Sebkha Ariana, Protected wetland near Tunis, Tunisia
Sebkha Ariana is a saline wetland on the northwestern coast of the Gulf of Tunis, spread across a large area with distinct soil layers and varying terrain. The landscape consists of flat, salt-encrusted plains that fill with water seasonally and then dry out again.
The area formed thousands of years ago through geological processes as marine landscapes transformed into coastal wetlands. This long transformation shaped the current structure and composition of the terrain.
Scientists conduct regular studies of the wetland's foraminifera deposits and sediment cores to understand environmental changes in North African coastal regions.
The area is accessible, but visitors should know that the terrain can be muddy and salt-covered, requiring sturdy footwear. The best time to explore is typically after the dry season when the paths are more stable.
The soil layers here contain remnants of marine organisms and continental materials that document different environmental phases. Researchers use these natural archives to understand the climate history of the region.
