Icecube is at the south pole - the zillions of ton s of water is just ice

  Is that true? They don’t fill a chamber with heavy water?

    Water and ice versions exist, IceCube consists of detectors dug into ice and Super Kamiokande (example) is a big container of ultrapure water (not heavy). Hyper Kamiokande will be even bigger. https://en.wikipedia.org/wiki/IceCube_Neutrino_Observatory https://en.wikipedia.org/wiki/IceCube_Neutrino_Observatory https://en.wikipedia.org/wiki/Super-Kamiokande https://en.wikipedia.org/wiki/Super-Kamiokande https://en.wikipedia.org/wiki/Hyper-Kamiokande https://en.wikipedia.org/wiki/Hyper-Kamiokande

      Most neutrino experiments don't/didn't use heavy water, but the SNO experiment did. https://en.wikipedia.org/wiki/Sudbury_Neutrino_Observatory https://en.wikipedia.org/wiki/Sudbury_Neutrino_Observatory

    Not at the pole - the ice is essentially transparent, they made a 3d grid of detectors by melting deep holes in a grid and dropped strings of detectors that then froze in place
