picExpedition_Type_pnt == "CalCOFI" (Q02). This replaced a CalCOFI-region bounding box, which was a proxy for the program and was wrong in both directions — see below.zooplankton_tow; the biovolume measurement table is pending from the provider (blocker Q01) and will be added as zooplankton_measurement.graph LR

cat(glue("Read {format(nrow(d_raw), big.mark=',')} tows, {ncol(d_raw)} columns"), "\n")Read 148,129 tows, 20 columns Canonical names from metadata/field_dictionary.csv. Datetimes are built from date (MM/DD/YYYY) + HHMM time (treated as given pending the timezone answer, Q03).
The scope filter is the program, Expedition_Type_pnt == "CalCOFI", not a CalCOFI-region bounding box. The flag is trustworthy: it agrees with "CALCOFI" appearing in EXPEDITION_pnt on all 148,129 source rows, with zero disagreement either way.
The bounding box it replaces was a proxy for the program, and it was wrong in both directions:
| tows | resolve to a CalCOFI cruise | |
|---|---|---|
| in bbox, not CalCOFI — now dropped | 32,719 | 35.5% |
| CalCOFI, outside bbox — now restored | 15,532 | 83.2% |
| CalCOFI and in bbox — kept either way | 66,811 | 81.8% |
The 15,532 restored tows are not coordinate errors — the CalCOFI subset contains zero missing, impossible or NaN coordinates, so Q04’s antimeridian problem lives entirely in the non-CalCOFI holdings. They are the historical grid: 1950s–80s inshore stations, the Gulf of California, and the Baja lines down to 19.9°N. That they resolve to a CalCOFI cruise more often than the average tow (83.2%) is the evidence they belong.
The dropped tows (CWPA Squid Survey, RACER, SOSO, Huntington Beach, CCE-LTER process cruises …) matter more than their count suggests: 11,613 of them carried a cruise_key, but that key is derived from ship + year-month, so a non-CalCOFI cruise sharing a vessel and month with a real CalCOFI cruise was being stamped with it. Dropping them removes false attributions, not just out-of-scope rows.
