In the Anthropocene era, human intervention has significantly transformed our environment, blurring the lines between the natural and artificial. This project places an emphasis on this viewpoint in environmental philosophy, and its role in the practise of the industrial designer. Drawing on research of two science advisors and their findings, the focus of Submerged Wetlands is to create a small-scale design of an artificial wetland, that works to mitigate cyanobacterial bloom, a growing phenomena caused by climate change, specifically agricultural nutrient runoff and global warming.The material choices,, the plant Juncus Repens as an acting low-tech filter to remove excess nutrients, the choise of reed grass and the consideration of what people and space the design interact with, comes out of natural fieldwork, interviews, lab tests and excursions to institutions. In submerged wetlands, the properties of marinal vegetation are being speculatively utilized in a design proposal to construct submerged gardens under buoys in recreational areas around the lake Mälaren in Stockholm. These areas are subject to cyanobacterial blooms, commonly referred to as algae bloom, which pose a threat to humans and aquatic species. Together eith a body of scientific research on wetlands, soil and ccyanobacterial blooms, the designed solution submerged wetlands takes into account the spectator's need for a third place, their emotional disposition towards the climate crisis and presents a demonstrative and accessible formation in the form of an artificial wetland.
