I am a physical oceanographer focused on ocean circulation and water-mass transport. My research so far has centred on the Southern Ocean, combining ship-based observations, satellite data and ocean reanalyses to investigate the structure and variability of its currents and water masses. I am particularly interested in understanding how physical processes shape ocean connectivity and influence marine ecosystems in a changing climate.

A guide to open hydrographic data in the Southern Ocean: seals, floats and ships

How do you study an ocean that is difficult to reach, frequently covered by sea ice, and far from most research institutions? Collecting observations is one challenge. Finding the measurements that already exist can be another. Temperature and salinity profiles reveal how seawater properties change with depth, helping oceanographers identify water masses and investigate the …[Read More]
