Abstract:
This data set includes bathymetry data, seafloor backscatter data and water column backscatter data displayed in Figure 1c-e of Crutchley et al. (submitted for review to JGR Solid Earth, 2020). These data were all collected in 2018 during Research Voyage TAN1808 aboard RV Tangaroa, east of New Zealand. The voyage report describing data collection is located here:
