Source-derived summary

Jagged Island is an island 4 kilometres (2 nmi) long, lying 2 kilometres (1 nmi) east of Dodman Island and 15 kilometres (8 nmi) west of Ferin Head, off the west coast of Graham Land, Antarctica. It was probably first sighted in January 1909 by the French Antarctic Expedition under Jean-Baptiste Charcot, and was charted and named by the British Graham Land Expedition, 1934–37, under John Rymill.

Editorial summary

This brief starts where responsible research should: with the source description of “Jagged Island (Graham Land)” as antarctic island. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA strong orientation record where physical form, institutional use and historical geography need to be read together. The current lead gives the account dated anchors—1909, 1934—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Jagged, Island and Graham can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as antarctic island. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q6122543. Authority coordinates are -65.967, -65.683. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1909 and 1934.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
