MOSAiC Blog: Sights of the Arctic, Part 4

Published: 18 May 2020

Editor’s note: ARM technician Tercio Silva of Hamelmann Communications worked on Leg 2 of the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Here are some photos Silva sent back from his time on the expedition. Photos are by Silva except where indicated.

Tercio Silva fixes ARM network cable during MOSAiC — In the wind, I am fixing ARM network cable going to the ice communications and power distribution unit at Met City in February. This is where ARM meteorological instruments are installed on the ice. Photo is by Éric Brossier, Polar Yacht Vagabond.

Tercio Silva on a walk during MOSAiC — Here I am on a walk with the R/V Polarstern in the background. Photo is by Johannes Pliet, FIELAX GmbH.

The Polarstern during MOSAiC — The Polarstern provides a backlight for Met City.

ARM laser disdrometer during MOSAiC — ARM has a marine atmospheric emitted radiance interferometer (right) on the Polarstern to collect spectral infrared measurements. In the distance is the icebreaker Kapitan Dranitsyn, which was heading to the Polarstern for the Leg 2 to Leg 3 resupply.

Ka-Band ARM Zenith Radar and radar wind profiler during MOSAiC — An icy glaze covers ARM instruments on the Polarstern, including the Ka-Band ARM Zenith Radar (KAZR) and radar wind profiler.

Tethered balloon being prepared to launch during MOSAiC — This is a view of the AWI (Alfred Wegener Institute) Balloon Town from the Polarstern. A tethered balloon is being prepared for a launch.
