Long-Term Profile and Sediment Morphodynamics: Field Research Facility Case History
Bibliographic record
Abstract
Surface sediment grab samples were collected along one profile line at the Field Research Facility (FRF) at Duck, NC, over a 17.8-month period from March 1984 to September 1985. Profile surveys were taken about every 2 weeks, with sediment samples collected approximately once a month. Extra profile and sediment samples were collected after storms. This comprehensive data set of beach profiles, sediment, and wave and weather conditions provides a unique opportunity to examine natural profile changes and resulting changes in sediment grain-size distribution along the entire length of an active profile and to test and evaluate models of beach profile/sediment interactions to changing coastal processes. Spatial changes indicate that the most active part of the profile at the FRF is the bar/trough area that alternately moves seaward after storms and migrates landward during fair weather wave conditions. The highest variability in sediment grain-size distributions occurred on the subaerial beach and foreshore area.

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.
