During Friday (31 March) and Saturday (01 April) there was relatively intense rainfall (~5mm/hr).  This has had the effect of increasing the river Tamar flow rate, and elevating the level of turbidity, nitrate and reducing the salinity.  The tidal cycle can clearly be seen interacting with this with a periodicity of ~12 hours.
