Hold the Line: A Registry for Vanishing Coastlines
A proposed satellite-based registry that helps Pacific island nations preserve evidence of changing maritime baselines.
Field notes
The proposed registry combines free satellite imagery with tide data, compares readings against official coordinates, and is described as checking whether coastal features remain above water at high tide. The page says a new measurement would be added every five days, creating a record for possible future boundary disputes. Its examples focus on Tuvalu and Kiribati, including Tuvalu's stated A$39.0 million in annual fishing-licence revenue and Kiribati's 3.4 million km² ocean territory.
