Mesoscale Eddy Transport across the Antarctic circumpolar current: a model-observation comparison
Bibliographic record
Abstract
As part of the Meridional Overturning Circulation, deep waters cross the strong fronts of the Antarctic Circumpolar Current (ACC) to upwell near the Antarctic coast, where they take up large amounts of excess heat and anthropogenic carbon from the atmosphere.Until recently, studies quantifying cross-frontal transport in the Southern Ocean have been mostly carried out with numerical models as observational data were too sparse in this region.Modelling studies have shown that mesoscale eddies are the main agents for the southward mass transport across the fronts of the ACC above major topographic sills.Recently, the number of measurements collected by the Argo array of profiling floats has become sufficient to allow reconstruction of eddy transport across the ACC.This study examines the transport of mass across the Polar Front, calculated between the surface and around 2 km depth from control simulations of a suite of climate models differing solely in the resolution of the ocean component (1 • , 0.25 • , 0.1 • ).These transports are
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
