System Status

SHIL

The SHIL worked well, no issues experienced during the expedition, and calibration had been done multiple times during port call and transit.

Section Half Image

• All images (.TIFF and .JPEG) were methodically checked and retaken when necessary.

• After a week of operation, two scientists mentioned that the color of SHIL image didn't look bright enough and was different from looking at cores by eyes, and asked if we could edit the image. Most cores we got in this expedition are dark colored sediment, which made the images turned out darker and the contrast weren't strong enough to see the details on VCDs.  We checked through the calibration settings and it look fine, so we decided not to change any configuration on SHIL and keep the same setting through the whole expedition. 

• We tried to pull out some images and edit on Lightroom by using the color checker (figure1), and tried to apply on dark-colored sediment core images (figure2), but the scientists decided to set the edit parameters by eyes and feeling. Finally we suggest that if the images were too dark for reports, they can download and edit them individually by themselves and add the note for the editing. We edited and exported all the images using their settings for all sections of one hole for them, and afterwards they haven't mentioned about it again.  

• The default setting of SHIL was "section" instead of "section half" in the beginning of the operation, when the barcode couldn't be scanned, scientists selected the core sections manually, but sometimes selected to section by mistake, and when SHIL images were parented to section, they could not show up in core composite images. We asked everyone to keep an eye on the setting, and also the application developers helped to change the default to "section half", and no issues after.
