Tide gauge location
The equipment which is housed in the switch room of the Port Control building consists of an Ott pneumatic gauge and a pneumatic bubbler system. The bubbler system supplies two full-tide pressure points which are mounted on steelwork attached to the pier wall.
All three pressure lines, wind speed and direction are monitored by the POL data logger.
