Investigation of construction and maintenance of airdromes on ice, 1946-1947 : report of landings on ice at Cambridge Bay, Canada, May 1947
Bibliographic record
Abstract
Field observations were made of the operation of wheeled aircraft from water supported ice at Cambridge Bay, Victoria Island, Canada for "Project Beetle", in connection with an "Investigation of the Construction and Maintenance of Airdromes on Ice Caps and Ice Masses" as authorized by Office, Chief of Engineers and carried out by the New England Division during the fiscal year 1946-1947. The observations were made from 14 May 1947 to 24 May 1947. The site of operations had been selected as a location for one of a number of joint Canadian and American Arctic weather stations. Observations and studies were made as follows: (1) Effect of airplane wheel loads on ice, (2) Effect of snow cover on operation of wheeled aircraft on ice, (3) Effect of weather on ice formation, (4) Effect of operation of construction and maintenance equipment on ice surfaces, (5) Effect of oil, gasoline and debris on ice surfaces, (6) Construction and maintenance of snow covered ice airfield. It is concluded that fast ice in sheltered bays and inlets, such as that at Cambridge Bay, provides one of the most desirable sites for ice airfields when ice thickness requirements can be met. It is also concluded that 4 to 6 inches of snow cover on traffic areas is desirable for prolonging the useful period of operation, for smoothing out of minor surface irregularities and for providing a satisfactory braking surface for aircraft wheels.

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.
