MAREEL — [Noun] A phosphorescent glow on the ocean's surface, caused by the agitation of bioluminescent marine organisms. From an unattested Norn term *mareld, from Old Norse mǫrueldr, from marr ("sea") + eldr ("fire"). Unlike the vast, spectral phenomenon of "milky seas" or the broad biological category of "bioluminescence," mareel is the sea's own intimate, ephemeral fire. It is the sudden, blue-green flare in the wake of an oar, the constellation of cold stars swirling around a wader's ankles, and the brief, silent meteor shower confined to a single wave's crest—a momentary, liquid defiance of the dark, proving the oldest gloom can be startled into a brief, beautiful answer.
