This data uses a high-precision transient electromagnetic instrument (HPTEM-18) to detect the permafrost in the Kamaran River Basin on the eastern slope of the Greater Khingan Range. The soil profiles of the sample plots are grouped and the relative resistance value distribution corresponding to the profiles is recorded. The data includes: plot number, survey time, longitude, latitude, location, depth (m), and relative resistance value (Ω).
The provider of this data is the School of Geographic Sciences at Harbin Normal University, provided by the Key Laboratory of Cold Region Geographic Environment Monitoring and Spatial Information Services in Heilongjiang Province. The permafrost in the Kamaran River Basin on the east slope of the Greater Khingan Range was detected using a high-precision transient electromagnetic instrument (HPTEM-18), and the data was collected from July 1, 2023 to August 31, 2024.
1. The sample plot should cover typical habitats and be distributed according to gradients (such as altitude and vegetation type). Data collection should take into account representativeness, recording key information such as plot number, collection time, GPS coordinates, etc.
2. The quality controller is fully involved in checking the completeness of records, accuracy of data labeling, and timely correction of deviations.
3. Collection specifications: The data collection frequency is 6.25 Hz, the stacking frequency is 300, the repetition frequency is 2, and the measurement depth is set to 20 m.
4. Use The HPTEM engineering file was set with parameters (constraint coefficient, inversion coefficient, target depth, start and end point numbers, etc.) in the HPTEMData Process software, resulting in a visual resistivity profile and exporting the resistivity data in a tabular format.
