VLA A-array 21cm atomic hydrogen (HI) absorption observed against the central region of the starburst galaxy M82 and MERLIN HI absorption measurements which show HI absorption against 26 of the supernova remnants are discussed. These observations have been compared with the molecular (CO) and ionised ([NeII]) gas distributions and used to constrain the dynamics and structure of the ionised, neutral and molecular gas in this starburst.
