Since the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition began in September 2019, the Atmospheric Radiation Measurement (ARM) user facility has had technicians on the icebreaker R/V Polarstern to oversee its 50-plus instruments.
The Alfred Wegener Institute (AWI), which leads MOSAiC, is producing daily blog updates on the expedition. On May 3, 2020, the AWI blog featured two ARM technicians currently on Leg 3 of MOSAiC: John Bilberry of Los Alamos National Laboratory and Dean Greenamyer of Hamelmann Communications. Bilberry and Greenamyer will complete Leg 3 in a few weeks before the next set of ARM technicians boards the Polarstern.
Below is a screenshot of the AWI blog post featuring Bilberry (left) and Greenamyer.
