Records of munitions dumped in the Irish Sea

Is there a list of conventional and chemical munitions dumped in the Irish Sea?

Yes, but archival and government lists are starting points rather than perfectly reliable inventories.

A list exists in the UK National Archives, with British and Irish government reports offering additional starting points. The panel warns that loading and dumping practices may not match the paperwork, so official totals should be checked against archaeological and environmental evidence. The number of recorded dumping voyages does not comfortably match the theoretical quantity assigned to the site, even allowing for incomplete loads. British and Irish reports are therefore documentary baselines rather than final inventories of what lies on the seabed or later washes ashore.
