Field observations of iceberg deterioration
Bibliographic record
Abstract
An investigation into iceberg evolution is reported. The main focus of the work was a unique field observation program in which photographs were taken of two grounded near shore icebergs over a period of several days each. In addition to the photographic observations of the above water portion of the icebergs, underwater sound recordings were made periodically. Sound records include a large cracking event in which the iceberg calved. The results of the field program are presented, including some specific local wave erosion data. This is part of an ongoing effort to understand the physical processes involved in iceberg evolution. The work reported here was done under two separate contracts let to university based researchers: 391134 Iceberg Evolution Model - Wave Accelerated Erosion, and 391137 Iceberg Evolution Model 舑 Field Observations. Both contracts dealt primarily with gathering field data, the former concentrating on visual information and the latter on acoustic data, so a common field program was mounted and the results are documented jointly.

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.
