Bibliographic record
Abstract
Seamounts are oases of life within the deep sea. Recruitment mechanisms to these isolated systems, where benthic larvae spend weeks or months in the pelagic, remain a mystery. Persistent closed circulation patterns ('Taylor cones') are proposed to increase local retention around these underwater mountains, but the idea remains controversial. Some coral species may help us understand this puzzle. Cold-water corals, such as Primnoa pacifica and Parastenella spp., grow slowly, orienting their fan perpendicular to, and curved towards, the mean-flow direction. We took advantage of these long-term natural current meters, using a combination of benthic imagery, sea-surface height, Argo trajectory, hydrographic, and reanalysis model data to examine flow around S G _ áan K _ ínghlas-Bowie Seamount (S K _ -B) in the Northeast Pacific. We found that corals living on the seafloor on all sides of the seamount experienced a north to south flow (opposite to regional circulation), showing no evidence of a persistent closed circulation. We suggest that a combination of remotely generated internal tides breaking on the plateau and steering/rectification of local tides below 500m could cause these strong coherent bottom currents. Finally, we also observed transient clockwise circulation around the seamount when Haida Eddies became trapped. Eddies provide a regular mechanism for larval and food transport from the coast to S K _ -B. Once trapped, the closed clockwise circulation lasts months and likely aids in local retention and self-recruitment. Our findings reveal the dynamic nature of flow over seamount-like features and the importance of understanding this complexity in the broader context of marine conservation. • Coral orientations show uniformly directed long-term near-bottom flow on a seamount. • Flow direction is contrary to basin-scale circulation and presence of Taylor cone. • A Haida Eddy over the seamount caused Taylor cone-like circulation of >5 months. • Altimetry shows Haida Eddies run into the seamount yearly carrying shelf materials.

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.
