2. Site M0091 (Basin S3)

   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 the northern study area (Basin S3) of the southern Japan Trench (Figure F1) resulted in the recovery of cores from four holes at Site M0091 (Figure F2). The water depth was between 7802 and 7812 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 M0091 were cored during Week 6 of the offshore phase. In total, 51.94 m of cores (Table T1) and 53.5 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired, respectively, in the 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. Site M0088 (Basin N2)

   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 at this study area in the northern Japan Trench (Basin N2; Figure F1) resulted in the recovery of cores from four holes at Site M0088 (Figure F2). The water depth was between 7525 and 7550 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 M0088 were cored during Week 4 of the offshore phase. In total, 56.205 m of cores (Table T1) and 49.7 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired 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). Note that inclinometer data were not properly recorded and are therefore not reported for Site M0088.

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 M0086 (Basin 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 this central study area of the northern Japan Trench (Basin N1) (Figure F1) resulted in the recovery of cores from two holes at Site M0086 (Figure F2). The water depth was 7502 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 M0086 were cored during Week 3 of the offshore phase. In total, 19.275 m of cores (Table T1) and 6.65 km of hydroacoustic profiles (see Hydroacoustics) were recovered and acquired in this focus area. An expendable bathythermograph (XBT) probe was deployed at Site M0086 on 2 May 2021 at 0715 h. 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).
