The last dive of the cruise. Jim, Helene, and Bruce dove at High Rise at the Main Endeavour Field. They took many fluid samples from high and low temperature venting sites and used both the beast and gas tights.
Fairy Castle (There are no real naming conventions for vents, I hope you’ve enjoyed their names as much as I have).
At Ventnor they measured the high temperature at 332 degrees Celsius and a low temperature between 20 and 21 degrees Celsius. They also made it to Baltic and Boardwalk, where they took similar samples of high and low temperature diffuse fluid samples. Here are some great pictures of black smokers.
After the sub came up from the last dive, the Alvin crew took the “skins” off and we scrubbed them down. The skins are the heavy white plastic pieces protecting the inner workings of the sub. They have to be cleaned after the last dive to get all the salt water off of them since the sub isn’t going to be used for a few months.
Alvin sans skins
Sanjoy, Rika, and John scrub down one of the skins.
The Alvin crew scrubs the rest of the sub and the skins that don’t come off so easily.
Thanks, Sam, for all your posts. You did a great job explaining everything to us laypeople!
