Figure 2: Biogeochemical rates from sampling stations.

Rates (mean±s.e.m.) of (a) Denitrification of ¹⁴NO₃⁻ (D₁₄), (b) amount of D₁₄ fuelled by nitrification-derived NO₃⁻ (D_n), (c) anammox (A₁₄), (d) proportion of N₂ produced by A₁₄, (e) dissimilatory ¹⁴NO₃⁻ reduction to NH₄⁺ (DNRA₁₄) and (f) sediment oxygen demand (SOD). Note different y axis scales.
