List of citizen science projects

Citizen science projects are activities sponsored by a wide variety of organizations so non-scientists can meaningfully contribute to scientific research. Activities vary widely from transcribing old ship logbooks to digitize the data as part of the Old Weather project to observing and counting birds at home or in the field for eBird.[1][2] Participation can be as simple as playing a computer game that may help scientists learn more about retinal neurons for a project called Eyewire.[3] It can also be more in depth, such as when citizens collect water quality data over time to assess the health of local waters, or help discover and name new species of insect.[4][5] An emerging branch of Citizen Science are Community Mapping projects that utilize smartphone and tablet technology. For example, TurtleSAT[6] is a community mapping project that is mapping freshwater turtle deaths throughout Australia.

This list of citizen science projects involves projects that engage all age groups. There's projects specifically aimed at the younger age demographic like iTechExplorers[7] which was created by a 14 year old in the UK to assess the effects of bedtime technology on the body's circadian rhythm and can be completed in a classroom setting. Other projects like AgeGuess[8] focus on the senior demographics and enable the elderly to upload photos of themselves so the public can guess their ages.

Lists of citizen science projects may change. For example, the Old Weather project website indicates that as of January 10, 2015, 51% of the logs were completed.[9] When that project reaches 100 percent, it will move to the completed list.

There are more than 3,000 active and searchable global citizen science projects listed on the SciStarter website.[10]

Notes

1. CosmoQuest is sponsored by NASA in partnership with the Astrosphere New Media Association, the STEM Center, UniverseToday, Astronomers without Borders, the Planetary Society, the Ward Beecher Planetarium, the Galileo Teachers Training Program, Swinburne Astronomy Online, Dark Skies, Bright Kids, the Canadian Astronomy Data Centre and its member organizations, the Galileoscope Project and several NASA projects.
2. BirdSleuth is primarily for students from kindergarten through middle school.
3. Formerly The Birdhouse Network which only monitored nests in bird boxes and similar artificial cavities. NestWatch is a new project that collects observations of open nests as well.
4. Per the project website, this project was absorbed into the current FeederWatch project.
5. Formerly Ice Hunters, a project to identify potential targets in the Kuiper belt for the New Horizons spacecraft after it completes its mission to Pluto.
6. Over a million craters were identified and mapped in late 2012. As of March 2012, 1,207,486 craters have been identified and mapped by the Moon Mappers parent project that continues.
