Reinterpretation of oceanic 230Th profiles based on decadal export productivity (2003–2010)
Bibliographic record
Abstract
Abstract Understanding 230 Th distributions in the global ocean is important to support and guide the use of this important radioactive nuclide in multiple aspects of oceanographic research, and this issue is now revisited. Based on estimates of export productivity (EP) over 2003–2010 and assuming 230 Th scavenging at equilibrium at seven Pacific stations where linear 230 Th profiles are found, an empirical equilibrium-state 230 Th-scavenging versus EP correlation is established. This correlation demonstrates the relationship between 230 Th-scavenging intensity and EP in the absence of advection. With this correlation, other 230 Th profiles from global oceans are reinterpreted. My findings provide alternative explanations of signals carried by 230 Th distributions with regard to advection, by a reassessment of the 230 Th deficits in deep waters. Such an equilibrium-state 230 Th-scavenging versus EP correlation provides a basis for convenient parameterization for use in 3D modeling studies of the 230 Th distributions.

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.
