I am currently working on interpreting results from a field project (ASTTEX) which took place in 2003 - 2005 in the Cape Basin of the South Atlantic Ocean. The goal of ASTTEX was to resolve interocean fluxes (Indian to Atlantic) at a high resolution both spatially and temporally, and to be able to distinguish the independently varying components of the interocean salt and heat fluxes. ASTTEX stands for "Agulhas-South Atlantic Thermohaline Transport Experiment". The 16 moorings deployed by ASTTEX formed the largest array deployed to date in the South Atlantic Ocean; the array stretched approximately 1000 km across the Cape Basin. This work is supported by the NSF and NASA.

I am also working extensively with altimeter data around Africa, with an eye to measuring the interocean fluxes remotely. This work is supported by the NASA New Investigator Program (NIP).

Last but not least, I am working with high-resolution (POP) model output in the Agulhas region, using the model as a testbed to investigate how high-frequency motion may be aliased into time series of transports made from altimetry. This work is supported by the NASA Ocean Surface Topography program.

Related interests are to find ways to accurately predict vertical structure in the ocean (i.e., salinity, temperature, density, baroclinic velocity) from integrated measures. In particular I have been very involved in the development of new techniques which integrate of satellite altimetry with moored inverted echo sounder (PIES) data promising new technology for monitoring oceanic fluxes in areas of complex stratification.

I believe that the creative exploration and visualization of data is an important source for the discovery of new scientific knowledge and techniques. I use Matlab (tm) almost exclusively for that purpose and have written several Matlab packages to assist in the process: a GUI for the The OPeNDAP project as well as a standalone package called STAPLOT for hydrographic analysis. STAPLOT is not currently being maintained. I do everything on the linux operating system if I possibly can.

Teaching Interests: a synthetic approach to descriptive physical oceanography at various scales, creative data exploration and vizualization on the computer, remote sensing techniques and applications.
