Thousands of people help scientists with research on endangered Steller sea lion

Steller Watch project a huge success but still more work to be done!

As of the end of August, over four months after our launch, over 6,500 people have participated in Steller Watch helping us classify over 130,000 images. The ultimate goal -- to figure out why the endangered Steller sea lion continues to decline in the western Aleutian Islands.

After a short break while we were in the field collecting more photographs and other data on Steller sea lions, Steller Watch is live again.

With the help of the private citizens we are almost halfway through the newest set of images.

“The work of citizen scientists has been invaluable,” said Katie Sweeney, biologist, NOAA Fisheries, Alaska Fisheries Science Center. “They help us classify images and regularly participate in our talk forums on the project site. Members of the public can even nominate a sea lion of the month, which is then featured in a story on our project blog.”

“We’re still looking for more help though as there are lots of photos to go through.” Check out Steller Watch.
