The meso- and bathypelagic cephalopod fauna of the Gully submarine canyon
Bibliographic record
Abstract
Abstract Four midwater-trawl surveys were conducted during the summers of 2007–2009 and the spring of 2010 to document the meso- and bathypelagic biodiversity of the Gully canyon. These surveys collected 3871 cephalopods of at least 38 species in 22 families. The numerically dominant 13 species and one genus together comprised 90% of the total taken in standard survey sets. Each of those taxa uses the Gully in a different way, including within-family differences for the two cranchids and two mastigoteuthids. Oegopsids of note include Brachioteuthis beanii, which was the most abundant species in summer but entirely absent in March. The cirrate octopod Stauroteuthis syrtensis was collected in large numbers (n = 142) and a wide range of sizes (9–185 mm) suggesting it may complete its life cycle within the canyon. These results expand understanding of the trophic structure in the Gully and establish a baseline for future monitoring of ecosystem change.

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.
