We explore spatial and temporal variability of benthic metabolism in tidal sediments.

CO2 fluxes were measured from static chambers, at low tide, under light and darkness.
- ass="label">•
Fluxes varied over emersion, maybe due to changes in pore water amount and chemistry.

Higher net production was measured in bare mud than in seagrass meadow.

Persistent autotrophy was observed in upper sands, mid-bare muds and Zostera meadow.
