Antarctic Sediment Core X-Ray Images from Cruise NBP01-01

X-radiograph images of u-channel subsamples from jumbo piston cores collected during Cruise NBP01-01. The images capture sediment lithology with exposure times varying between 30-45 seconds. The cores were processed and subsampled at the Antarctic Research Facility, Florida State University, under the organization SCIOPS.

Use Cases

• Classify sediment lithology types by analyzing texture and density patterns in the x-ray images.
• Measure laminations and stratigraphic features within the 2 cm x 2 cm u-channel samples to reconstruct depositional timelines.
• Correlate visual sediment properties from the radiographs with other core measurements like physical properties or geochemistry.

Strengths

• Images capture detailed internal sediment structure from physically continuous u-channel subsamples.
• Exposure times (30-45 seconds) were adjusted for lithology to optimize image contrast.

Limitations

• The exact number of images, core coverage depth, and spatial resolution are unknown.
• Sample representativeness is limited to specific jumbo piston cores from a single cruise (NBP01-01).
