Quantifying biological carbon export for the northwest North Atlantic continental shelves
Bibliographic record
Abstract
It has been suggested that continental shelf systems contribute disproportionately to the oceanic uptake of atmospheric CO 2 , but the magnitude of this flux and the relative contributions of different underlying mechanisms are poorly quantified. A biological continental shelf pump mechanism has been implied; however, the magnitude of this export depends on advective transport of carbon‐rich water off the shelf, a process that is difficult to observe directly. Here we use a physical‐biogeochemical model for the northeastern North American continental margin to estimate the uptake of atmospheric CO 2 , the fraction of this uptake that results from biological processes, and the transport of organic carbon off the shelf. Our results suggest that there is no systematic difference in the area‐normalized CO 2 uptake between the shelf regions and the adjacent deep ocean. The advective transport of carbon‐rich water off the shelf is insufficient to drive a Continental Shelf Pump in this region.

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.
