Not me this time (I'm off on 22nd December as things stand), but a good friend is about to do Southampton-Chile on a research cruise. She will be on board working (well, volunteering) for Education Through Expeditions, a new charity aiming to inspire school children through communicating with them about expeditions (scientific and 'true' exploration). It will mean she has done Antarctic, Arctic and the bit in between within 9 months.
Also, for those who like this sort of thing, another, very amusing blog byAlan Jamieson, someone else I've been to sea with, has just ended but is worth a read: http://planetearth.nerc.ac.uk/blogs/story.aspx?id=804 I particularly like the line
"So I tip my imaginary trilby to these fellas for being jolly good sports, and for being so very professional and silly, and for knowing exactly when to be which."
