Abstract
Abstract Palynomorphs are acid-resistant organic particles which behave aerodynamically and hydrodynamically like silt, and which resist degradation except in oxidizing or highly alkaline conditions. They are present in virtually all marine sediments, from the tropics to the poles and from estuarine to abyssal environments. Reconstructions of Quaternary sea level in cores from the New Jersey shelf (ODP Hole 1072A) and slope (ODP Hole 1073A) based on the modern distribution of palynomorphs across the New Jersey margin as well as the taphonomic alteration of palynological samples agree fairly well with data from other available proxies (e.g., oxygen isotopes). The palynological signatures of sediments on continental margins also provide information about the generation of sequences and sequence boundaries. The palynological character of surfaces identified as sequence boundaries from seismic reflection profiles records the generation of erosional unconformities during extreme lowstand events that altered the geometry of the margin. Very low palynomorph concentrations and presumably oxidized palynological assemblages (containing few protoperidinioid dinocysts or thin-walled pollen grains) characterize erosional unconformities. The strong seismic reflection associated with sequence boundaries results from physical contrast between the transgressive/highstand sediments (with very high palynomorph concentrations, P:D values declining rapidly upcore, and Pinus-dominated pollen assemblages) and underlying the lowstand sediments (with low palynomorph concentrations, high P:D values, taphonomically altered and ecologically mixed palynological assemblages). The palynological content of Quaternary sediments at ODP Sites 1072 and 1073 thus supports the role of eustasy as an important factor in shaping the New Jersey margin.

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 it
