Strasser, M; Ikehara, K; Everest, JD et al. (2025): Smear slide descriptions of IODP Hole 386-M0091A
| Abstract: |
Descriptions of smear slides 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): X-Ray fluorescence (XRF) of discrete samples from IODP Hole 386-M0083B
| Abstract: |
Results of X-Ray fluorescence (XRF) on discrete samples 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, followed by an onshore phase onboard D/V Chikyu between 2022-02-14 – 2022-03-15. During the onshore phase a set of solid-phase samples, with a volume of approx. 10 cubic centimeters each, were taken with the purpose to be later on split into aliquots for the following three analyses: X-ray diffraction, carbon and X-ray fluorescence. The bulk solid-phase samples were taken from the work halves of core sections at about one sample per meter on average. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (shear vane) from IODP Hole 386-M0084B
| 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. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Color Reflectance (Spectrophotometer) of IODP Hole 386-M0088D
| 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): Core close-up images of IODP Hole 386-M0094B
| Abstract: |
Collection of split cores' close-up 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. Images were obtained during the onshore phase of the expedition, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. Close-up photos were taken utilizing a standard photo camera by sedimentologists during visual core description. Decision on imaged intervals was subject to the core describers in charge. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Core-section summary for IODP Site 386-M0093
| Abstract: |
List of recovered core sections from the above given site 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. Cores have been acquired by the use of a Giant Piston Coring (GPC) System. Recovered cores were divided into approx. 1 m long sections that are numbered sequentially from the top, starting at 1. Following IODP convention, material recovered from the core catcher of a sedimentary core is treated as a separate section labelled CC for core catcher and placed below the last section recovered from the core barrel. Most core catcher sections were placed in a bag due to their consistency. The IODP standard naming of sections includes the following information: expedition number, hole, core, core type and section. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (handheld penetrometer) from IODP Hole 386-M0085A
| Abstract: |
Shear strength from handheld penetrometer 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 handheld (pocket) penetrometer equipped with a 10 mm diameter tip. The tip was pushed 6.3 mm perpendicular to the split core surface with the measuring pin downward until the groove marked on the tip was even with the level of the core surface. The resulting resistance (compressive strength) was read from the device and used to calculate undrained shear strength. At each measurement depth, three measurements were conducted and the resulting undrained shear strength averaged. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): X-ray CT images of IODP Hole 386-M0083A
| 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): Moisture and density (MAD) from IODP Hole 386-M0095A
| Abstract: |
Moisture and density (MAD) data from discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). During the onshore phase of expedition 386, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu, discrete samples for MAD measurements (bulk density, dry density, grain density, water content, porosity, and void ratio) were taken from the work halves using 10 cubic centimetre syringes at an approx. down-core resolution of every 2 meters. Sampling depths were adapted and slightly modified for layers of special interest, such as tephras. Samples were processed and measured directly after sampling onboard Chikyu. For the measurements themselves samples were transferred to glass beakers of known weight and volume. […] |
