Lake abundance, potential water storage, and habitat distribution in the Mackenzie River Delta, western Canadian Arctic
Bibliographic record
Abstract
The complete landscape surface of the active Mackenzie River Delta (13,135 km 2 ) was manually partitioned into discrete lakes (3331 km 2 ), channels (1744 km 2 ), wetlands (1614 km 2 ), and dry floodplain area (6446 km 2 ) via GIS analysis of digital topographic maps recently available for the system. The census total of lakes (49,046) is almost twice as large as prior estimates. Using this new information, total lake volume in the delta during the post river flooding period is estimated as 5.4 km 3 . Total floodwater storage in the delta lakes and floodplain at peak water levels is estimated at 25.8 km 3 and thus is equivalent to about 47% of Mackenzie River flow (55.4 km 3 yr −1 ) during the high‐discharge period of delta breakup. During this period the stored river water can be envisioned in the form of a thin layer of water (2.3 m thick on average) spread out over 11,200 km 2 of lakes and flooded vegetation and exposed to 24 h d −1 solar irradiance. Consequently, this temporarily stored water has significant potential to affect the composition of river water flowing to the Beaufort Shelf as it recedes to the river channels after the flood peak.

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.
