Abstract

fetched live from OpenAlex

This publication provides a collection of geoscience and biological information interpreted from seismic shothole drillers' log records. The shothole records provide point lithostratigraphic observations of muskeg and earth materials from surface to 10-20 m depth. Data are presented as GIS, allowing spatial patterns and distributions to be assessed.Bedrock situated at the top of drillers' log records is mapped as outcrop, while that situated below unconsolidated drift is mapped as subcrop. Identification of bedrock type and situation will aid bedrock mapping and drift exploration, particularly in areas of thick drift cover. It will also assist bedrock-generated landslide hazard assessments, and benefit granular aggregate exploration, as competent bedrock such as limestone could be quarried. Geohazards pertain to those records interpreted to represent hazards to infrastructure development, such as roads and pipelines, as well as future geophysical seismic exploration. The geohazards identified include the presence of ice or water at depth, and occurrences of flowing holes (water), flowing sand, and gas. Muskeg thicknesses and/or the presence of muskeg (thickness undefined) was interpreted from drillers' log records and plotted as thickness-proportional symbols. The available data permits broad trends in muskeg thickness and distribution to be discerned throughout the study area, and highlights areas where thick and extensive muskeg could pose a significant concern to future infrastructure development.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
