Sedimentation in Expedition Fiord, Axel Heiberg Island, Northwest Territories
Bibliographic record
Abstract
Expedition River which drains 1079 km2 of glaciated landscape on eastern Axel Heiberg Island is advancing 8.7 m/a (averaged since 1959) into Expedition Fiord. This rate is the highest reported in the Canadian Arctic. Bed material is deposited in the fiord by sediment gravity flows down the foreset beds of the delta. Fresh water forms a well-defined overflow on the sea which is not significantly mixed at least 15 km from the river. However, fine-grained suspended sediment (maximum measured concentration 2.24 g/L) flocculates and settles from suspension soon after entering the fiord. As a result, the sea floor near the delta is thickly mantled with rapidly accumulating deposits of very underconsolidated. fine-grained sediment. Beyond 3 km from the delta modern sediment is restricted to a thin cover with isolated pockets of thicker accumulation in depressions.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
