The IceCube Neutrino Observatory is a cubic-kilometre array of sensors embedded 1.5–2.5 km below the South Pole’s ice, making it both the world’s largest neutrino detector and literally "buried deep in the ice." It is also employed to search for signals from dark-matter annihilation, so all three statements are correct.
