Comment:
Calculated approximated total benthic foraminiferal denitrification rates and nitrate storage at the different sampling sites.// The column "Foraminiferal denitrification without Assumpt. B" covers the foraminiferal denitrification for species where// literature data for the individual rates was available plus the denitrification rates derived by assumption A. //Also listed are foraminiferal abundances and pore water nitrate concentrations in the top cm of the sediments. //The elevated pore water nitrate concentrations at samples from the pore water press most propably result //from squashed foraminiferal as well as Thioploca and Beggiotoa cells. //Errors of foraminiferal nitrate storage are based on the SEMs from Piña-Ochoa et al. (2010a).
