Introduction
The SHIL ( Section Half Image Logger (SHIL) creates high-resolution images, both line scans of sections (predominantly from the archive half) and 360° images of hard rock pieces.
...
- Double-click the MUT icon on the desktop (Figure 1a) and login using ship credentials. For more information on data uploading see the "Uploading Data to LIMS" section below.
- Double clikc the IMS icon (Figure 1b). IMS initialize's initializes the instrument and checks the movement of the track. Once initialized, the logger is ready to measure a section. For hard-rock 360° images, please see section below.

...
Note: If you see any change in image quality, please contact the PP or Imagining Imaging technician.
- For sediment cores: Using either a stainless steel spatula or glass slide, scrape the surface of the core. Scrape sections from bottom to top, ensuring that the section surface is clean and flush to the section liner. If necessary, remove excess moisture using paper towels.
- Place section in the core tray. Make sure the section is oriented blue endcap towards camera, and is flush against the red benchmark (Figure 2).
Figure 2. - Correct core position.
Note: If a Whole-round sample (predominantly IW's) has been taken from the end of section (indicated by a yellow endcap), a foam spacer needs to be placed at the bottom of the section half. Whole-round samples are predominantly 5 or 10cm in length; the foam spacer MUST match the given length of the sample taken.
...
- Click START. The Section Information screen is displayed (Figure 3).

2. Place the cursor in the SCAN field and scan the section label. SAMPLE ID and LIMS ID automatically fills. These This ID tags contain tag contains information on expedition, site, hole, core, section number and length.
...
Note: Selecting 360 Imaging, intializes intializes Imaging Control, allowing a user to select the angle of rotation. For more information see section of guide below.
Wet/Dry:
Soft Sediment: Used for sediment cores
...
Sampled-Altered: Used for cores which have either been sampled , or altered in anywayany way.
Note: Natural geological alteration within the core material , does not qualify as a Sampled-Altered condition.
Note: To scan a Working section half, open the MANUAL tab. Click the Section Half drop box and Select W (Figure 4). To return to scanning Archive halfs, the Section Half value will have to be reset. Open the MANUAL tab, click the Section Half drop box and re-select A.

5. The imaging assembly moves to the bottom of section. A line scan image, will be acquired (Figure 5).

Note: If the Dropped Lines (located in the far left corner) indicator is orange, contact the PP or Imaging technician.
6. After the scan is complete, the Image Crop window is displayed (Figure 6).

7. Check the position of the Green crop lines, using the Show Top of Image and Show Bottom of Image buttons. The cropped image should include the full section length and the additional foam spacer (if applicable). The ruler or red benchmark should NOT be included within the image.

11. MUT is used to upload data to the LIMS database. See section "Uploading Data to LIMS" for more information.
12. Once uploaded, data is available to view on LORE and LIVE. If data is not instantly visible, please contact the PP or Imaging technician.
...
3. Remove the 0° aluminum strip, in addition to two side pieces, from the scanning tray. Place the oriented pieces into the scanning tray keeping their offsets as close as possible and align the splitting line with the 0° orientation (Figure 7).

...
- Click the MUT Icon. Log in using database credentials.
- Once activated, the list of files from the C:\DATA\IN directory is displayed. Files are marked ready for upload by a green check mark (Figure 8).
