0 1984, by the American Society of I.imnology and Oceanography, Inc The origin of a metalimnetic chrysophyte peak
Bibliographic record
Abstract
A metalimnetic chlorophyll peak (40-70 pg.liter-*) in Jacks Lake, Ontario, was due primarily to a colonial chrysophyte, Chrysosphaerella longispina. The peak was not the result of in situ growth, nor of a passive and progressive accumulation of epilimnetic cells. Instead, a sudden bloom of the algae which occurred in the epilimnion at the end of June, possibly due to excystment, descended rapidly and within no more than 4 days concentrated in a narrow band below the thermocline. There was no net increase in chlorophyll a or cell biomass with time once the population was established in this region. No dividing cells were observed. After about 2 weeks the Chl a concentration at the peak began to decline and the peak disappeared by the end of August. The importance of metalimnetic peaks is greatly exaggerated by the measurement of Chl a. Subsurface chlorophyll maxima are com-mon in many lakes (Eberly 1959; Ichimura

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
