Wick tide gauge site

The tide gauge building is mounted over an unused stilling well at the end of Wick Harbour next to the ship repair slipway. The pressure points are located directly beneath the building.

Tide gauge location

The tide gauge equipment is housed in a GRP building and consists of a pneumatic bubbler system with two full-tide and a mid-tide pressure points mounted on steelwork attached to the stilling well. All three pressure lines are monitored by the POL data logger. A pressure signal is also supplied to an Ott pneumatic gauge for the Harbour.

Tide gauge location The tide gauge is levelled to the tide gauge bench mark support by Ordnance Survey auxiliary marks.
