Details

This new book discusses and presents research when examines dissolved inorganic carbon in aquatic sediments. The sources of dissolved inorganic carbon (DIC) in pore waters of three aquatic sediments were determined and compared: sediments from boreal Lake 658 in northwest Ontario, sub alpine lacustrine carbonate rich sediments of Lake Bled, Slovenia, and coastal marine carbonate rich sediments in the Gulf of Trieste, N Adriatic Sea. For this purpose the isotopic composition of DIC (δ13CDIC) in pore water was coupled with a comprehensive pore water chemistry and sediment environment. The model accounting for diffusion, irrigation, and the remineralization of organic carbon was used to better understand the observed variations in concentration of DIC. (Imprint: Nova)
