The Penn State Environment and Natural Resources Institute will host another in its series of Water Insights Seminars on April 2 on the Carbon Biogeochemistry of the Chesapeake Bay.

Dr. Raymond Najjar, Professor of Oceanography, Department of Meteorology and Atmospheric Science at Penn State, will make the presentation.

Carbon is a currency for tracking many important processes in the coastal environment, including hypoxia, eutrophication, metabolism, burial, and fisheries yields.

Long-term measurements of pH and alkalinity in many water quality monitoring programs provide an opportunity to learn how carbon cycling has changed in estuaries over decadal time scales.

In this presentation, Dr. Najjar will present an analysis of more than 30 years of pH and alkalinity measurements in Chesapeake Bay, with a focus on quantifying spatial, seasonal, and interannual variability in the air–water carbon dioxide flux in the mainstem bay and calcium carbonate sources and sinks in the tributaries.

The Seminar will held from Noon to 1:00 in Room 312 of the Ag and Bio Engineering Building on Penn State’s main campus in State College and is available online via Zoom.
