J. Graham CogleyGraham Cogley
1948–2018

It is with great sadness, but also with deep gratitude for his service to our society, that the IGS reports the death of J Graham Cogley, Professor Emeritus in the Department of Geography, Trent University, Canada. Graham died on 4 October 2018 in Peterborough, Ontario. Since May 2016 Graham had been IGS Chief Editor of the Journal of Glaciology and Annals of Glaciology, and related ex-officio functions for the IGS Council and its Publications Committee. Previously, he had served as Scientific Editor for various issues of the Annals, and as Chief Editor of Annals 71 (Glaciology in High Mountain Asia).

Graham’s glaciological research spanned almost five decades and started with field studies, some culminating in his PhD thesis (1975) “Properties of Surface Runoff in the high Arctic”, supervised by Brian McCann, McMaster University. Graham later followed in the footsteps of his colleague and mentor Peter Adams in directing the field measurement programme on White Glacier, a benchmark glacier on Axel Heiberg Island, Canadian High-Arctic. The longevity of White Glacier’s mass balance monitoring programme, initiated in 1959, was only ensured because of the leadership of these two glaciologists, and the leading field worker Miles Ecclestone, all at Trent University. Peter Adams sadly also passed away last week, only a few days before Graham did.

In more recent decades, Graham’s research mainly involved computational data analysis of glaciers, with a focus on mass balance. Graham’s contributions to glaciology include works on glaciers in the Canadian Arctic and High Mountain Asia and extensive and groundbreaking work on global analysis of mass balance data, global glacier inventories and global hydrographic datasets. His contributions to various international reports on glaciers and climate change are invaluable.

Graham will be especially remembered for his scientific enthusiasm, fine writing, sharpness and attention to detail, and for being an extraordinary collaborator. We are also grateful for his mentoring of many young glaciologists, and for his leadership of the IGS editorial team. He will be greatly missed by our entire community.

A full obituary will appear at a later date in ICE.
