    is it possible to pin a radio transmitter to an archi?

    sadly i missed the discovery program where steve caught those youngsters(no cable),but having bumped into that info via googlesearches, i got to thinking that a catch,tag,release program could provide substantial data.

    Howdo ubiquity.

    Indeed this is the plan. We couldn't grow the little guys up to maturity (we couldn't afford to feed or accommodate them), so we were going to release them with little transmitters attached. It is still the plan.

    Cheers

    Hello Ubiquity,

    I was going to submit an involved answer to your question, but...

    That's alright Clem - your answer was so much more informative than mine :D If you ever want a job then sing out.

    Other things planned ..... hmmmmm.
    Cheers

    have these difficulties that clem mentions been dealt with? is it going to be as problematic as all that?

    heavens...i hope not!

    Steve,

    Double Dang.

    Where will you embed the transmitter? Statolith? Mantle wall?

    Job?

    i have a feeling i'm about to be extremely jealous of good ole clem here!

    ahhhh who am i kidding...all i have is an art degree...
    ever get the feeling that you missed your calling? i should be out on a boat with you guys! that would be soooo awesome!

    Ja, probably slip it in (looped through) the mantle somewhere up front (just behind the head, dorsally, with disolving link/thread), but I really hadn't taken the idea too far - the little sods went and died on me :( . There'll come a time I'm sure (cannot give up now eh!).

    I think we'll crack this keeping squid live in captivity within the next four-or-so months (the plan).
    Cheers

    Ubiquity, anyone is welcome to tag along with us - biology degree, art degree or no degree (I like people with art degrees - they tend to be a bit more balanced than .... urrrrr .... myself). Just tell me when to pick you up from the airport.

    Apologies. Seems my phantom post is irretrievable (unless you've still got it). I'm happy that those "formidable obstacles" I went on about aren't insurmountable.

    Yours truly,

    Clem

    will the little guys be tracked by satellite,or by something a little more mundane?
    assuming that the transmitter is good for the long haul,it seems just too wonderful an idea that we'd be able to follow archi wherever he went and eventually catch up to him and study his behavior and..and..and...oh my! looks like somebodies getting a little too excited here!

    here's a thought...the transmitter could be a homing beacon for a robotic sub that would follow the subject wherever it went.

    i'm getting ahead of myself again aren't i? :)

    Probably the greatest obstacle we face right now is raising the dollars to do this (go out looking for the larval giant again). Then there's the concern in my mind that the year we decide to do it (or raise the funds to do it; 2004 is the plan) that it will be an extremely poor year as far as larval recruitment is concerned; for this reason we propose to do both adult and larval searches.

    This past summer has been positively shocking as far as adult Architeuthis captures are concerned (not necessarily a bad thing, as far as conservation of the species is concerned), but for years people have said Architeuthis occurs in abundance some decades, then disappears for several more (only one specimen caught this past summer, to my knowledge; normally we'd get 10+). Has this finally happened - the near-decade of plenty has passed and we're now into famine? We've certainly had a record number of captures in recent years (the past 8 years). I don't think so (or hope this isn't the case), but 2003 would have been a lousy year to go looking for the larva (= paralarva) if the number of adults caught is anything to go by.

    It would be hard showing your face in public if you went out and caught zip second time around.
    Cheers

    You're very quick to post ubiquity - keep on sneaking in there.

    No, you'd not be able to do it by satelite (or at least I don't believe you could). You'd have to have 3-or-so receivers in the water and plot its movement/position by triangulation (or something like that ... my brain isn't functioning too well this evening). I don't think it would hang around in one place too long, so after sticking your buoys in the water you'd lose the squid within minutes, unless you could move those buoys/transmitters, or had a truckload of them in the water so that you didn't have to lift them all the time. If it escaped your path of transmitters you'd not know what happened to it (or where it got to) until the dissolving link on the transmitter broke and the buoyed transmitter floated to the surface (you could then work out how far it went between release and weak-link dissolving, but it's not telling you an awful lot).

    O
