On a complete tangent: there's a drawing of an iceberg halfway through the article, the typical vertical shape with 10% above the surface. It turns out that icebergs don't float that way; they rotate until they are mostly horizontal. It's one of those things that once I found out, I see wrong icebergs everywhere.

For details, read the article https://axbom.com/iceberg/ and try the iceberg simulator https://joshdata.me/iceberger.html or read the tweet that started it https://xcancel.com/GlacialMeg/status/1362557149147058178
