Strasser, M; Ikehara, K; Everest, JD et al. (2025): Line scan images of IODP Hole 386-M0090D
| Abstract: |
Collection of line scan 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. After longitudinal splitting high-resolution (100 pixels/cm) images of each core sections archive half was captured using the Tri-Sensor Core Logger (TSCL; NS Design). The camera provides a 16-bit red-green-blue color (48-bit) TIFF file, which were converted to JPG files for publication purposes. The RGB data derived from each image for each section are published under titles "Color data (RGB) of IODP Hole 386-M0090D". […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Visual core description of IODP Hole 386-M0085D
| Abstract: |
Collection of visual core description (VCD) sheets (hand drawn originals and digital representations) and lithologic composite plots from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). VCD was performed on unsampled archive halves of split cores, directly after linescan imaging, during the onshore phase of expedition 386, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. The lithology of each core section is represented on the hand drawn VCDs by graphic patterns next to the X-ray CT image of the archive-half core section. Further, a wide variety of features that characterize the sediment are indicated in additional columns. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): X-ray diffraction results from IODP Hole 386-M0091D
| Abstract: |
Results of X-ray diffraction (XRD) analyses 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): Moisture and density (MAD) from IODP Hole 386-M0083F
| 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. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): X-ray CT images of IODP Hole 386-M0087C
| 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): P-wave velocity of discrete samples (DPW) from IODP Hole 386-M0092D
| Abstract: |
P-wave velocity 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 P-wave velocity measurements were taken from the work halves approx. every 2 meter down core using syringes with an inner diameter of 2 cm. Samples measured 2.5–3 cm long for a sample volume of ~10 cubic centimetres. Samples were then shipped to the European Petrophysics Consortium (EPC) laboratory at the University of Leicester (UK) for processing. Measurements were performed with a Geotek P-wave logger for discrete samples (PWL-D). Measurements were attempted for each sample, however, the unconsolidated lithology of some samples proved unsuitable for the instrument (e.g. too soupy or too friable to be placed between the transducers).

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Description of lithologic section units of IODP Hole 386-M0091B
| 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-M0091B". […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (shear vane) from IODP Hole 386-M0086B
| 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. […] |
