(a) NEE, Net ecosystem exchange; g C, grams of carbon.
(b) Continuous measurements: eddy covariance (EC) or static chamber (SC). Positive values = atmospheric carbon dioxide (CO2) source. Negative values = atmospheric CO2 sink. Annual estimate (mean) provided.
(c) Mudflat habitat (very little data available in literature)."^^ . . . . . .
