Zooniverse Citizen Science Projects
The Zooniverse is a collection of web-based Citizen Science projects that use the efforts and abilities of volunteers to help researchers deal with the flood of data that confronts them. Review or transcribe data from centuries-old logs of whaling ships, listen to bat calls, identify marine invertebrates, or watch a red hawk nest to learn more about their calls and behavior. There are dozens of projects available in a variety of disciplines. To volunteer, just go to the Projects page, choose one you like the look of, and get started.
