Urbanization and industrialization, which come with population growth in the world and in Turkey, bring along various environmental problems. The liquid wastes of all cities, whether coastal or not, eventually reach the seas, and this pollution accumulates and becomes a big problem that cannot be cleaned naturally. These issues lead to the formation of mucilage, which is a natural phenomenon seen in oceans and seas, commonly referred to as sea snot or marine mucus. Mucilage, which threatens the ecosystem, causes serious damage to sea creatures and biodiversity. Through a bibliometric analysis, this study examines the formation process, causes, and environmental influences of mucilage events in the seas of the world and Turkey, and explores solutions for reducing mucilage. Findings present the significance of mucilage formation and discuss the necessary measures that should be taken to mitigate this issue.
