Benthic diatoms from shallow environments deposited at 300 m depth in a southern Gulf of California basin.
Bibliographic record
Abstract
Benthic diatoms collected with a Technicap model PPS-3/3 trap with an aperture of 0.125 m2 were recorded, which consists of a programmable carousel motorized with twelve 250 mL bottles installed at 300 m deep in Cuenca Alfonso, Bahía de La Paz. The hypothesis that diatoms deposited in the trap sediment would be related to mangrove environments from the Bay of La Paz. Thus, in order to identify the benthic diatoms and infer their origin, a sample for the period December 2011 to January 2012. The identification was made from images taken with a Zeiss Supra Vp55 scanning electron microscope. I know identified 38 diatom taxa, 32 of which were benthic forms including the species: Actinoptychus vulgaris, Halamphora coffeaeformis, Delphineis surirella, Fragilariopsis doliolus and Nitzschia amabilis. What these, the observed diatoms correspond mainly to benthic taxa commonly represented in habitats of shallow intertidal and subtidal zones. Although the hypo- thesis was supported, the species composition of diatoms it did not allow greater precision on the environment of origin.

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.
