Population structure of three dominant Calanus species in North Water Polynya, Baffin Bay
Bibliographic record
Abstract
The population structures of Calanus finmarchicus, C. glacialis and C. hyperboreus were investigated in the recurrent polynya of the North Waters (NOW) in Baffin Bay during April-July 1998. Species were determined from samples collected by plankton nets of 300 µm and 200 µm mesh size. The highest concentration of all three spe− cies was found at the centre of study the area. C. hyperboreus was the most abundant spe− cies (44.54 ind. m -3 ). C. glacialis was recorded up to 27.14 ind. m -3 , C. finmarchicus up to 5.63 ind. m -3 . C. finmarchicus was reproducing in the northern end of Baffin Bay. The life cycle for C. glacialis was estimated at 2 years, and that of C. hyperboreus to last at least 4 years.

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.
