=== Rocky reefs ===
Reef Life Survey is a marine life monitoring programme based in Hobart, Tasmania. The project uses recreational divers that have been trained to make fish and invertebrate counts, using an approximate 50 m constant depth transect of tropical and temperate reefs, which might include coral reefs. Reef Life Survey is international in its scope, but the data collectors are predominantly from Australia. The database is available to marine ecology researchers, and is used by several marine protected area managements in Australia, New Zealand, American Samoa and the eastern Pacific. Its results have also been included in the Australian Ocean DATA Network.

=== Agriculture ===
Farmer participation in experiments has a long tradition in agricultural science. There are many opportunities for citizen engagement in different parts of food systems. Citizen science is actively used for crop variety selection for climate adaptation, involving thousands of farmers. Citizen science has also played a role in furthering sustainable agriculture.

=== Art history ===
Citizen science has a long tradition in natural science. Today, citizen science projects can also be found in various fields of science like art history. For example, the Zooniverse project AnnoTate is a transcription tool developed to enable volunteers to read and transcribe the personal papers of British-born and émigré artists. The papers are drawn from the Tate Archive. Another example of citizen science in art history is ARTigo. ARTigo collects semantic data on artworks from the footprints left by players of games featuring artwork images. From these footprints, ARTigo automatically builds a semantic search engine for artworks.

=== Biodiversity ===

Citizen science has made significant contributions to the analysis of biodiversity across the world. A majority of data collected has been focused primarily on species occurrence, abundance and phenology, with birds being primarily the most popular group observed. There is growing efforts to expand the use of citizen science across other fields. Past data on biodiversity has had limitations in the quantity of data to make any meaningful broad connections to losses in biodiversity. Recruiting citizens already out in the field opens a tremendous amount of new data. For example, thousands of farmers reporting the changes in biodiversity in their farms over many years has provided a large amount of relevant data concerning the effect of different farming methods on biodiversity. Another example is WomSAT, a citizen science project that collects data on wombat roadkill and sarcoptic mange incidence and distribution, to support conservation efforts for the species.
Citizen science can be used to great effect in addition to the usual scientific methods in biodiversity monitoring. The typical active method of species detection is able to collect data on the broad biodiversity of areas while citizen science approaches has shown to be more effective at identifying invasive species. In combination, this provides an effective strategy of monitoring the changes in biodiversity of ecosystems.

=== Health and welfare ===

In the research fields of health and welfare, citizen science is often discussed in other terms, such as "public involvement", "user engagement", or "community member involvement". However the meaning is similar to citizen science, with the exception that citizens are not often involved in collecting data but more often involved in prioritisation of research ideas and improving methodology, e.g. survey questions. In the last decades, researchers and funders have gained awareness of the benefits from involving citizens in the research work, but the involvement of citizens in a meaningful way is not a common practice. There is an ongoing discussion on how to evaluate citizen science in health and welfare research.
One aspect to consider in citizen science in health and welfare, that stands out compared to in other academic fields, is who to involve. When research concerns human experiences, representation of a group becomes important. While it is commonly acknowledged that the people involved need to have lived experience of the concerned topic, representation is still an issue, and researchers are debating whether this is a useful concept in citizen science.
Outside of the older patient and public involvement tradition, there are also efforts to bring the newer citizen science efforts to health and biomedical research. These efforts cover a broad spectrum of involvement and co-leadership of patients, including patient-led research, quantified self or personal science, as well as collaborative research efforts between researchers and patient-groups, often enabled by digital technology. A survey among European practitioners involved in health-related citizen science found that ethical challenges and achieving a balanced return on investment for patients and medical staff are common challenges.

== Modern technology ==
Newer technologies have increased the options for citizen science. Citizen scientists can build and operate their own instruments to gather data for their own experiments or as part of a larger project. Examples include amateur radio, amateur astronomy, Six Sigma Projects, and Maker activities. Scientist Joshua Pearce has advocated for the creation of open-source hardware based scientific equipment that both citizen scientists and professional scientists, which can be replicated by digital manufacturing techniques such as 3D printing. Multiple studies have shown this approach radically reduces scientific equipment costs. Examples of this approach include water testing, nitrate and other environmental testing, basic biology and optics. Groups such as Public Lab, which is a community where citizen scientists can learn how to investigate environmental concerns using inexpensive DIY techniques, embody this approach.
