Biomarkers as Sea Ice Tracers for the Western Canadian Arctic
Bibliographic record
Abstract
This project aims to retrace the glacial evolution of the Western Canadian Arctic by quantifying biomarkers in sediment cores. Biomarkers serve as a proxy to derive the amount of sea ice from the sediment record. This project involves the delicate chemical extraction of ice cover biomarker IP-25 and ice free biomarker Brassicasterol to generate a ratio, PIP-25 (percent of IP-25 to Brassicasterol), approximating sea ice cover within a certain time period. This groundbreaking research is the first of its kind in the Canadian Arctic, and the sediment core recovered this past August is the first ever from the region (M'Clure Strait). MacEwan University has exclusive access to this sediment core. This project is important to international research, as the M'Clure Strait has never been examined geologically. This research can elucidate the ice sheet development of the region, which connects the Arctic Ocean with the Atlantic through the Northwest Passage, crucial to oceanography research.

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.
