Photomicrographs

Microscopic images of discrete samples were acquired using stereo and upright light microscopes and captured on digital cameras. Image files were uploaded along with a brief description and a record of the microscopic and lighting conditions when the image was taken.

Data File format

	Exp: expedition number
	Site: site number
	Hole: hole number
	Core: core number
	Type: type indicates the coring tool used to recover the core (typical types are F, H, R, X).
	Sect: section number
	A/W: archive (A) or working (W) section half.
	Top offset (cm): position of the upper edge of the sample imaged, measured relative to the top of the section.
	Bottom offset (cm): position of the lower edge of the sample imaged, measured relative to the top of the section.
	Top depth CSF-A (m): location of the upper edge of the sample imaged expressed relative to the top of the hole.
	Bottom depth CSF-A (m): location of the lower edge of the sample imaged expressed relative to the top of the hole.
	Top depth CSF-B (m): location of the upper edge of the sample imaged expressed relative to the top of the hole.
	Bottom depth CSF-B (m): location of the lower edge of the sample imaged expressed relative to the top of the hole.
	Image filename: name of the JPEG image file.
	Contrast method: contrast method (e.g., brightfield, fluorescence, polarization).
	Illumination type: type of light source used for the image capture (e.g., transmitted, reflected, fluorescence).
	Objective: objective used during image capture, including the magnification value.
	Label Identifier: automatically generated name for a sample that is printed on labels.
	Timestamp (UTC): point in time at which an observation or set of observations were made.
	Text ID: automatically generated unique database identifier for a sample, visible on printed labels.
	Comments: observer's notes about the sample.
