I missed the "Ｗ[sK]" addition in the last edit. I don't think it should be here - better to add ダブル as an [sk] reading to the Ｗ/ダブリュー entry. For this entry, Ｗ only (possibly) applies to sense 1 and its presence is screwing sentence linking. I'll drop it, reopen, and propose ダブル for addition to the ダブリュー entry.

北極圏	102432
北極地方	2282

地方 and 圏 don't seem like much of a distinction, the xref is way more common. Reverso commonly glosses this as "the arctic" (also "arctic region", also 北極地方の as the adj. "Arctic").

xref can also be "arctic region" if one likes:
https://context.reverso.net/translation/japanese-english/北極圏#region

I don't know what an adjective is anymore after my previous spiel. I can't see why this should be [adj-no], while 北極圏 isn't.  With の, both will become "arctic" in English, and both will mean "belonging to the region of the north pole" in Japanese. 地方 alone is not [adj-no], and we have *many* entries ending with 地方 that are just [n].

That said, I know "arctic" and "antarctic" would be quite common glosses in English, and I don't mind at all if this is marked [adj-no].
But if so, I think 北極圏 should be as well. (same issue for the south-pole equivalent entries).

I think all adj-f kango words are technically nouns (adj-f is just a PoS we use for convenience).
Given that this is almost always prenominal, I think adj-f is fine.
