Tide gauge location
The GRP building houses the tide gauge system which consists of a POL data logger monitoring the anemometer, wind vane, and the three pneumatic bubbler systems. The pressure points being mounted on steelwork which is attached to the sheet pile wall.
The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey auxiliary marks.
