1. Sites M0084 and M0085 (Basin N3)

   Strasser, M.; Ikehara, K.; Everest, J.; Maeda, L.; Hochmuth, K.; Grant, H.; Stewart, M.; Okutsu, N.; Sakurai, N.; Yokoyama, T.; et al (November 2023, Proceedings of the International Ocean Discovery Program Expedition reports)

   During Expedition 386, a total of five Giant Piston Corer (GPC) system deployments in the northern Japan Trench (Basin N3; Figure F1) resulted in the recovery of cores from six holes at Site M0084 and four at Site M0085 (Figure F2). The water depth was between 7590 and 7603 meters below sea level (mbsl). A breakdown of operational time is reported weekly instead of daily (see OPS in Supplementary material) due to decisions to move between sites based on weather and current conditions. Cores from Sites M0084 and M0085 were acquired during Weeks 2, 3, and 5 of the offshore phase. In total, 149.2 m of cores (Table T1) and 133 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in this focus area. Further operations details, including winch log and inclinometer information, are found for all sites in Coring methodology in the Expedition 386 methods chapter (Strasser et al., 2023a) and in the associated files (see PALEOMAG and WINCHLOGS in Supplementary material).

2. Sites M0092 and M0095 (Basin S2)

    Strasser, M.; Ikehara, K.; Everest, J.; Maeda, L.; Hochmuth, K.; Grant, H.; Stewart, M.; Okutsu, N.; Sakurai, N.; Yokoyama, T.; et al (November 2023, Proceedings of the International Ocean Discovery Program Expedition reports)

   During Expedition 386, a total of three Giant Piston Corer (GPC) system deployments in Basin S2 in the central area of the southern Japan Trench (Figure F1) resulted in the recovery of cores from four holes at Site M0092 and two at Site M0095 (Figure F2). The water depth was between 7697 and 7702 meters below sea level (mbsl). A breakdown of operational time is reported weekly instead of daily (see OPS in Supplementary material) due to decisions to move between sites based on weather and current conditions. Holes at Sites M0092 and M0095 were acquired during Weeks 6 and 7 of the offshore phase. In total, 98 m of cores (Table T1) and 34 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in this focus area. Further operations details, including winch log and inclinometer information, are found for all sites in Coring methodology in the Expedition 386 methods chapter (Strasser et al., 2023a) and associated files (see PALEOMAG and WINCHLOGS in Supplementary material).

3. Sites M0081 and M0082 (Basin S1)

   Strasser, M.; Ikehara, K.; Everest, J.; Maeda, L.; Hochmuth, K.; Grant, H.; Stewart, M.; Okutsu, N.; Sakurai, N.; Yokoyama, T.; et al (November 2023, Proceedings of the International Ocean Discovery Program Expedition reports)

   During Expedition 386, a total of five Giant Piston Corer (GPC) system deployments in the southern Japan Trench focus area (Figure F1) resulted in the recovery of cores from six holes at Site M0081 and four at Site M0082 (Basin S1) (Figure F2). The water depth was between 7989 and 8023 meters below sea level (mbsl). A breakdown of operational time is reported weekly (see OPS in Supplementary material) due to decisions to move between sites based on weather and current conditions. Sites M0081 and M0082 were cored during Weeks 2 and 5 of the offshore phase. In total, 154.455 m of cores (Table T1) and 90 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in this focus area. Further operations details, including winch log and inclinometer information, are found in Coring methodology in the Expedition 386 methods chapter (Strasser et al., 2023a) and associated files (see PALEOMAG and WINCH LOGS in Supplementary material).

4. Site M0090 (Basin C1)

   Strasser, M.; Ikehara, K.; Everest, J.; Maeda, L.; Hochmuth, K.; Grant, H.; Stewart, M.; Okutsu, N.; Sakurai, N.; Yokoyama, T.; et al (November 2023, Proceedings of the International Ocean Discovery Program Expedition reports)

   During Expedition 386, two Giant Piston Corer (GPC) system deployments in central Japan Trench Basin C1 (Figure F1) resulted in the recovery of cores from four holes at Site M0090 (Figure F2). The water depth was between 7445 and 7450 meters below sea level (mbsl). A breakdown of operational time is reported weekly instead of daily (see OPS in Supplementary material) due to decisions to move between sites based on weather and current conditions. Holes at Site M0090 were cored during Weeks 6 and 7 of the offshore phase. In total, 55.764 m of cores (Table T1) and 6.8 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in this focus area. Further operations details, including winch log and inclinometer information, are found for all sites in Coring methodology in the Expedition 386 methods chapter (Strasser et al., 2023a) and associated files (see PALEOMAG and WINCHLOGS in Supplementary material).

5. Site M0093 (Basin C/N1)

   Strasser, M.; Ikehara, K.; Everest, J.; Maeda, L.; Hochmuth, K.; Grant, H.; Stewart, M.; Okutsu, N.; Sakurai, N.; Yokoyama, T.; et al (November 2023, Proceedings of the International Ocean Discovery Program Expedition reports)

   During Expedition 386, one Giant Piston Corer (GPC) system deployment at Basin C/N1 in the boundary area between the central and northern Japan Trench (Figure F1) resulted in the recovery of cores from two holes at Site M0093 (Figure F2). The water depth was 7454 m below sea level (mbsl). A breakdown of operational time is reported weekly instead of daily (see OPS in Supplementary material) due to decisions to move between sites based on weather and current conditions. Holes at Site M0093 were cored during Week 7 of the offshore phase. In total, 26.91 m of cores (Table T1) and 3.89 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in this focus area. Further operations details, including winch log and inclinometer information, are found for all sites in Coring methodology in the Expedition 386 methods chapter (Strasser et al., 2023a) and associated files (see PALEOMAG and WINCHLOGS in Supplementary material).
