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): X-ray CT images of IODP Hole 386-M0084D
| 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): Interstitial water geochemistry results of IODP Hole 386-M0091B
| Abstract: |
Results of interstitial water (IW) geochemistry 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. Sampling for IW geochemistry took place offshore immediately upon core recovery using Rhizon samplers. A total amount of approximately 15 mL IW per sample were extracted from the core sections over a maximum rhizon retention time of 6 hours. IW main samples were subsequently split into as many as seven fractions for the following IODP standard measurements: sulfide (1.5 mL IW + 0.6 mL ZnAc 2.5%), salinity (0.5–1.5 mL), pH and alkalinity (3–4 mL), ammonium (0.5–1.5 mL), cations (3 mL IW + 0.03 mL HNO3), and anions (3 mL).

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Natural remanent magnetization data from IODP Hole 386-M0087B
| Abstract: |
Natural remanent magnetization (NRM) data 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. Because the diameter of the split section (12.5 cm) is larger than the magnetometer entrance (8.1 cm), U-channel samples were taken from the center of each working half during the onshore phase. Measurements were conducted likewise during the onshore phase using the long-core superconducting rock magnetometer (2G Enterprises, model 760) installed on D/V Chikyu. Due to time constraints paleomagnetism measurements were limited to NRM with 5 mT demagnetization, with measurements typically made at 2 cm intervals. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Line scan images of IODP Hole 386-M0089C
| 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-M0089C". […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Visual core description of IODP Hole 386-M0092B
| 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): Foraminifera occurrences of IODP Hole 386-M0083F
| Abstract: |
Results of Foraminifera assemblage 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 offshore phase, micropaleontology samples were taken from the end of split cores at 5 m intervals. During the onshore phase approximately 2 cubic centimetres of sediment from each of these samples were analysed for foraminifera. After drying overnight in a ~40°C oven, samples were disaggregated in a solution of deionized water, Calgon, and H2O2 to ensure removal of clay-sized particles. Samples were then wet sieved through a 63 μm mesh sieve and rinsed with deionized water. The coarse fraction was placed on filter paper in an oven at ~40°C until it dried completely. […] |

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (fall cone) from IODP Hole 386-M0095A
| 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. […] |
