Tide gauge location

The tide gauge equipment is housed in a GRP building. The pneumatic bubbler system consists of two full tide and mid-tide pressure points mounted on steelwork attached to one of the pier supports. All three pressure lines are monitored by the POL data logger.

Tide gauge location The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey of Northern Ireland auxiliary marks.
