The Aquatic Bio-optics and Biogeochemistry Laboratory enables researchers to study the effects of climate change and permafrost thawing on lake water transparency and mixing dynamics and their multiple impacts on the microbial food chain, greenhouse gas emissions, and oxythermal habitat. Research at the Aquatic Bio-Optics and Biogeochemistry Laboratory also focuses on developing optical equipment for early detection of algal and cyanobacterial blooms and other problems related to water browning.

This station is a common research area for all ÉTS professors and their public or private partners with a total surface area of approximately 703 m2. STEPPE-ÉTS is dedicated to the development and pilot-scale validation of technologies (knowledge and practices) to protect the environment at the preventive, remedial and curative level in a systemic perspective and responsible evolution of human activities. To develop technologies, knowledge and acquire information to protect the environment, the STEPPE-ÉTS infrastructure includes a pilot hall for large-scale studies, two metrological laboratories, a biological laboratory, a computer lab and two rooms with controlled environment.
In addition to these spaces, STEPPE-ÉTS's functionalities make it possible to access a fleet of analytical equipment and pilot treatment or remediation processes (water, atmospheric emissions, soils, residual materials). If a partner so desires, STEPPE-ÉTS can also put him in touch with other services or appropriate human resources to improve his project.
