Wave beaters

An interdisciplinary team validates a new generation of mesocosms to manipulate the water turbulence

To better understand the interaction between wind waves and the biological properties of freshwater ecosystems, it is highly desirable to reproduce coherent water motions generated by wind. In a new paper published in Limnology and Oceanography Methods, Hulot and collaborators from the CEREEP-Ecotron presents new mesocosms with wavemakers, also known as wave flumes, which are designed to emulate the effects of surface waves on the biological processes in shallow lakes. Preliminary experimental results show effects of mixing regime on water chemistry and plankton abundance. Challenging research questions on the ecological role of surface waves in shallow lakes can now be addressed with these mesocosms with wavemakers.
