All data have been compared with the current Harmonic Constants library, and residuals checked. Records have been visually inspected for spikes, datum shifts and timing errors.
The tide gauge at this site is situated within an estuary and at times can be affected by freshwater influences particularly during stormy periods or after snow melt events. When affected the data is flagged as suspect and should only be used with caution. No corrections are applied to the data.
Where there are problems with the primary channel, data may be available from the backup channel. Please contact enquiries@bodc.ac.uk for more information.
In August 1986 the Dataring system was installed. The bubbler gauge (ASLVBG02) replaced the Munro gauge (ASLVZZ01). There is a gap in the file where the gauge was changed.
1993 - The processing of the 1993 file has left a null value at the start of the file (00:00 hours 01/01/1993). This is due to the sampling interval changing from 60 to 15 minutes and the first data point being too far from 00:00 to interpolate.
February 2003 - File output has been altered so that all values fall on the quarter hour and gaps are filled in with null values, marked with an 'N' flag.
March 2003 - Residuals (observed minus predicted sea level values, measured in metres) now included in the file output.
On 03/02/2012 a new data logger was installed. Tests were carried out to ensure the logger was functioning correctly, resulting in some data being lost.
November 2012 - The file output has been altered to reflect the Contributor name change from Proudman Oceanographic Laboratory to National Oceanography Centre, Liverpool. Also, the Parameter code has been improved and now uses a controlled vocabulary.
Please note: After a visit to the site in June 2004, when the mid tide channel was enabled, it was found that there had been an error in the levelling. From 14/11/2000 12:00 GMT to 23/06/2004 00:45 GMT all channels have been raised by 38mm. The affected files have been corrected to chart datum.
Missing and suspect data have been reported on the following day numbers:-
