title in nl

CALCIFICAT: Productie en desintegratie van calciumcarbonaat in kustsedimenten

Description in English

The production of calcium carbonate by benthic organisms is investigated and quantified in the Western Scheldt. Carbonate production will be estimated by combining macrobenthos biomass (available from extensive monitoring studies) with estimates of biomass turnover and CaCO3 production. The fate of this carbonate production will be assessed studying natural processes such as build-up of shell banks, and removal by human exploitation (using cockle and mussel fisheries as examples) and by dissolution. Carbonate dissolution, which is poorly known, will be studied in detail. Carbonate diagenesis will be studied through the state of the art modeling of in situ profiles, obtained by micro-profiling, conventional pore-water and solid phase sampling techniques. The thus obtained regional estimates of carbonate production and removal will then be compared with available estimates for the total carbon cycle in these regions to estimate the contribution of inorganic carbon to the coastal carbon cycle.

Abstract in English

Data were gathered in the framework of the "Production and dissolution of calcium carbonate in coastal sediments" (CALCIFICAT) project. Estimates for carbonate production and removal have been made for several locations in the Western Scheldt.
