Ichthyoplankton Abundance and Distribution Model within the Gulf of Maine from Cape Sable, Nova Scotia to southern Massachusetts
Bibliographic record
Abstract
The National Marine Fisheries Service's Northeast Fisheries Science Center conducted standardized ichthyoplankton surveys from 1977-1988 along the continental shelf between Cape Hatteras, North Carolina and Cape Sable, Nova Scotia. These data were collected as part of a comprehensive fisheries ecosystem study to identify changes in fish community structure and investigate recruitment mechanisms. During this time period 25,000 bongo samples were collected within this broad area. In this analysis, a subset of the data were used to model ichthyoplankton abundance and distribution within the Gulf of Maine from Cape Sable, Nova Scotia to southern Massachusetts. Overall, 6,406 samples were used to model abundance and distribution within a seasonal time series (Figure 3.2.1). Additionally, samples conducted within Stellwagen Bank National Marine Sanctuary were analyzed to determine species composition abundance within the Sanctuary.

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.
