V marci 2025 dosiahol arktick\u00fd morsk\u00fd \u013ead najni\u017e\u0161\u00ed zimn\u00fd rozsah v 47-ro\u010dnej satelitnej hist\u00f3rii.

marca 2025 sa zimn\u00fd rozsah \u013eadu zastavil na 14,33 mil. km\u00b2 \u2014 najmenej, odkedy \u013ead sledujeme zo satelitov. Zima je k\u013e\u00fa\u010dov\u00e1: definuje \u201e\u0161tartovacie podmienky\u201c pre leto.
