This video marks the work of one researcher working to getting baseline data for acidification monitoring in Lake Huron, a project supported in partnership with the NOAA Ocean Acidification Program, Thunder Bay National Marine Sanctuary and the NOAA Great Lakes Environmental Research Laboratory. From the samples taken, scientists are able to measure and track water chemistry and enables understanding and assessment of the carbonate system. These include pH levels, total alkalinity, dissolved inorganic carbon, and partial pressure of carbon dioxide. Changes in these factors could impact aquatic life, water quality, recreation, and industry. Having solid, foundational data will be a helpful tool for the years to come.
