| Originator: | Same |
| Original Data: | Analog |
| Instrument Type: | Stevens Model A float and well gauge with a Telog Instruments Model R-2108 potentiometric recorder connected to the sprocket wheel. |
| Digitized Interval: | 1 second |
| Present Data: | Hourly, daily, and monthly values obtained by: |
| Hourly: | Average of 3600 1-sec samples per hour. |
| Daily: | 119-point convolution filter (Bloomfield, 1976) centred on noon applied to the hourly data with respective periods of the 95, 50, and 5% amplitude points at 124.0, 60.2, and 40.2 hours. |
| Monthly: | Simple average of all daily values; calculated if 7 or fewer days are missing. |
| Span of Data: | 23 March 1992 - 23 April 1993 |
| Gaps > 1 Month: | None |
| Time Reference: | GMT (hours 00-23) |
| Space-filler Flag: | -9999 |
| Units: | Millimeters |
| Missing Data Flag: | 99999 |
| Reference Level: | The sea level heights are relative to a local (arbitrary) datum. |
| Comment: | The gauge is located on Lee Stocking Island. The daily and monthly means do not reveal any obvious reference level shifts. The timing of the hourly values is good. |
