Wyville Thomson Ridge
submarine mountain range
The Wyville Thomson Ridge is a bathymetric feature of the North Atlantic Ocean floor ca. 200 km in length, located between the Faroe Islands and Scotland. The ridge separates the Faroe–Shetland Channel to the north from the Rockall Trough to the south. Its significance lies in the fact that it forms part of the barrier between the colder bottom waters of the Arctic and the warmer waters of the North Atlantic.
The Wyville Thomson Ridge is named after Charles Wyville Thomson who pioneered the first exploration of the area.
Geology
The Wyville Thomson Ridge, and the smaller but similar Ymir Ridge, form the northern boundary to the Rockall Basin, a mainly Mesozoic rift structure. The current form of the ridge is an anticline with up to 2 km of amplitude, formed by a period of shortening during the Eocene to Miocene period. This fold is interpreted to have formed by the reactivation of a pre-existing fault, and is, therefore, classified as an inversion structure.
Begin with the source’s own compact description: “Wyville Thomson Ridge” is submarine mountain range. The dossier treats that line as a proposition to test through Wyville, Thomson and Ridge, not as a finished interpretation.
Why this record matters
The phrase “submarine mountain range” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Sep 17, 2026. The linked authority identifier is Q1371811. Authority coordinates are 60.130, -7.600. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.
