Data were collected using an EM710 multibeam sonar with a vertical resolution of 0.2% of water depth, and a horizontal resolution of 3% of water depth. The sedimentologically active prodelta region was surveyed every weekday, and the distal delta region was surveyed every fortnight. The very shallow water region (< 5 m) of the delta top was surveyed on a semi-weekly basis. We calculated the difference in seafloor elevation between consecutive bathymetric surveys, which are usually 1-day apart, but can be 3-days apart during weekends. We define an event when there is discernible change in seafloor morphology, and subdivide events that affected the southern, central and northern channels on the delta front. When there is change in more than one channel during the same period, these are counted as separate events. The cumulative volume (in metres cubed) and corresponding distance (in metres) data used to produce the plots in Figure 2, Figure 3, and Supplemental Figure 5 of the publication entitled "Which triggers produce the most erosive, frequent and longest runout turbidity currents on deltas?" are provided. Filenames (e.g., ‘f_jd137138s’) are given based on the type of event (‘f’ = landslide and ‘m’ = plume event), the Julian day on which they occurred (‘137138’ means the event occurred between Julian Day 137 and 138). The letter at the end of the name corresponds to the channel in which the event occurred (‘n, c, s’ corresponds to north, central and south channel). These data were collected to explore the evolution of turbidity currents on the sandy prodelta region of a rapidly prograding river delta by looking at cumulative seafloor change, extracted from bathymetric difference maps.
