Tide gauge location
The equipment is housed in a heated GRP building. The tide gauge consists of a pneumatic bubbler system supplying two full-tide and
mid-tide pressure points which are mounted on steelwork attached to one of the pier legs beneath the pier pavilion. All pressure
lines are monitored by the POL datalogger.
The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey auxiliary marks.
