Researchers from Umeå University, amongst them Arcum-affiliated Marcus Klaus, have developed a new method that uses sound recordings to estimate how fast gases exchange between air and water.
Streams need to breath, just as humans, to stay healthy. This allows oxygen to improve water quality and sustain fish life, and greenhouse gases out which affects global warming. Gas exchange is driven by turbulence and bubbles, which in turn generate the characteristic stream flow sound.
