Geomorphic Evidence for Late Glacial Ice Dynamics on Southern Baffin Island and in Outer Hudson Strait, Nunavut, Canada
Bibliographic record
Abstract
We here describe glacial geomorphology that sheds light on ice-dynamic conditions during the Noble Inlet advance, a glacial event involving northward ice flow across Hudson Strait and large-magnitude meltwater drainage across Meta Incognita Peninsula at around 8.9 to 8.4 14C kyr BR Through airphoto interpretation and field inspection of key sites we mapped the glacial geomorphology of interior Meta Incognita Peninsula, the postulated terminal zone for northward expansion of ice from Quebec-Labrador during the Noble Inlet advance. A 170-km-long zone of glaciofluvial canyons, washing zones and boulder deltas was traced from Shaftesbury Inlet to Henderson Inlet. This zone reflects initial drainage across Meta Incognita Peninsula at >520 m elevation, followed by ice marginal drainage at progressively lower levels along the southern slope of the peninsula. The ice marginal outline required to explain the glaciofluvial zone is compatible with northward-trending striae previously reported from the southern coast of Meta Incognita Peninsula. A very large flux of meltwater across Meta Incognita Peninsula probably occurred because eastward supraglacial drainage on ice in Hudson Strait was temporarily impeded and steered northward by a raised ice surface level in outer Hudson Strait, induced by an enhanced outflow of ice from Ungava Bay.

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.
