Andrew Gray

About me

I study the ecology and biogeochemistry of Polar environments using field-based methods, drones and satellites. My interest in this area started during my Masters and PhD (both at the University of Sheffield) where I investigated glacial biogeochemistry in Svalbard and Greenland. I then discovered remote sensing and went on to map snow algal biomass across the Antarctic Peninsula on a project based out of the University of Cambridge. I am currently a Research Co-I on a NERC Standard Grant at the University of Edinburgh scaling our snow algae observations across the Antarctic coastline and exploring the controls on bloom distribution.

Alongside research, I manage operations at the NCEO Field Spectroscopy Facility based at the University of Edinburgh, where we provide free-at-the-point-of-delivery equipment and training to UK-based researchers. This means I keep up to date with state of the art earth observation equipment and methodologies, and have exposure to a variety of different remote sensing projects, from agricultural applications to geological mapping.
