Abstract

fetched live from OpenAlex

Abstract Airborne electromagnetic (AEM) systems were first developed in the early 1950's in Canada and Scandinavia. AEM systems have been applied in mineral exploration, geological mapping, geohydrological investigation and environmental monitoring in China since the 1980's. A dual-frequency AEM system (463 Hz, 1,563 Hz) which was developed by IGGE in the early 1980's has surveyed more than 160,000 line-km. A new three-frequency AEM system was also developed by IGGE in 1999. In 2001, a survey was conducted in Qian'an, Jilin Province, using the new AEM system. The purpose of this survey was to delineate salinization, to determine the freshwater/saltwater interface and to explore the freshwater resource for catchment management such as drinking, agriculture, stock raising and wetland protection. The main purpose was achieved by this survey. For the salinization study, the upper frequency AEM data were used. By comparing the apparent resistivities calculated from the AEM data with the geohydrological data, the areas and intensity of salinization were identified. For the freshwater resource study, lower and middle frequency AEM data were applied. Two zones of fresh ground-water were determined within the achievable exploration depth (about 100 m) of the AEM system.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
