a local beach and regularly takes a series of measurements and tests of their beach using simple and readily available equipment. By measuring how the beach's width, currents, waves, water quality and other factors change over months and years, the teams can determine whether their beach is stable and healthy or stressed and deteriorating, and the nature of the stressors. When a group identifies a problem it can, with the community, develop a project to address and mitigate the problem or problems. Project activities include alerting authorities to potential problems such as water contamination (from sewage or agricultural runoff for example), conducting beach clean-ups, replanting mangroves or dune stabilization vegetation, creating signage for proper beach use, monitoring and protecting marine turtle nesting sites, or monitoring the effects of coral bleaching. By keeping the beach and related ecosystems healthy they are made more resilient and better able to adapt to climate change. All Sandwatch groups are encouraged to regularly post their data, photographs and other project details on the Sandwatch website, as well as to contribute articles and photographs to the twice-yearly newsletter, The Sandwatcher. Sandwatch representatives are often invited to participate in regional and international workshops and conferences, where they share their experiences and data and forge partnerships with similar environmental groups.
