Scientists and marine biologists(海洋生物学家) had something to celebrate last week when two lost humpback whales(座头鲸) returned to the Pacific Ocean. Delta and Dawn — a mother and a baby — had circled the Sacramento Bay area for two weeks before going back to the ocean.
"We all shouted loudly like 'Yay'!" said Jim Oswald, a spokesman for the Marine Mammal Center. "It's been really exciting."
The humpback whales were last spotted on May 29 near the Golden Gate Bridge in San Francisco, California. Scientists are sure that the whales swam into open water during the evening of May 29 or early the next morning, since there have been no further sightings of the whales. Even so, boats were sent out to look for them, just in case the whales made another wrong turn.
Officials spent two weeks trying to get the whales to turn back towards the ocean. Biologists played recordings of whale-feeding as well as unfamiliar sounds to try to make the whales head back to the Pacific Ocean.
However, Delta and Dawn gave scientists an unexpected chance to study humpback whales in the wild. Scientists were able to gather sound recordings and watch their behaviors. This is especially exciting because humpback whales are an endangered species. What's more, scientists don't usually have the chance to observe (观察) them in their natural habitat.
"All those things are very hard to get," said Oswald," So what we are doing is filling up the knowledge blank on humpback whales in the wild." Scientists should be able to use this information to help other lost whales in the future.
