King Tides is an initiative to document extreme high tides and share the information, in preparation for global sea level rise.
The King Tides Project can help people all over the world understand how sea level rise will impact their lives. Extreme high tides, or “king tides”, occur at a few specific times during the year when the moon is closest to the Earth. During these high water events, we can see what the average water levels might look like in the future, given projected sea level rise. The King Tides Project invites people to visit the shoreline and capture images of important places threatened by sea level rise.
The current website is the hub connecting King Tides Project participants and organizers around the world. In Spring 2014, King Tides partners are building a platform for researchers, planners, communicators, and the public to share images of coastal flooding.
Currently, King Tides images are used by NOAA Coastal Services Center’s Sea Level Rise Viewer; the Our Coast, Our Future decision support tool; by the California Natural Resources Agency; and by numerous other agencies; non-profits; and community organizations around the world.
King Tides photos are used several ways to help people:
1. Document current flood risk in coastal areas
2. Visualize the impacts of future sea level rise in their community
3. Ground-truth and validate climate change models by comparing model predictions with the high-tide reality
4. Serve as a living record of change for future generations
Photos may be used in presentations, exhibitions, websites and publications on sea level rise impacts, coastal initiatives and climate action. Photos may also be used by government agencies for research and planning to assess where coastline is most vulnerable, and by scientists to better predict future sea level rise.
