"From the Ted Talk by Stephanie Sardelis: Why do whales sing?"

Unscramble the Blue Letters

We can eavesdrop on these songs using underwater microphones called hydrophones. These help us track sicepes when sightings or genetic samples are rare. For example, scientists have been able to differentiate the elusive blue whale's populations worldwide based on their sgons. But the oceans are getting noisier as a result of human aivtitcy. Boating, maiilrty sonar, underwater construction, and seismic surveys for oil are occurring more often which may interfere with whale's communication. Some whales will avoid key feeding or breeding grounds if human noise is too loud. And humpback whales have been observed to reduce their sgining in response to noise 200 komlitrees away. Limiting human activity along migratory routes and in other critical htaaibts, and reducing nosie pollution throughout the ocean would help eursne whales continued survival. If the whales can keep singing and we can keep lsniinetg, maybe one day we'll truly uersntdand what they're saying.

Original Text

We can eavesdrop on these songs using underwater microphones called hydrophones. These help us track species when sightings or genetic samples are rare. For example, scientists have been able to differentiate the elusive blue whale's populations worldwide based on their songs. But the oceans are getting noisier as a result of human activity. Boating, military sonar, underwater construction, and seismic surveys for oil are occurring more often which may interfere with whale's communication. Some whales will avoid key feeding or breeding grounds if human noise is too loud. And humpback whales have been observed to reduce their singing in response to noise 200 kilometers away. Limiting human activity along migratory routes and in other critical habitats, and reducing noise pollution throughout the ocean would help ensure whales continued survival. If the whales can keep singing and we can keep listening, maybe one day we'll truly understand what they're saying.
