Avonmouth tide gauge site

The tide gauge building is located on land between the wartime jetty and the fuel storage depot, with the measuring points being attached to the superstructure of the wartime Jetty. Click here to see a map of the site in a separate window.

The tide gauge equipment is housed in a GRP building with the power and signal wires running under the land, along the jetty and down to the transducers. Both signal lines are monitored by the POL data logger.

The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey auxiliary marks.
