Table 2.

Spearman's rank correlation analyses between biogeochemical fluxes (O₂, ${\text{NO}}_3^{-}$ + ${\text{NO}}_2^{-}$, ${\text{PO}}_4^{3-}$, ${\text{NH}}_4^{+}$), sediment biomarkers (C:N, C-chla:TOC, chla:phaeo ratios, and biomass of TOC, chla and phaeopigments), and bioturbation variables (Db and r). Significant values are marked in bold (p < 0.05).
