The utility of ShoreZone maps for change detection was assessed by independent reviewers in 2009 and 2011, and findings include: 1) the NOAA Coast63 digital shoreline used by ShoreZone in Alaska poorly resolves features less than 50 meters, i.e., many small scale features are not represented and thus cannot be accurately described; 2) ShoreZone ...

Isostatic change could be due to post-glacial adjustment. [2] Another common cause of isostatic change that can result in a submergent coastline is tectonic action. [2] Events such as earthquakes or volcanic eruptions may cause land subsidence therefore causing isostatic sea level increases. [2] Eustatic sea level rise can also be caused by ...
