Summer Degassing Rates of Carbon Dioxide from First Order Streams in the Towson Area, Maryland

Abstract

Four first order streams exhibiting different levels of urbanization and lithology were sampled in a two-mile radius of Goucher College to determine their carbon dioxide fluxes to the atmosphere.  Temperature, pH, and alkalinity values, in particular, were measured and used to calculate carbon dioxide fluxes of each stream.  Average fluxes range from 557.1 to 31,018.3 gC/day in 2013.  The results indicate that lithology appear to have a stronger effect on overall carbon emissions of each of the streams in relation to their level of urbanization.
