I'd be pretty sure that the eggs were viable, in the sense that they were fertilised prior to the female's release of the egg sphere ... but I'm not so sure whether collecting small samples of the eggs from an egg mass and maintaining them/'incubating' them in some culture environment is a viable proposition.
The first task is to determine what squid species is releasing them; presto, locate, sample & DNA sequence - not a problem (ok, relocating them might be). Moreover, there seem to be two different egg mass sizes, ~ 1 and ~ 2 metres diameter, so in all likelihood we are dealing with eggs from two different species/genera/families of squid (a little more DNA work). It is possible (quite likely) that these huge egg masses belong to something like an ommastrephid squid (eg, Nototodarus, Ommastrephes, or Todarodes), as opposed to Architeuthis (I just don't believe these egg masses are found in 'the right place' for them to belong to Architeuthis), but all of those ommastrephid genera are comparatively small (mantle lengths considerably less than a metre - nothing like Dosidicus) .... I'm at a loss, unless they belong to something like Mastigoteuthis cordiformis (and I don't believe so) or some rather large onychoteuthid squid (like Moroteuthis, and this I don't believe either)). Questions, questions, questions ....
If the DNA/embryological morphology points to the eggs as being ommastrephid then immediately I'd have to rethink my ideas on the 'hypothetical' Architeuthis egg mass size (I thought it might be ~ 2m) - it would have to be colossal. When initially released by the female it might be ~ 2m in diameter, but after some time, sponging up surrounding seawater, it could get to many metres across. Be cool to bump into a 10m egg mass wouldn't it!!! I dream.
So, stage 1 is to collect the samples and get the things on film (pretty much immediately); stage 2 to DNA them and undertake embryological examination to find out what on earth they belong to (pretty much immediately); stage 3, and this is the dream, to keep them live (Tintenfisch, hurry back from the US of A)... though a dream only (and some say pipe). We're going to try all 3 at once.
