Cape Polar Star (73°38′S 169°40′E) is a bold cape which forms the southwest extremity of Coulman Island in northwestern Ross Sea. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1987 after USCGC activities in Antarctica, including the Ross Sea, since Operation Deep Freeze, 1978. A survey of this feature was conducted from Polar Star in 1986.

Editorial summary

This brief starts where responsible research should: with the source description of “Cape Polar Star” as cape in Antarctica. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1987, 1978, 1986—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Cape, Polar and Star can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as cape in Antarctica. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 18, 2026. The linked authority identifier is Q2603849. Authority coordinates are -73.625, 169.684. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1987, 1978 and 1986.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
