underwater markers

The Underwater Markers are yard signs that announce a home’s elevation above sea level in an effort to catalyze conversation and action around the climate crisis. Participants of The Underwater are encouraged to discover the elevation of their home and paint or draw that number on their blank yard sign (pictured above).

Once residents place these elevation-marked signs in their front yard, curiosity from neighbors, friends, and family is instantly sparked as the meaning of the number is unknown to anyone not familiar with the project. It’s precisely in these moments of intrigue when project participants have the opportunity to educate the individual(s) about the local impacts of sea level rise and motivate them to get involved in efforts to protect Miami.

The backdrop of the Underwater Marker is an “ice painting” that artist Xavier Cortada created using melted Antarctic ice during his trip to the world’s southernmost continent in 2007. Cortada, recipient of a 2006-2007 National Science Foundation Antarctic Artists and Writers fellowship, traveled to Antarctica to create new works and implement a series of projects and installations.
