## Field Data Sheet 

**Field Data Sheet**
-   Rod SET data is collected in 4 directions with 9 pin measurements recorded for each direction.
-   The four directions (bearings in degrees) should be the same each time the instrument is read.
-   If for some reason one of those directions changes (i.e. the plot is disturbed in some way and must be abandoned), the new direction should be recorded in the Site History.
-   The numbered pins should always be read in the corresponding hole.
-   The same RSET instrument should always be used at a site.

## Field Data Sheet Cont’d

**Field Data Sheet Cont’d**
-  Detailed comments should be recorded about the surface that the RSET instrument is being leveled to.
-   If the pin lands in a hole, on a large root or clump of grass or if the surface is a slurry should be noted in the comments section.
-   Water level should be noted in the site conditions section.

## Data Entry

**Data Entry**
-   Data from field sheet is entered into SONRIS.

## Data Retrieval

-   Data goes into a buffer before it is accepted into the database.
-   Data can be retrieved from the buffer via download for QA/QC.

## Data Retrieval

-   Data is output from SONRIS is the format below.

## QA/QC Process

-   The data from the buffer should be checked against the field sheet for correctness.
-   The verified data should be QA/QC’d further to check for some basic consistencies:
- That there are 36 measurements for a site, 9 in each direction.
- That the directions were the same as last time.
- That the same instrument was used as last time.
- The verified data should further be checked for quality by calculating the difference in pin height (elevation change) over the time interval.
- Data should be plotted with elevation change means (n=9) ± standard error for each direction.
- Outliers, defined here as observations outside the 95% Confidence Interval for the mean in a direction should be noted.  Flagged observations should be addressed in the data report.

## Data Review Example

**Data Review Example**
**  ****Using Exported data from SONRIS, compare the most recent and previous RSET sampling.  **
**  ****Report elevation change (mm) and 95% Confidence Intervals for each direction.  **
**  ****Identify outliers and review comments. **

## Data Review Example	

-   Summarize data by directions and for consistency.
-   Plot mean Elevation Change ± Standard Error by direction.
-   If means and variations are not similar, attempt to determine why and re-examine data and comments.

## Troubleshooting

- Data goes back up the QA/QC chain and is corrected if:
-   Data weren’t entered correctly into SONRIS
-   Problem observations were not identified
-   Sampling was inconsistent (i.e. instrument and directions)
- The Site History Report should be updated if:
-   Disturbance to the SET has occurred.
-   A direction needs to be replaced.
