Based on the in situ seismic profile data collection in the Heihai Lake of the Qinghai-Tibet Plateau in 2011, the sub-bottom seismic dataset was developed, using the mean curve method integrating the optimized transform sliding time-window energy ratio technique. The dataset is consisted of three parts: (1) geolocation data of the Heihai Lake of the Qinghai-Tibet Plateau; (2) in situ data collected in summer of 2011, including the data covering three profiles, they are 3sn profile (3001 samples), 4ns profile (1918 samples) and 4we profile (8001 samples). 1664 in situ data collected in each of the 12,920 samples total; (3) the analysis data by energy ratio technique in tables, including table 1: the boundary lines of 3sn profile in the Heihai Lake; table 2 profile data of single seismic and energy ratio value of 19 rows; table 3 Parameterization scheme(Lmin-Lmax/Lwin) and the number of the extracted boundary points; table 4 The extracting effects with the different Lwin, under the skeme of Lmin-Lmax; and table 5 single seismic profile data of Heihai and Xiyang. The dataset is archived in .kmz, .shp, .txt and .xlsx data formats with the compressed data size of 27.7MB. The analysis paper was published in the Journal of Progress in Geophysics (in Chinese), No. 3, Vol. 20 2015, doi: 10.6038/pg20150318.
