RESEARCH INTERESTS My research focuses on the interaction of glacial and sea-ice meltwater with the upper ocean. I am interested in how the addition of freshwater at the surface (from sea ice) or at depth (from glacial meltwater) can result in mixing or stabilisation of the upper ocean, and how the presence of these freshwater sources affects the distribution of the other. To investigate this, I combine observational data with one-dimensional ocean modelling, using a model I have developed to include sea ice. In addition to ship-borne measurements, I deploy ocean gliders and am passionate about the development of this technology to return under-ice measurements.

FIELDWORK EXPERIENCE

I have over 20 weeks of shipboard experience, 19 weeks of which are in the Southern Ocean. Skills include deployment and recovery of ocean gliders, CTD deployments, water sampling and processing, oxygen Winkler titrations and shipboard ADCP operations.

I am learning Swedish, and a recent evaluation placed me at the CEFR level B1/2 (Feb 2019).
