Somebody clone Attenborough, quick — the British nature program must continue forever! His latest documentary is Frozen Planet, and all I’ve seen of it is short clips on youtube and various other sites…which just makes me want to see more.
Here is a time lapse video of a brinicle forming: a column of cold water descending from the surface which is saltier than the surrounding sea, so it both sinks and remains liquid as it oozes downward, but it freezes the less briny water around it. It’s slow, but if you’re a slow-moving echinoderm, it’s like the icy finger of a vindictive god reaching down to destroy you.
