Overview

This new tool hosted within NOAA’s Digital Coast platform, the Sea Level Calculator, provides easy access to the best available data for any chosen location. 

In addition to the raw data, users can explore how sea levels and coastal flooding have changed in frequency and magnitude over time and get access to information about future flooding served up in easy-to-understand charts and maps. 

The Sea Level Calculator uses Quick Views to present curated sets of data and interactive visualizations that focus on different dimensions of coastal inundation and sea level rise:

• Future Sea Levels
• Changes in Flood Frequency
• Extreme Water Levels
• Observed Sea Level Trends
• Seasonal Variation

After entering a location on the tool homepage, users can select a tide station. The number of Quick Views depends on the data available for that tide station. When choosing a tide station, consider the proximity and similarity to your area of interest and the available Quick Views at each station. Alternatively, you can select anywhere on the map if you only want to access sea level rise scenarios for that location.

This Calculator complements the content on the interagency sea level science platform, sealevel.globalchange.gov, which was launched by Interagency Task Force on Sea Level Change (DOD, DHS, EPA, NASA, NOAA, USACE, USAID, and USGS). The Calculator provides additional historical and seasonal data, as well as geospatial mapping functionality and the ability to set user-defined thresholds and customize datums, units, and vertical land motion rates.
