ARM has three technicians—Paul Ortega and John Bilberry, both from Los Alamos National Laboratory, and Dean Greenamyer, Hamelmann Communications—on Leg 3 of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. In early March 2020, the group came aboard the icebreaker R/V Polarstern.
