Metadata & completeness
OBIS — Ocean Biodiversity Information System
N(t) = L / (1 + e^{−k(t − t₀)})Forecast = 10% of the 0-yr record. ⚠ No saturation yet, so the carrying capacity L is poorly constrained — treat the logistic curve as a lower-bound scenario.
OBIS records resolved to species level — taxonomic-metadata completeness for marine occurrences.
