Background:

Sam Hartharn-Evans is a researcher at Northumbria University investigating how the ocean and ice shelves in Antarctica interact, specifically, how the meltwater plume beneath ice shelves mixes with the ocean using laboratory scale process models to understand these systems.

In his spare time Sam is a trombone player, and Secretary of the UniBrass Foundation – the charity behind the University brass band championships, which Sam ran in 2019. Sam has been on the UKPN committee since 2021, initially as treasurer, and has is now pleased to be the Antarctic co-president.

Research:

Sam’s PhD research is primarily laboratory based, his PhD used laboratory scale (7m x 0.3m) experiments to understand the processes and dynamics that link sea ice and internal solitary waves, particularly focussed on understanding how the two systems interplay at this interface. He particularly enjoys that in the lab we are able to directly see these waves that can be elusive and tricky to understand in the field. This research is also complimented by numerical models, which became particularly useful during lockdown!
