Mapping and name
The Bear Peninsula was first delineated from aerial photographs taken by the United States Navy Operation Highjump in January 1947.
It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) after the ice-ship USS Bear, flagship of the USAS, from which three reconnaissance flights were made in late February 1940, resulting in the discovery of Walgreen Coast (with probable sighting of this feature) and the Thurston Island area.
This ship, under the name Bear of Oakland, also served as flagship of the Byrd AE, 1933–35, which based at the Bay of Whales, Ross Ice Shelf.
This brief starts where responsible research should: with the source description of “Bear Peninsula” as peninsula in Antarctica. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as peninsula in Antarctica. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q2646673. Authority coordinates are -74.583, -111.000. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 1940 and 1933.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
