Overview

Tom is the established Chair in Physical Oceanography. He is an observational oceanographer with a strong research interest in turbulence and mixing in the marine environment. His work has involved the development of new technqiues for the measurement of aquatic turbulence, and the use of turbulence measurements to identify, unravel and quantify key physical processes which drive mixing in the ocean. His current research focuses on the impact of mixing by the tide and wind on melting Arctic sea ice and the processes determining the surface mixed layer depth in the ocean.

Tom is a Fellow of the Royal Meteorological Society and a Senior Fellow of the Higher Education Academy.

• PhD: Physical Oceanography
  University Of Wales, 1993
• MSc: Physical Oceanography
  University Of Wales, 1989
• BSc: Physics and Meteorology
  University of Reading, 1987

I teach physical oceanography and meterology across a range of modules at undergraduate and MSc level. I have also supervised numerious MSc porjects.

PhD supervision includes:

On-going: Brian Scannell, Katie Sieradzen (lead) and Natasha Lucas (co)

Completed (Lead): Jingnan Li (2017), John Siddorn (2015), Ben Lincoln (2012), Eleanor Howlett (2010).

Completed (co): Jess Mead Silvester (2017), Charlotte Williams (2014), Holly Pelling (2013), Phil Wiles (2008), Matthew Palmer (2008), Neil Fisher (2004).

Tom offers a number of very timely research topics for PhD and MRes study here at Bangor University. These cover Arctic Ocean mixing processes, the role of vertical mixing in biogeochemical cycling of nutrients and carbon in the ocean and in lakes, and the development of techniques to measure turbulence in the aquatic environment.
