Data for: The evolution of deepwater turbidity current bedforms in the Huaguang channel-lobes transition zone unraveled by 3D seismic data in the Qiongdongnan Basin, South China Sea

The water depth of thalweg along the flow direction in deepwater channel-lobes transition zone. The water depth (equal to two-way-travel time of seafloor multiplied by half of seawater velocity, 750 m/s) of seafloor was extracted from the 3D seismic data (Fig. 2B). Pathways or drainage network of gravity flows along the CLTZ on the seafloor were carved by Global Mapper. Therefore, it could be clearly shown that the characters and evolution of high resolution bedforms (cell is 12.5 m × 25 m) correspond to depositional elements of CLTZs within the leveed channel system.
