Dr Graham Quartly is a Senior Scientist at PML working on the development of remote sensing techniques and their exploitation to tackle questions in physical and biological oceanography. Graham has a PhD in Underwater Acoustics from the University of Bath, and more than 20 years experience in satellite-based remote sensing from work at the UK's National Oceanography Centre (NOC) and its forerunners. His chief area of expertise has been altimetry (in which he has been an accredited PI on almost all projects). He has also written papers on ocean colour and sea surface temperature data.

Graham's work ranges from detailed technical work related to calibration of sensors and their long-term monitoring to applications of remote-sensing data to address scientific issues in physics, climate and biological science. He has worked on a number of European Space Agency projects on currents, waves and sea level, and has acted as a reviewer for a large number of journals and external funding bodies. He has published over 80 papers.
