Summary
The duties of the Imaging Specialist were shared by different individuals for the expedition since we sailed with reduced staff. Aaron De Loach and Nicolette Lawler covered the physical properties and close-up area, Sandra the remaining tasks.
Equipment
SHIL:
Performed well for sediments with the newly installed lights, even though we still have the ongoing issues of green lines in the images. Some images were sent back to shore to the Imaging Specialist to perform a quality check.
We had an issue with the wet hard-rock images as the bright light was harshly reflected from the dark surface - for more information see details in 384 physical properties tech report.
Step counters for the microscope stages:
The point counters were found, investigated, and tested. The setup has two parts: the moving stage that attaches to a microscope stage, and a digital counter that connects to the stage. When a user logs counts on the digital counter the stage will move to left a pre-defined amount. We have four digital counters and three stages. They are located in the microscope lab in cabinet 3D-4. A user guide was written and can be found in the Microscopy Laboratory Manuals area.
Microscopes:
One of the Axioplan microscopes was configured for smear slide usage, including a 63x oil objective that was cleaned after usage.
PICAT:
was used. We had an issue with the light source. The transformer had several electronics issues, that were fixed by the ET. The light bulb in the color head was malfunctioning as well. The bulb was removed, tested, and plugged back in. All of the components are back in working conditions. The light bulbs used are the regular 12V halogen.
the camera lens cover is missing. A new one is on order.
Closeup Station:
The closeup station was setup after the camera was removed in preparation for plan zulu. Closeup images of a whole round were taken to capture an unexpected curve in the rock cored with one of the new drill bits.
SEM:
was not used for scientific samples.
Software
Samsung Gear 360:
The software could not be found.
The camera is available onboard and seems to be working.
ImageCapture:
Was used for microphotographs, closeups, and thin section images.
Images
SHIL images were sent to shore for cross-checking by image specialist.
The Virtual Photo Table app was running during coring.
Quadrant images were produced, but not all were stitched together to produce the 360 composites.
General images of the laboratory configuration were requested by the Laboratory Officer in order to update the IODP websites.
Image Files Produced
4 Close-ups Images (CLOSEUP)
9 Photomicrographs (MICROIMG)
36 Thin-section Images (TSIMAGE)
58 Core composite images (COREPHOTO)
343 Line Scan Images (LSIMG)
385 Quadrant Images (WRLS)
30 Whole-round 360 (WRLSC) - not all of them were processed due to time restraints
PR images
Weekly photos were taken, approved, and captioned on the ship. Metadata tagging was done on shore from week 3 on.
Documentation
The Imaging/Microscope Laboratory confluence site was updated, documentation was added for:
General Folder structure for an expedition,
Guidelines for required metadata/keywords and development of a metadata template for an expedition,
PICAT energy source information,
T-shirt printing instructions, ballots,
ID card templates,
Mug Photo/Group photo templates/Caption document,
Close-up template,
How to get RAW pictures converted - RAW - DNG - JPEG,
How to add an expedition metadata template and keywords to images with Adobe Bridge, and
a new guide for 360-quadrant image-stitching and a short quick start guide for ImageGrabber was developed, and
the 360 composite software guide was transferred from word to confluence.
Shipments
Drobo drive is being sent to shore to sort through files that might be missing there and to transfer 384 data to the shore database. It is expected to be back for the departure of Expedition 390 (October 5, 2020).
