Project Summary: Coastal acidification is an emerging issue. Understanding this issue and the potential threats involves measurements and models that constrain the carbonate system. The Long Island Sound Study (LISS) has a new working group and efforts to begin to frame an approach to understand and manage coastal acidification. Here we propose to work on a simple instrument to accurately measure alkalinity in real time at high temporal frequency on the Connecticut River. The instrument uses a gravimetric approach to perform a Gran Titration. The work performed with this funding would help with assessing and improving its robustness in the field setting. If successful, this instrument could be deployed more broadly to help understand variability and model the carbonate system along the Long Island Sound (LIS).
