What is the King Tides Project?

  • The King Tides Project is an international initiative to document extreme high tide events using photos
  • These photos can help us visualize how “normal” high tides could look in the future due to sea-level rise
  • From these images we can create a record of how our shoreline looks today and track future changes.
  • By visualizing these higher tide events we can start to understand how rising sea-levels will impact local resources and community investments

What are king tides?

  • King tides are the highest high and lowest low tide events of the year
  • They are regular and predictable events that occur when the Sun, Earth, and Moon are in alignment and the Moon is at its closest point to the Earth
  • These condition cause extreme highs and lows during the daily tidal cycle

North Carolina is interesting because…

  • For  many of us living in coastal North Carolina, flooding is a normal part of life.
  • The coast here is very flat, and tides, heavy rain events, and even wind play an important role in determining water levels
  • We are not only asking for photos of tidal-related events, but also encourage participants to share photos of any flooding or high water events they observe
