A compilation and discussion of all available information on the Soviet development of drifting automatic weather stations and radio beacons and their deployment in the Arctic Basin. Although no detailed instrumentation data have appeared in the open literature, general information on the design and history of the Alekseyev beacons and DARMS has appeared in Russian scientific publications. The DARMS weighs only 450 lbs and covers 40 sq ft. It is tuned to a fixed frequency and can be activated and interrogated by ship, shore, or aircraft. Its 40-w transmitter has a wavelength of 430 to 630 m and a range of 800 to 1500 km. The automatic stations can be deployed on the drifting ice by aircraft or icebreaker; installation requires less than an hour. From 1953 through 1965, 133 beacons and 141 DARMS were deployed. Additional data and background material are given in the appendixes. 77 pp. Bibliog.
