Near-seafloor optical imagery surveys conducted in 2023 and 2024 across the St. Anns Bank Marine Protected Area, Nova Scotia, Canada: Image annotations of taxa and morphotypes for community composition
Bibliographic record
Abstract
A total of 3381 still images of the seafloor were captured from 41 transects in a survey of the St. Anns Bank Marine Protected Area in August 2023 and 2024. A set of 639 images with a target of 50 m between images were reviewed for the presence of each type of visible taxa. Using the image annotation software BIIGLE, distinguishable organisms were identified to the lowest possible taxonomic level, with some given a morphotype label. Taxonomically, labels for arthropods, chordates, echinoderms, sponges, and other taxa across 14 phyla are provided. A total of 23392 annotations were applied by taxon and morphotype, with image examples for each type provided in an appendix. This report documents the context and use of taxon and morphotype annotations for reference in subsequent community assemblage analyses of occurrences in addition to the preparation for future annotations of abundances of important erect taxa such as crinoids.
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.
