Project description: We are looking for two PhD students who will work with the effects of climate change on ice-covered lakes in the Northern Hemisphere. The main objective of the global research project is to assess how lake ice properties such as crystal structure, thickness and transparency will change in a warmer climate and how these changes will affect ice stability/safety as well as ecological and biochemical processes in different types of lakes. The project includes field, experimental and modeling work where one PhD student will focus on the physical and modelling aspects of the project and the other one on the ecological and biochemical aspects. Since the projects are of very high societal value they also include some outreach activities. The PhD students will work in a team together with researchers from Gothenburg University and experts in the national network SITES ( and the international network GLEON (Global Lake Ecological Observatory Network,
