attribute	NC_GLOBAL	summary	String	Ichthyoplankton (fish eggs and larvae) collected by bongo and manta net tows on CalCOFI cruises, processed by SWFSC. One row per sampling event, with event-level effort widened into its own columns. Use this for effort and station counting — summing effort over the observation table double-counts it.
