Abstract:
We present preliminary results from this year's deployment of 30 wavebuoys into the Beaufort Sea drifting ice cover. The buoys were deployed in two phases, both as part of the Office of Naval Research Marginal Ice Zone Departmental Research Initiative. 20 buoys were deployed into the continuous pack ice using aircraft-staged camps from Banks Island in March/April 2014, and the remaining 10 buoys were deployed from the South Korean icebreaker Araon in August 2014. All buoys transmitted continous timeseries of heave, roll and tilt - sampled at 1Hz - over the Iridium satellite network, along with their GPS positions. The goal is to examine the attenuation of storm-driven ocean waves as they enter and fracture the Beaufort Sea ice cover. These data are presented and the evolution of the directional wave field as it travels through the ice cover is examined.
