locate food, and find breathing holes.

• To echolocate and stun their prey.

Why were narwhal calves unable to reach open water during the ice entrapment?

• They were too large to navigate the narrow ice channels.

• Their mothers prevented them from leaving the group.

• They lacked the necessary lung capacity for the long journey.

• The distance to open water was too great for their swimming speed.

What did scientists propose as the reason for narwhals returning to their ice-covered summer grounds during migration?

• Unforeseen changes in ocean currents.

• Seismic activity interrupting their traditional migration path.

• A sudden drop in water temperature.

• The presence of new predators in their wintering areas.

How does the noise generated by seismic ship-based surveys primarily impact narwhals?

• It causes them to become disoriented and swim in circles.

• It masks their communication, hinders their ability to find food, and locate breathing holes.

• It leads to a decrease in their reproductive rates due to stress.

• It forces them to migrate to warmer waters, disrupting their natural habitat.

What significant action did Inuit hunters take in 2010 regarding seismic testing in Lancaster Sound?

• They launched a public awareness campaign about noise pollution.

• They secured an injunction to halt seismic testing in the area.

• They proposed new regulations for quieter shipping routes.

• They collaborated with researchers to monitor narwhal populations.
