When analyzing the ratio of reactive C pool to total carbon, it was
found that mudflats the highest ratio of reactive C was found in superficial
bioturbated sediment (23.5%), followed by superficial non bioturbated
sediment (22.0%), while mounds (10.2%) and deep non bioturbated
sediments (8.7%) had the smallest proportions (Table 3).
These patterns are similar in salt marshes,where burrow walls, superficial
bioturbated, and superficial non-bioturbated sediments had the
highest proportions of reactive carbon (16.6, 28.1 and 26.3% respectively;
Table 3). Lowest contributions were obtained in both deep bioturbated
and non-bioturbated sediments (5.2 and 6.0% respectively).
