Example of acceleration patterns according to tidal and circadian phases within the tidal zone. The graph shows the data of one female crab (tag ID 3723, Table S1) at one acoustic receiver within the Nete River (tidal zone) from 25 to 27 December of 2021 (time in UTC). Acceleration (m s−2) measurements are shown as black dots and the blue line indicates the water level (mTAW) over time. The dark grey boxes indicate night, light grey boxes indicate twilight (i.e. dusk and dawn) and white boxes indicate day
