Alvin is in house at WHOI and I am pretty sure they are having an open house to the public on this Sunday for anyone that wants to go and see it up close. If you are into that type of thing it is pretty neat. I was told it is going to be stripped down after one more excursion and a new pressure housing, sphere that guys sit in, is or has been manufactured and the old one will be retired, been in service since 60's, and sent to a museum in DC I think and a new Alvin will be put in service after all the parts are retrofitted to the new one. If anyone is interested I will check out the viewing times and post them here for you. P.
