Detailed Description

Fire Island shorelines from 1985 to 2018 were extracted from imagery and are plotted together with 2018 imagery to reveal how a breach in the island has evolved through time. From 1985-2011, the island was continuous at this location. The passage of Hurricane Sandy in 2012 formed a breach in the middle of the island and this breach can be observed in 2018 imagery and shorelines from 2013-2018.
