Patterns of apparent oxygen utilization and circulation in Barkley Sound, Vancouver Island B.C.
Bibliographic record
Abstract
Oxygen Minimum zones (OMZs) in the world's oceans and fjords have been expanding in recent years (Paulmier and Ruiz-Pino 2009;Zaikova et al. 2009).These "dead" zones can be strongly influenced by circulation patterns.Sills and shallow bathymetry can impede water flow and produce persistent anoxic conditions in enclosed marine settings.Oxygen is a useful tracer of circulation and long and short term processes that can have serious consequences for macrofauna.This is especially important in areas where aquaculture and anoxia are present simultaneously, as in Barkley Sound.Anoxic conditions on the surface and at depth can produce wide spread population decline of macrofauna.Dissolved oxygen was measured in Barkley Sound and Effingham Inlet with the use of a CTD and Winkler titrations.Newer water was found to be near the mouth of the sound with old water near the eastern end, with the oldest water in Effingham Inlet.Trevor Channel was also found to have relatively old water below 50m.Shallow sills in Trevor Channel and Effingham Inlet impede water movement and cause water movement to slow.Imperial Eagle Channel does not a have a shallow sill and water ages in that channel were only a few days old.

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.
