SIMB3 deployment on MOSAiC

See how to assemble, activate, and deploy an SIMB3 in < 30 minutes

About the video

The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) was a yearlong expedition into the Central Arctic that ran from September 2019 – October 2020. During this record-setting expedition, four Cryosphere Innovation Seasonal Ice Mass Balance buoys (SIMB3s) were deployed as part of a distributed network of instruments that surrounded German icebreaker Polarstern.

In this video, University of Utah PhD student Ryleigh Moore walks through how to deploy an SIMB3 at one of the MOSAiC distributed network sites.

What you'll learn

  • How to unbox SIMB3
  • How to activate SIMB3 and confirm transmission to Iridium
  • How to properly assemble SIMB3
  • How to install SIMB3 into the ice hole


We are grateful to Ryleigh Moore of the University of Utah for preparing this video. The SIMB3s deployed during MOSAiC were funded by the National Science Foundation [grant #: 1724424]
