👉 Unsoiling is a process used in marine engineering and navigation where the seabed is modified so that it becomes less likely to erode, or become unstable due to sea salt and other marine salts. This can help prevent coastal erosion and protect marine habitats from further degradation. The term "unsoiling" refers to the action of removing the salt content from the seabed, which in turn reduces the risk of erosion. This process is often carried out by applying a layer of sand or gravel on
