@farmerman,
Yes, definitely a boffin ship. The blue link takes you to their blog page and there is a lot of mention re. dropping various data recording buoys, even one which has automatically opening and closing bottles on the way down, to take samples at different depths.
My offspring is making up the numbers when he goes, as the ship doesn't yet have a license to carry and use a fluoroscope yet (isotope carrying license, apparently) so he will be simply presenting his data so far, and basically letting the other boffins know how it is all going. He will then muck in with anything that needs doing, and hopefully do a bit of contact building for the future.
On the few occasions I've actually been at sea with him, he seems pretty good at holding down his breakfast, but a large ferry on the Channel or Bay of Biscay is a bit different to a technologically advanced bucket on the Tasman Sea.
Still, all very good character building stuff.
