Overview

An Interactive Mapping Tool to Assess Future Sea Level Rise Scenarios.

Since the earthquake doublet that generated the devastating Samoan tsunami in September 2009, American Samoa continues to experience accelerated rates of sea level rise due to land subsidence, or sinking of land. The American Samoa Sea Level Rise Viewer (Viewer) is an interactive tool developed to allow stakeholders to assess local vulnerability to sea level rise. The Viewer provides maps of flooding extent for various combinations of:

• Sea level rise scenario with the ability to select specific future years
• One-foot increments of sea level rise
• Frequency of flooding

The project was developed by the Pacific Islands Ocean Observing System (PacIOOS) at the University of Hawaiʻi at Mānoa (UH) School of Ocean and Earth Science and Technology (SOEST) and the Department of Oceanography at UH SOEST in partnership with the University of Hawaiʻi Sea Grant College Program, also within UH SOEST. The Viewer was funded by the Pacific Islands Climate Adaptation Science Center (PI-CASC).
