12 September – there has been good progress in the operation so far!
The two cable reels are also deployed. The cables for connecting four detection units are already layed on the sea bottom and connected to the junction box. There is only one cable left to install.
While proceeding with these activities, however, the weather conditions worsened. The sky was still sunny, but waves mounted high: “We have a lot of sun here, but we are dancing a lot” commented Daniele Vivolo, who is among the KM3NeT team onboard the ship.
In such situation the risks when putting the equipment in water increase significantly. It was therefore decided to put the operation on hold, waiting for an improvement of the sea state.
In late afternoon, the sea had calmed down significantly, and the operations were resumed.
As we write this post, the first detection unit of the set of five included in this campaign is already in water, travelling into the deep, dark sea, down to 3,500 meters depth. There it will meet the ROV (the submarine vehicle operated from the ship), which will take care of the next steps: to assist in carefully positioning the detection unit on the sea bottom and to connect it to the cable already in place. Have a safe trip!
In the movie: the first detection unit is prepared for deployment.
