Moire Anne Wadleigh Student Prize in Stable Isotope Science

The Moire Anne Wadleigh Student Prize in Stable Isotope Science is awarded to the student presenting the best paper or poster at the Advances in Stable Isotope Techniques and Applications (ASITA) Conference, as determined by an independent panel of judges convened by the conference organizers. 
 

This prize is given in memory of Professor Moire Anne Wadleigh, a prominent member of the Canadian stable isotope community, and co-organizer of the 2002 Canadian CF-IRMS Workshop at Memorial University. Dr. Wadleigh contributed an enormous amount to our science in her all too short life. Her MSc thesis research on strontium isotopes in rivers, conducted at the University of Ottawa, remains the first and critical reference on this topic. Her PhD research at McMaster on the isotopic behaviour of sulphate in rain, and the environment more generally, was years ahead of its time in helping us to track and understand the movement of these compounds in the atmosphere. Dr. Wadleigh’s post-doctoral research on the oxygen-isotope composition of ancient oceans, and its implications for Earth’s evolution, remains central to one of geochemistry’s most important controversies. Her work as a Research Associate at The University of Western Ontario on fluid-flow in the continental crust provided new ways of understanding these systems. But her most enduring scientific contributions are, and will be, her pioneering research conducted at Memorial University from 1991 to 2004, in collaboration with her staff and students.
 

Professor Wadleigh had a fascination with the behaviour of sulphate and nitrate in the atmosphere. She studied these compounds in rain, in aerosols, on lichens – wherever they might be had – to understand their origin and their impact on Earth. At the time of her death, she was actively engaged in the Canadian and International SOLAS projects to determine the connection between ocean uptake of greenhouse gases and natural emissions of sulphur-bearing compounds. During all of these investigations, Dr. Wadleigh worked very closely with her graduate students. She gave them her time and advice without limit, and she gave them room to evolve their own ideas as young scholars.
 

It is therefore fitting that we honour her memory in this way.
 

The Moire Anne Wadleigh Student Prize was established and endowed by FJ Longstaffe in 2005. Additional donations from the 14^th Canadian CF-IRMS Workshop, jointly hosted by the University of Saskatchewan and Environment Canada in Saskatoon in 2008, the 15^th Canadian CF-IRMS Workshop, at Cornell University in 2009, ASITA 2016, in Philadelphia in 2016, ASITA 2017 in Waterloo in 2017, and ASITA 2019 (G Koehler) in Winnipeg in 2019 have further strengthened the Prize. This year, the prize is worth 600$CAD.
