Two efforts: a 2008-2014 time series of 310 sorted samples (A. Klemmedson, 2015) yielding 24 M. magister megalopae from 14 samples, and a 1949-2009 master sorting log of 2,011 archived samples (E. Jones, as of 2012-02-15) recording which had been examined. Spring cruises, CalBOBL oblique tows, lines < 80 / stations < 90. Counts are occurrence in the examined aliquot, not standardized density. Sorting was performed at the SIO Pelagic Invertebrate Collection, where the removed megalopae are archived in vials. One row per observation: a measurement of one quantity at one event, taxon and depth. `measurement_type` names the quantity and `measurement_value` holds it, so filter on measurement_type.
