Strasser, M; Ikehara, K; Everest, JD et al. (2025): X-ray CT images of IODP Hole 386-M0086A
| Abstract: |
Collection of X-ray Computed Tomography (CT) images from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. This was followed by an onshore phase onboard D/V Chikyu between 2022-02-14 – 2022-03-15. X-ray CT scanning was performed on whole-round sections on board D/V Chikyu in July 2021, after the offshore phase and prior to the onshore phase, using a Discovery CT 750HD (GE Medical Systems) that produces 32 0.625 mm thick slice images every 0.4 s. Data generated for each core consist of core-axis-normal planes of X-ray attenuation values that are 512 × 512 pixels in size. Data were stored on the server as DICOM formatted files. The DICOM files were restructured to create 3-D images for further investigation. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (fall cone) from IODP Hole 386-M0092A
| Abstract: |
Undrained shear strength data from fall cone testing of the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). This dataset was obtained at the end of the core processing workflow during the third phase (Personal Sampling Party, PSP) of expedition 386, which took place between 2022-11-15 – 2022-11-30 onboard D/V Chikyu. Measurements were performed on the work halves of core sections at an interval of approx. 1 meter using an ELE International fall cone penetrometer (STANDARD BS1377) with the following cone specifications: 35 mm cone, 30 degrees angle, around 30 g, stainless steel, 3.25 (+/-0.05) mm rod diameter. The fall cone penetrometer measures the penetration of a cone as it free falls and embeds itself in the sediment. During testing, the cone (pointing downward) was lowered, so that it just touched the surface of the split core before it was locked in place with the dial gauge reading noted. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Color Reflectance (Spectrophotometer) of IODP Hole 386-M0092D
| Abstract: |
Color reflectance spectrophotometry and colorimetry data from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The data where obtained during the onshore phase of expedition 386 which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. After longitudinal splitting of the core sections, each archive half was scanned by the Tri-Sensor Core Logger (TSCL; NS Design) including a noncontact imaging spectrophotometer (MetaVue VS3200; X-Rite), recording data at 2-cm sampling interval. The obtained data is represented in the L*a*b* color coordinate system, where L* is a total reflectance index ranging 0%–100%, a* is green (<0) to red (>0) chromaticity, and b* is blue (<0) to yellow (>0) chromaticity. L*a*b* values were transferred into RGB values using the MATLAB routine lab2rgb. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Description of lithologic section units of IODP Hole 386-M0092D
| Abstract: |
Description of lithologic section units from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The content of this dataset is based on the visual core descriptions (VCD) done by sedimentologists during the onshore phase of expedition 386 (2022-02-14 – 2022-03-15 onboard D/V Chikyu). For digitalization of the information, content of the hand-drawn VCD sheets was transferred into the Drilling Information System database. The present dataset forms the basis for the digital lithologic columns and composite plots archived under the titles "Visual core description of IODP Hole 386-M0092D". […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Physical properties (MSCL) of IODP Hole 386-M0090D
| Abstract: |
Multi-Sensor Core Logger (MSCL) data (P-wave velocity, gamma ray attenuation (GRA) density, magnetic susceptibility, natural gamma radiation (NGR), noncontact resistivity (NCR)) from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). These data were obtained from whole round core sections by means of a Geotek MSCL during the offshore phase of the expedition. The offshore phase of expedition 386 took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. As the aforementioned parameters are sensitive to temperature core sections were stored for at least 6 hours after arrival on deck before measurement to allow for temperature equilibration. The core physical properties were measured at predetermined optimal instrument-based spatial and temporal sampling intervals. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Smear slide microscopy images of IODP Hole 386-M0084A
| Abstract: |
Collection of smear slide microscopy images from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. This was followed by an onshore phase onboard D/V Chikyu between 2022-02-14 – 2022-03-15. During the offshore phase, smear slides were prepared from paleontology samples collected with a tip-cut syringe from section ends every 5 m. During the onshore phase, smear slides samples were collected every 2 m to complement visual core description observations and identify the composition of fine-grained sediment. The smear slides were prepared by putting a small amount of sediment on a glass slide mixed with distilled water. The slide was subsequently evaporated on a hot plate, and the dried sample was mounted in Norland Optical Adhesive 61 using ultraviolet light. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (shear vane) from IODP Hole 386-M0093A
| Abstract: |
Shear strength from automated shear vane (AVS) of the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). This dataset was obtained at the end of the core processing workflow during the third phase (Personal Sampling Party, PSP) of expedition 386, which took place between 2022-11-15 – 2022-11-30 onboard D/V Chikyu. Measurements were performed on the work halves of core sections using a Wykeham-Farrance AVS. The apparatus consists of four vanes perpendicular to each other that are inserted in the sediment to their full length while attempting to minimize disturbance to the sediment. A motor loads a helical torsion spring and the bottom of the spring is united to the vane. Therefore, the bottom deflection of the spring records the angular displacement of the sediment, from which undrained shear strength has been calculated. […] |
