Copepod carcasses were produced by exposing female specimens of cultured Acartia tonsa to anoxic conditions for 2 hours. Carcasses were incubated in gas-tight glass vials equipped with an internal optode for contactless oxygen measurements at 5 different temperatures ranging between 4 and 20°C. Carcass-associated oxygen consumption was measured for varying time periods. The obtained respiration rates were converted to carbon mineralization rates using 3 different theoretical values for the respiratory quotient and 3 different theoretical values for bacterial production and then to the cumulative carbon loss relative to the initial carbon contents of the carcasses.
