Variations in the Labrador Current Transport and Zooplankton Abundance on the NL Shelf by
Bibliographic record
Abstract
Variation in the volume transport of the Labrador Current at the shelf break has important implications for recruitment of calanoid copepods on the continental shelf in the NW Atlantic. During the past several decades the ocean climate on the NL shelf have been characterised by several extremes, from the warm 1960s, cold early 1970s, mid-1980s and early 1990s and the recent warm trend from mid-1990s to early 2000s. As a result of the variations in stratification and the baroclinic currents the volume transport of the Labrador Current at the shelf break also show large interannual variations with an increasing trend in recent years along the Hamilton Bank and Flemish Cap sections. Variations in ocean circulation are hypothesized to influence the distribution and recruitment of zooplankton populations. In this study we focus on the response of the calanoid copepod, Calanus finmarchicus to variations in the volume transport of the LC. Prior to reaching maturity, this species undergoes a transition to deep waters (500 – 2000 m) and a dormancy period during autumn and winter. In order to re-populate the shelf, advective transport of individuals across the shelf-break front from nearby deep slope waters must occur. Our results indicate that volume transport variability of the Labrador Current is significantly correlated with the relative abundance of Calanus finmarchicus, and may impact recruitment of calanoid copepods in shelf ecosystems in the NW Atlantic.

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.
