ARM technician Juarez Viegas works on a power distribution and data logging system installed out on the sea ice.The Ka- and X-band scanning ARM cloud radars are on the icebreaker R/V Polarstern. While the Ka-band radar is running well during MOSAiC, the X-band radar has experienced some technical difficulties. In the sky beyond the radars is the green laser beam of a partner lidar.Without the sun, spotlights from the Polarstern help researchers and technicians work on the ice.A new pressure ridge of ice forms near ARM’s “swing set” of ground thermometers and radiometers at Met City, the research station where ARM meteorological instruments are operating on the ice.MOSAiC team members must be resourceful in the remote central Arctic. Here they put down a sled to use as a footbridge for crossing over a crack in the ice.
Coming up next: Shupe gives us more images from the ice.
MOSAiC is an international arctic research expedition led by the Alfred Wegener Institute with U.S. contributions from the U.S. Department of Energy, National Science Foundation, National Oceanic and Atmospheric Administration, and NASA.
