If I were writing a story about this, I would have the IceCube / IceTop / DeepCore neutrino observatory be a cover-up for drilling deep sampling tunnels into the submerged alien ship, through which robotic probes would be deployed into the wreck. https://icecube.wisc.edu/science/icecube/ Perhaps in the story, there's a still-active hostile AI inside the ship and robots that are brought back up have been reprogrammed to hurt the human staff and then sneak aboard the medivac aircraft to reach the mainland and physically infiltrate key data centers, or something like that.

I am sure you are familiar with the details since you are spot on. Look into it a little bit, definitely a lot of strange things going on surrounding IceCube.
