Gases and gas release from inland waters have recently received great interests in the limnological research as essential players in the carbon cycle: released gases such as carbon dioxide and methane are the most important contributors to the greenhouse effect. However, the relevance of gases goes far beyond this. Gases play a central role in limnology. Oxygen is a central agent for the metabolism of higher organisms, while carbon dioxide is a requirement for photosynthesis. Some lakes store immense amounts of gas which, when sudden released, threatens animals and humans on land. Degassing due to instantaneous pressure change and strong turbulence mixing upon discharge from reservoirs not only results in significant emissions of methane, but also causes oversaturated dissolved gases in water, threatening downstream fish species. Our further understanding of interactions between inland waters and the atmosphere under global change is limited. We invite presentations covering a wide range, such as the nature of gas production via microbial processes, transport of gases, solubility, ebullition, diffusive exchange at the air-water interface and gas tracing. We also welcome presentations of methodological development or the application of novel methods ranging from micro-scale experiments to upscaling exercises.
