Personal profile

Research expertise

Head of Marine Technology

I joined SAMS in the summer of 2012 as Head of Marine Technology after 27 years working at the British Antarctic Survey (BAS). I started at BAS as a field scientist and instrument designer, spending two austral winterers (1986 and 1991) at the Halley Research Station in the south Weddell Sea, and accumulated a further three years “south of the circle” during summer seasons. I gained my Ph.D. in 1994 on stratified atmospheric boundary layers.

In the 1990s I developed a number of techniques to probe the winter-time polar atmosphere, including low-power autonomous remote systems at the surface and kite, blimp and rocket instrument platforms aloft. In the last 10 years, I have concentrated on the physics of coherent structures in the stable boundary layer, whilst developing the use of small robotic aircraft for measuring the structure of the atmosphere near the surface. At SAMS these techniques will help us understand sea-ice dynamics in the Arctic and help explain the observed dramatic reduction in summer-time sea-ice coverage. My interest in things that fly continues after work, training 'Gaia', a young Harris Hawk, and using kites for skiing.

Research Interests

  • Flux-profile relationships in the Stable Atmospheric Boundary Layer (ABL): During my first Antarctic winter in 1986 I noticed that the turbulent atmosphere during the polar night is more complex than expected, with a variety of coherent structures apparent in a range of fine resolution data, from acoustic radar to sonic anemometers. The mechanism that generates and maintains these structures when the atmosphere is stratified (stable) but turbulent is still obscure; turbulence should act to diffuse or blur any structure, not enhance them. Understanding this effect is of growing importance in improving the accuracy of our climate models, as parameterization schemes that derive surface fluxes from bulk meteorology are very noisy and on average biased. My personal research still dwells in the Stable ABL, working through an international group within GEWEX trying to improve GCMs in this area by understanding the missing physics.

  • Remotely Piloted Aircraft (also known as UAVs): I am leading the SAMS project to developing Earth Observation and in situ platforms for marine research. The project involves training a team of avionics engineers, pilots and commanders for RPA operations, modifying a fleet of Light RPA (< 20kg tow) for over-water deployment, and developing sensor payloads for environmental sampling.
  • Flux buoys: Although many buoy-based systems are operating around the world, the vast majority only  measure meteorology, whilst a fraction measure what is actually needed, fluxes of heat and momentum into the surface. Fluxes are the true coupling conditions that govern air-surface interaction. Making automatic flux measurements is not trivial, but I am adapting relatively standard techniques used on land to work on a mobile platform at sea. Such buoys will help the community validate couple general circulation models in remote oceans, especially polar regions.
  • Glider-Deployed Drifters: I am working in partnership with Southampton University to use the relatively new technique of balloon launched gliders as a vehicle for deploying marine sensors.
