This dataset includes multi-channel seismic reflection data (post-stack time migrated seismic sections) that were collected in 2018, during Research Voyage TAN1808 aboard RV Tangaroa, east of New Zealand. These are the data we present in Figures 4,5,7 and 9 of Crutchley et al. (submitted for review to JGR Solid Earth, 2020). The voyage report describing data collection is located here:https://www.gns.cri.nz/Home/Our-Science/Energy-Futures/Gas-Hydrates/Recent-Expeditions/HYDEE-I-TAN1808/TAN-1808-report-2018Multi-channel seismic reflection data from APB13 survey, collected by Anadarko Petroleum Company, in 2013. We have re-processed data from Line APB13-25, and have displayed industry processing of Line APB13-32. The data provided correspond to data shown in Figures 2,3 and 7 of Crutchley et al. (submitted for review to JGR Solid Earth, 2020).Multi-channel seismic reflection data from Voyage SO214 aboard RV Sonne in 2011. The voyage report is available here: http://dx.doi.org/10.3289/ifm-geomar_rep_47_2011The data are displayed in Figure 9 of Crutchley et al. (submitted for review to JGR Solid Earth, 2020).
