Nansen Legacy sea ice workshop. A two day workshop delivered on 20-21 October. It was aimed a bringing researchers in multiple disciplines together to discuss / discover data availability, data needs, collaboration opportunities. Co-organised with Stefan Theile (University in Bergen) and Elizabeth Jones (Institute of Marine Research).

I assisted with schedule development and setting the workshop style; and identified / coordinated the code of conduct. In the workshop I convened the first session, coaching on how and why we use a code of conduct; then running an interactive execrise to collaboratively set guidelines on how we implement the code of conduct during the workshop. I also convened sea ice physical properties sessions.

Filling in gaps: fusing high resolution imagery products from remotely piloted aircraft (RPA) and on-ground measurements to understand the spatial distribution of sea ice morphological features at sub-floe scale.

Sea ice and snow field techniques. Workshop: in-field bespoke training on sea ice and snow research techniques. Delivered in February 2022 on landfast sea ice in Ramfjorden, near Tromso.

My role in workshop preparation was curriculum codesign, safety and logistics management.

I delivered safety briefings on site, then taught students on how to design walked survey transects for sea ice; use of electromagnetic induction instruments (geophex GEM-2); use of snow probes (SnowHydro Magnaprobe)

Towards high resolution estimates of East Antarctic pack ice thickness. My doctoral thesis. It introduces sea ice physical and ecological systems, explains why mapping sea ice topography in high resolution is critical to understanding this frozen ocean, and does a lot of engineering work about actually making maps of sea ice with airborne laser scanners, photogrammetry, and ground survey data. It concludes by showing how this intensive approach adds to our understanding, and openly detailing where improvements can be made. See:
