E. DuVall. Geodetic surveys in Little Placentia Bay (Newfoundland), Bermuda, Bahamas, Jamaica, Cuba, Haiti; 1942 surveys between Panama and Colombia, off the Galapagos and Cocos Islands; Norfolk repairs from 1942-11-21; Caribbean and Panama/Colombia/Ecuador coastal surveys 1943; reclassified AGS-4 on 1943-12-01; arrived Pearl Harbor 1944-01-06 with Service Force Pacific Fleet; survey ship at Kwajalein and Majuro (1944-02-04 to 04-02), Saipan (1944-07-22 to 10-04), and Okinawa (1945-04-18 to 09-02), where she helped rescue survivors of Montgomery (DM-17) and PC-1603; remained off Okinawa until 1945-11-03; arrived San Francisco 1945-11-29; sailed 1946-02-17 for Bikini Atoll for preliminary Operation Crossroads surveys and continued post-test surveying, returning 1946-10-19; departed San Francisco 1946-11-23; decommissioned Norfolk 1947-01-31; transferred to the Maritime Commission 1948-06-09.

- Finding
- USS Bowditch (AGS-4) is one of the 121 non-target support ships for which this Nuclear Test Personnel Review (NTPR) volume provides an information summary, a history of ship movements, and a reconstructed film-badge radiation dose for personnel at Operation Crossroads. This is a ship-specific federal exposure-reconstruction record: the hull sits inside a formal government dose-assessment program.

It demonstrates that ship-level personnel exposure records for Bowditch exist in the federal archive.

- asbestos_application
- Finding
- Peer-reviewed historical study documenting that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII and that wartime demand drove unprecedented asbestos utilization in American yards. Bowditch's documented U.S. Navy yard periods - the 1940 Norfolk Navy Yard conversion, the 1941-1942 Norfolk refit/repairs, and the January-February 1946 Mare Island availability - fall within this documented regime.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming USS Bowditch (AG-30/AGS-4) or MS Santa Inez was found in the public sources searched. Web litigation sweeps (ship name plus hull numbers, 'asbestos', 'lawsuit', 'mesothelioma') returned no qualifying case. IMPORTANT LIMIT ON THIS NEGATIVE: the CourtListener API was rate-limited (HTTP 429, 125/day quota exhausted by other sessions; ~12.5 h to reset) and the CourtListener web UI returned 403, so the systematic docket-level name search prescribed for this batch could not be executed; Google Scholar case-law search was also bot-blocked. The no-litigation result is therefore a partial negative, not an exhaustive one.

- Absence of a located public record does not prove absence of asbestos aboard - a 1929 hull that passed through three documented wartime-era U.S. Navy yard availabilities and was scrapped in 1959 is era-consistent with retained asbestos-containing materials. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility. CourtListener/Scholar blocks leave residual unexamined docket risk.

- Finding type
- historical_record
- Finding
- Source discrepancies resolved: (a) Okinawa departure - a widely mirrored DANFS transcription (hazegray/losthistory) reads 'remained off Okinawa until 3 November 1946', but the authoritative NHHC text reads 1945, consistent with NavSource's occupation-service dates (1945-09-02 to 11-03) and the Feb-Oct 1946 Bikini deployment; 1945 adopted. (b) Reclassification to AGS-4 - DANFS gives 1943-12-01 and Shipscribe's ship note independently reads 'Ex AG-30 1 Dec 43'; NavSource's 1943-12-11 is the outlier; 1943-12-01 adopted. (c) Build dates - DANFS and MARAD give 1929; Shipscribe's table gives launch 1928-12-20 and its ship note 'completed Mar 29'; the two reconcile as launched Dec 1928 / completed Mar 1929. (d) Struck date - Shipscribe gives 1947-03-05; NavSource lists the date as unknown; carried with single-source flag. (e) Scrap sale - MARAD milestones record Sold 1959-08-07 / Withdrawal 1959-08-19; NavSource's phrasing conflates the withdrawal date with the sale and misspells the buyer as 'Boston Medals Co.' (correct: Boston Metals Co., Baltimore, MD); MARAD adopted, with Shipscribe's 'to buyer 19 Aug 59, scrapped by 21 Nov 60' supplying the delivery/dismantlement tail.
