These data are gridded seismic reflection horizons that represent 1) the base of an interpreted mass transport deposit and 2) the base of the gas hydrate stability zone in sediments. Horizontal dimesnions are in metres, while the vertical dimension is in seconds two-way travel time. The horizons were generated during 2020, using the Kingdom Suite software (version 2019). The data are interpreted products based on seismic data from Research Voyage TAN1808 aboard RV Tangaroa. They are provided here as space delimmited ascii files.
Format x y t (space delimeted ascii file, where "t" is two-way time in s).
