TRISTEN experiments have been conducted during 1980, '82 and '84 in each of the three distinctly different Arctic Environments, namely: (a) The pack ice located over the deep water central Arctic Basin, (b) The Marginal Ice Zone (MIZ) located on the periphery of the pack ice in predominantly shallow water. TRISTEN experimental results for propagation loss, ambient noise and medium stability are summarized for each of these three regions individually and where possible amongst the three environments. Of the three environments, acoustic characterization is easiest within the pack ice. Keywords: Underwater acoustics; Underice; and Low frequency.
