397961 - Incorporation of Low Cost Environmental Sensors into Water Resources Education: The Challenge of Data Quality

Location: Skyway Room

As low-cost electronics have become increasingly accessible to non-experts, it has become relatively straightforward to design, construct, and deploy projects that collect, log, and disseminate environmental data. For example, there are numerous online resources that guide non-experts through automated collection of weather data, water level and discharge, water quality, soil moisture content, and more, using open-access development tools such as Arduino or MicroPython and low-cost, readily available components. The ability to collect and share data that may be of questionable quality raises important questions about the usefulness of the data and the scientific value of such projects. A review of water-related projects performed in the context of K-12 education, university-level coursework (including a recently developed undergraduate course at Seattle University), and citizen-science initiatives is provided. In general, the following principles can be adapted to citizen-led data collection/dissemination efforts: 1) Develop and publish with the data a clear statement of the project purpose and/or the research question (ideally including a scientific hypothesis); 2) Develop and publish/post data validation exercises that provide simple, independent data checks; 3) Ensure that adequate time is provided for troubleshooting field installations and for collecting data across representative space and time intervals; 4) Address and discuss the primary sources of error associated with the system—particularly those that may result from variability in temperature or supply voltage; and 5) Develop approaches for cursory peer review. Because these principles are already an important part of the scientific method, adhering to them as part of citizen science projects has the potential to broaden the participation of non-experts in the scientific process.
