Seasonal Cycle of the Coastal West Greenland Current System Between Cape Farewell and Cape Desolation From a Very High‐Resolution Numerical Model
Bibliographic record
Abstract
Abstract The shelf based West Greenland Current System carries both Arctic Water and Greenland meltwater around Cape Farewell, the southern tip of Greenland, where it may impact the deep water formation in the Labrador Sea. Nevertheless, this current system remains largely unknown due to limited observations. Using a very high‐resolution (1°/60°) numerical simulation integrated from 2005 to 2014, the annual cycle of the current structure in the vicinity of southern Greenland is analyzed to present the seasonal variability of the West Greenland Current System. A distinct shelf break West Greenland Coastal Current (WGCC) exists for about half the year between Cape Farewell and Cape Desolation, although it merges with the main jet of the West Greenland Current (WGC) in winter and separates in summer. The WGC has three components at Juliannehaab Bight: A shelf component, a shelf‐break component and a main slope jet. The shelf system is most energetic in fall, when the freshwater transport is also the greatest in a range of 25–40 mSv, with a broad transport minimum in spring in a range of 15–25 mSv. The seasonal cycle is strongest near Cape Farewell and weakest at Cape Desolation. The strength of the shelf system decreases as one moves north as water is lost offshore, with strongest transports of 0.61 Sv to the east of Cape Farewell and weakest of 0.41 Sv at Cape Desolation. This decrease in transport between Cape Farewell and Cape Desolation suggests substantial exchange between WGCC and WGC in this region.

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.
