Abstract

fetched live from OpenAlex

A finite element circulation model of flow was constructed for Sungo Bay, China, a site of dense cultivation of both marine bivalves and kelp, to assess the magnitude of friction due to culture structure and its implications for particle exchange. In the model, parameterization of friction was modified to reflect the patterns of culture configuration in the bay and the results compared with the default case with no culture. Results of model output indicate that suspended aquaculture results in a 20% reduction in current speed in the main navigation channel and a 54% reduction in speed in the midst of a culture area. In the channel, reduced flow had little effect on tracer exchange under mid-ebb conditions, but the presence of culture structure caused a 41% decrease in exchange rate compared with the absence of culture. These results indicate that disregard for physical barriers associated with culture will result in a serious over estimation of the particle renewal term and thus an overestimation of carrying capacity. Further work is required to measure the characteristics of culture (spacing, length scale), quantify their magnitude of flow retardation in the field, and improve model parameterization of the frictional effects of various types of culture.

Full frame distilled prediction

Teacher imitation

Not 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.
