Dune morphology response to water level change, Pinery Provincial Park, Ontario, Canada
Bibliographic record
Abstract
This thesis describes the geomorphological changes to a trough blowout in Pinery Provincial Park's sand dunes. The Park is located on Lake Huron’s southeastern shore where, due to rapid changes in Lake Huron water levels, a study could be completed examining the changes to blowout morphology based on the change in beach sediment supply. The study took place during relative low Lake Huron levels (1999-2000) and was compared to data collected during a period of relative high Lake Huron levels (1994-1995). Field research included erosion pin measurement to monitor and verify morphological change through the throat of the blowout, aeolian sediment trap volume measurements and grain size analysis, and three-dimensional mapping to calculate areas of erosion and deposition by volumetric analysis. Erosion occurred through the blowout throat during both study periods but less so during the low lake level study period. The increased beach sediment supply provided a catalyst for increased deposition landward and lakeward of the foredune ridge during the low lake level period. More beach sediment migrated through the blowout and onto the landward side of the blowout crest during the low lake level period.

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.
