TABLE 2.

Proportion of bearded seal stomach content samples collected in the Bering Sea that were found to have domoic acid (DA) by year and fitted logistic regression probabilities by year with 95% confidence intervals (CI). Fewer than three samples were collected in 2018 from the Bering Sea, therefore it was excluded from analysis.
