This summer, scientists from the U.S. Geological Survey set up at the closed lock 2 in Kaukauna and conducted a series of studies designed to assess the effects of a carbon dioxide barrier. The team built a large carbon dioxide infusion system and operated it in the closed lock and pond, taking thousands of measurements and recording data. This winter, scientists will assess the data to determine the effectiveness of a CO2 barrier in deterring fish, and the potential effects on animals, the river, and the atmosphere. Listen to this short video for more information and watch for the results in 2020!
