As struggles over land rights, beach access, and local autonomy in Mo’orea continue to intensify, the 2026 UC Berkeley Island Sustainability Program (ISP) class collected coastal armoring data on the northwest and southern coasts of the island. Coastal armoring, especially the establishment of sea walls, disturb ocean currents, eroding shorelines and harming fragile marine ecosystems. Under Jean Wencelius, the 2026 UC Berkeley ISP class stratified coastal armoring categories as the following: ArmRocks (armored with rocks), ArmVegetation (armored with overhanging vegetation), UnArmored (no visible artificial armoring), ArmSeaWall (armored with walls of a variety of materials), perpendicular protrusions (docks, rock structures, etc.). These observational data were collected on-site in kayaks on March 5 and March 10, 2026 and calibrated with timestamped Gaia navigation data to map observations onto specific coastline coordinates.
