Woods Hole Oceanographic Institute was (and still is to the best of my

I think they did a paper on the issue, but I'd have to dig for it...

It wasn't too long after though that reports were suggesting earlier
failures than expected, but I can't for the life of me remember why.
Something underwater does come to mind, a long term project that wasn't
perhaps as long term as expected, either way someting went pear shaped,
anyone have any idea of what it was and the current state of play?
