A website called Orcasound lets you listen to orcas using hydrophones, which are underwater microphones. Scientists use these recordings to find and study whales, especially at night or in bad weather.
The team behind Orcasound hope that non-expert listeners will help quickly alert researchers to the presence of orcas, so they can send out boats to test fecal matter and leftover bits of prey, thereby getting a better sense of what the whales are eating.
If you like whales and you’re interested in citizen science, check out Orcasound.
