Portable Measurement System for in situ Estimation of Oxygen and Carbon Fluxes of Submerged Plants

The metabolism of submerged plants is commonly characterized by oxygen development. The turnover rates of carbon dioxide and other inorganic carbon species, however, are assessed only at distinct points in time after incubation or calculated through shifts in pH and total alkalinity. A novel three p...
