Remembering Dr. Grant Carleton Edwards



Dr. Grant Carleton Edwards, departed this Earth on Monday 10 September 2018 in Sydney, Australia, due to an unexpected massive heart attack that left the Hg community with a huge void. Grant was a dedicated and respected academic at Macquarie University, previous Associate Professor at University of Guelph, Canada, and research scientist at Agriculture Canada and Ontario Hydro.


Grant’s research passion was measuring fluxes of trace gases including mercury, nitrous oxide, methane, and volatile organic compounds. He was a creative scientist who loved working on developing methods to measure fluxes. Grant enjoyed building and fixing instruments, and was very much a hands-on person. At Macquarie he had developed a trace metal mercury laboratory that was fully operational, and generating very interesting data. Through collaborations with the University of Nevada-Reno, he developed a method to measure reactive gaseous mercury fluxes.  He had many collaborators during his time in Canada, and some that were still ongoing. He developed quite a network of colleagues across Australia for measuring mercury fluxes and air Hg concentrations. This included working with CSIRO Oceans and Atmosphere, to monitor elemental and reactive gaseous mercury at the Cape Grim Baseline Air Pollution Station; and collecting total and reactive gaseous mercury on several voyages from Australia to Antarctica in partnership with the Collaboration for Australian Weather and Climate Research.


Grant was a wonderful student mentor, and his graduate students’ growth and success were of extreme importance to him. He worked hard to teach them and help them develop into outstanding scientists.


Grant had a gentle nature and sociable personality, he was a master chef in the kitchen, and he was passionate about Jaguars. He was much loved and is sorely missed by his family and relatives, and his many students, friends, and colleagues around the world.
