Dear all,
We are pleased to invite you to the next WISE Webinar on the topic of Wave in sea ice on 28/08/2025 at **9:00AM CET (**5 PM Melbourne time).
Join us via https://tudelft.zoom.us/my/wisezoominars on 28th August at 9:00 -10.00AM CET time!
First speaker: Jean Rabault, Norwegian Meteorological Institute
Title: Waves in ice: large datasets from low-cost buoys and their use
Abstract:
This presentation will provide an overview of the general design and capabilities of the OpenMetBuoy, a low-cost, open-source buoy system designed for studying sea ice and ocean interactions. We will present data collected from recent deployment campaigns, highlighting the insights gained through the use of buoy clusters in the marginal ice zone. Additionally, we will demonstrate how these datasets have contributed to model improvements with operational implications, as well as new scientific understanding of processes such as sea ice drift and wave-ice interactions. These results underscore the potential of OpenMetBuoy and similar open source low cost platforms to advance both research and practical applications in polar and oceanographic sciences.
Second speaker: Luke Bennetts, The University of Melbourne
Title: On defining the marginal ice zone
Abstract:
The marginal ice zone is the region of the sea ice covered ocean in which the ice cover is regularly affected by ocean waves. For many years, a sea ice concentration band has been used as a definition of convenience for the marginal ice zone, although it has no obvious connection with waves. I will assess the width of the Antarctic marginal ice zone over multiple years using new radar altimetry analysis and a numerical sea ice model that includes wave–ice interactions. I will explore definitions based on wave heights and on ice floe sizes, and contrast these with the concentration-band definition.
Please note that WISE Webinars including the Q&A will be recorded and posted on the WISE YouTube Channel afterwards (https://www.youtube.com/@wisezoominars). By participating, you consent to any information you share to be included in the recording and shared.
Best wishes,
Alvise, Bernard, Tripp, Morteza, Alberto and Qingxiang.
