Soil properties of ice-wedge pseudomorphs and the encompassing sediments in a recently formed drained basin in Old Crow Flats, Yukon, Canada
Bibliographic record
Abstract
In 2019, a thermokarst lake located in low-shrub polygonal tundra in the Old Crow Flats (Yukon, Canada) drained catastrophically, forming a 1.9km2 drained basin containing a residual pond covering 32% of the basin and corresponding to the deepest parts (2-3 m) of the former lake. In the south-western part of the basin, the youngest part where bank erosion was strongest, a polygonal network was visible after drainage. In the troughs of the polygonal network, ice-wedge pseudomorphs were found in 2022-2023. Ice-wedge pseudomorphs are thermokarst structures that form by the secondary infilling of sediment in deformed cavities left by the melting of ice wedges. The pseudomorphs that were found formed during the expansion of the former lake and differ greatly in composition from the encompassing sediments. This dataset reports the soil properties of seven pseudomorphs and their encompassing sediments (i.e. lake-bottom sediments) that were unearthed at increasing distance from the southwest shoreline to study their composition and morphology.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
