Midwater cephalopods in the western North Atlantic Ocean off Nova Scotia
Bibliographic record
Abstract
The midwater fauna off Nova Scotia was sampled with large pelagic trawls over bottom depths of 169–4800 m on seven cruises between August 1986 and June 1989. We identified, counted, and measured mantle length (ML) of all 3661 cephalopods collected on these cruises. These specimens comprised about 63 species in 28 families. The ten most abundant families were (in rank order) Ommastrephidae, Enoploteuthidae, Pyroteuthidae, Histioteuthidae, Brachioteuthidae, Cranchiidae, Mastigoteuthidae, Octopoteuthidae, Onychoteuthidae, and Alloposidae. Although Illex illecebrosus was the most numerous species (1156 specimens in 54 samples), Abraliopsis hoylei (679 in 90, respectively), Histioteuthis reversa (164 in 72), and Pterygioteuthis gemmata (327 in 69) were collected more frequently. Large squids collected here include 3 cranchiids, Teuthowenia megalops (max. ML = 370 mm), Galiteuthis armata (308 mm), and Taonius pavo (300 mm), as well as mature female Gonatus fabricii (275 mm) and Illex illecebrosus (235 mm). Among the 47 species with <10 specimens, noteworthy examples include Chiroteuthis joubini, Chiroteuthis capensis, Joubiniteuthis portieri, Histioteuthis meleagroteuthis, Pholidoteuthis boschmai, Lepidoteuthis grimaldi, Heteroteuthis dispar, Vampyroteuthis infernalis, and Stauroteuthis syrtensis.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
