- Population
- USS Carnelian crew and ship operations
- Limitations
- The deck-log catalog record documents the vessel and service-period record, not asbestos, insulation, materials, individual work assignments, exposure, or disease. The production brief's 30 June 1945 endpoint is carried as the qualifying wartime-service scope; the catalog title extends to 1 January 1946.

[5]National Archives, Information NOT Included in Deck Logs [other_primary]
- Locator
- Sections on shipyard work/materials and individual work assignments
- Finding type
- asbestos_application
- Finding
- The National Archives states that a deck log may show when a ship was moored or dry-docked but does not identify the work performed or the materials used, and does not record day-to-day work assignments of individual crew members.

- Navy deck-log records and ship personnel
- Limitations
- This source explains why Carnelian's deck logs cannot prove asbestos aboard, asbestos-containing products, individual exposure, or causation. It is a limitation and negative finding about the record type, not proof that asbestos was absent.

- Population
- USS Carnelian (PY-19)
- Limitations
- This is a bounded research negative, not proof that asbestos was absent from the vessel. The NHHC DANFS page was unavailable at research time, and the CourtListener sweep did not return completed JSON because the authenticated helper was stalled by the shared fleet limiter; both gaps remain open.
