Strasser, M; Ikehara, K; Everest, JD et al. (2025): Shear strength (shear vane) from IODP Hole 386-M0093B
| 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): Shear strength (handheld penetrometer) from IODP Hole 386-M0092D
| 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. […] |

Muthre, M; Naruse, H; Proust, J-N et al. (2026): Grain-size distribution of from different Holes of IODP Expedition 386
| Abstract: |
This dataset provides grain-size distributions for 278 sediment samples from 11 sediment cores targeting four event beds - Event Bed 1 (CE 2011 Tohoku-Oki), Event Bed 2 (CE 1456 Kyōtoku), Event Bed 3 (CE 869 Jogan), and Event Bed 4 (2.3 ka) - as well as intervening deposits (other event beds and hemipelagic background sediment) from four sites in three trench basins: Basins S3 (site M0091), C1 (site M0090), and C2 (sites M0089 and M0083). These grain-size data were used to build a facies sequence that is applied to identify and interpret event-bed deposition in a hadal trench environment. The sediment cores were collected using a giant piston corer (up to 40 m core length) and a trigger corer onboard R/V Kaimei during International Ocean Discovery Program (IODP) Expedition 386 "Japan Trench Paleoseismology" between 13 April and 1 June 2021.

Strasser, M; Ikehara, K; Everest, JD et al. (2025): Interstitial water geochemistry results of IODP Hole 386-M0089B
| 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): X-Ray fluorescence (XRF) of discrete samples from IODP Hole 386-M0094A
| 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. […] |
