The Changing Behavior of the West Greenland Current System in a Very High‐Resolution Model
Bibliographic record
Abstract
Abstract Analyzing a high‐resolution (1/60°) numerical model over 2008–2018, the inter‐annual variability of the West Greenland Coastal Current (WGCC) on the shelf and West Greenland Current (WGC) at the shelf break is presented. Both currents flow from Cape Farewell and extend to Davis Strait, with their speeds and transports corresponding well with observations. The trend over the study period of the WGCC and WGC strength near southwest Greenland are opposite, with the former declining while the latter strengthened, both by a speed change above 0.1 m/s. Both currents are predominantly buoyancy forced, but wind forcing becomes more dominant approaching Davis Strait. The main exchanges from the two currents with the interior of the Labrador Sea occur between Cape Desolation and Fylla Bank. The net volume, freshwater, heat transport decreases between these two sections are 1.4 Sv, 13 mSv, 36.7 TW, respectively. The freshwater transport of the WGC itself does not drop in between these sections, receiving freshwater from the WGCC to compensate for the losses to the basin interior. Thus, we see significant freshwater (83.1 mSv) and heat transports (70.7 TW) of the WGC remaining at Fylla Bank that reach the northern basin instead of being fluxed into the interior of the Labrador Sea. This suggests that the exchange between the boundary current system and the interior is more limited than previously thought, and most of the Greenland and Arctic melt reaches the northern Labrador Sea. Our results highlight the importance of resolving the WGCC and shelf processes.

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.
