In Extremis is a multimedia installation by Claudia O’Steen that examines the effects of climate change and human impact on the South Carolina coastline and the ways in which the eroding salt marshes impact the surrounding landscape to create ghost forests. As marshes erode, salt water encroaches on the maritime forests, slowly killing living trees and turning them into decaying lumber.

This work is the search for a transitional landscape and methods to quantify it.

It is about personal and historic observations documenting a shifting landscape over time, and how all of these things combine to create a new environment that is in constant flux.
