Shelf waves: Simple, fast, accurate MATLAB programs for calculating barotropic shelf waves above arbitrary rectilinear topography bordering an open ocean. The method is described in the note

G. Kaoullas & E.R.Johnson, "Fast accurate computation of shelf waves for arbitrary depth profiles", Continental Shelf Research, 2010 and the MATLAB "SHELFWAVES" program can be downloaded from MATLAB Central as SHELFWAVES.

Coastal-trapped waves: Fast, accurate MATLAB programs for calculating baroclinic coastal-trapped waves in arbitrarily stratified flow above arbitrary rectilinear topography bordering an open ocean. The method is described in the paper

E.R. Johnson & J.T. Rodney, Spectral methods for coastal-trapped waves, Continental Shelf Research, 2011, 31 (14) pp. 1481-1489 doi:10.1016/j.csr.2011.06.009 and the MATLAB "Spectral methods for CTWs" programs can be downloaded from MATLAB Central as Spectral methods for CTWs.

PhD Research

The Geophysical Fluid Dynamics group always has UK Research Council studentships available each year. Early applications (December/January) are advised for EPSRC Departmental Training awards as these tend to be allocated early in the New Year. Students join an active GFD group with interests ranging from eddy dynamics and circulation in the oceans through to vortex breakdown and sudden stratospheric warmings.

UCL offers a wide-ranging programme of training in transferable skills to all graduate students and extra support to encourage students to attend UK and overseas conferences. Information on the level of stipend and details of other benefits can be found on the research council websites:- NERC and EPSRC. Applicants should have, or expect to gain, a good honours degree (first/upper second). Candidates must establish a relevant connection with the UK to meet Research Council eligibility criteria for funding of an award. In order to be considered you need to fill in an application form. Please see UCL Graduate Application, where you can download the forms and guidelines immediately. After you fill in this form, please send the original to the Graduate School and a copy to me. Applicants should also send their CVs, including the names of 2 referees directly to me. UCL Taking Action for Equality.
