Source-derived summary

The Zélée Subglacial Trench (68°0′S 144°0′E) is a subglacial valley on George V Coast, running north-northeast to south-southwest and coinciding with the trough cut by the Mertz Glacier. The feature was delineated by the Scott Polar Research Institute (SPRI)-NSF-TUD airborne radio echo sounding program, 1967–79, and named after the corvette Zélée (Lt. Charles Jacquinot) of the French expedition of 1837–40 under Capt. Jules Dumont d'Urville.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as subglacial valley on George V Coast off 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 Apr 12, 2025. The linked authority identifier is Q8068721. Authority coordinates are -68.000, 144.000. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1967 and 1837.

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.
