Retrogressive thaw slump process and morphology, Eureka Sound Lowlands, Ellesmere Island, Nunavut, Canada
Bibliographic record
Abstract
Climate change is expected to have a significant impact on arctic regions, most notably in ice-rich permafrost regions. Retrogressive thaw slumps, backwasting resulting from the exposure of ice-rich permafrost, are a prominent thermokarst feature throughout the arctic and are projected to increase in frequency and extent under warming climate scenarios. However, there is limited information on retrogressive thaw slump activity and field observations are complicated by dynamic interactions between morphology and climate. This work attempts to further define these controls to increase understanding of retrogressive thaw slump processes. Spatial variations in headwall retreat indicate energy input and morphological influence on the landform. Morphologic factors such as ice face angles and the nature of ground ice are observed and analyzed for a relation to ice ablation and headwall retreat. Additionally, spatial microclimates are investigated to define the specific energy conditions at the ablating ice face. Analysis indicates that air temperatures in the vicinity of the ice face vary from exterior temperatures in response to solar radiation and wind speed and direction. Periods of high solar radiation and winds originating from upslope of the headwall potentially create a feedback process for headwall retreat.

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.
