Utilizing infrared-color imagery to contrast water and vegetation, this Landsat time series tracks 40 years of dynamic shifts across Louisiana’s fragile coast. From abrupt hurricane-induced flooding to the gradual, permanent drowning of vital marshes, these visualizations capture an ecosystem in perpetual motion.",
