The BeringWatch Sentinel app is for trained community-based observers and local and traditional knowledge holders to record ecological and environmental observations in their local communities.

The BeringWatch Sentinel Community-Based Monitoring Network which includes the Sentinel app was designed and refined over the past 15 years in Alaskan Native communities. Users of the BeringWatch Sentinel app are located primarily in remote communities that are affected by a rapidly changing environment. The strength of the BeringWatch environmental data collection framework is that it is tribally-driven. Communities are better able to actively participate and lead data collection that both addresses community concerns and contributes meaningful scientific data to researchers, resource managers, and decision makers.
