ABSTRACT: Ross Mackay™s main scientific accomplishments were as a permafrost scientist working in the Western Canadian Arctic. Starting in 1951, he would spend approximately 3 months in the field each year for more than 40 years. He described many geographical features including the closed-system pingos of the Mackenzie Delta. In 1968, when the PCSP Western Arctic logistics base moved to Tuktoyaktuk, he commenced long-term permafrost studies in the delta region. His research added significantly to our general understanding of permafrost terrain, the nature of ground ice, the controls over permafrost distribution, the dynamics of the active layer and the effects of natural and man-induced disturbances to the tundra and arctic ecosystems.

RÉSUMÉ: Les principaux accomplissements scientifiques de Ross Mackay ont été en tant que chercheur du pergélisol travaillant dans l™Arctique de l™Ouest Canadian. Dès 1951, il passa environ 3 mois par an sur le terrain durant plus de 40 ans. Il décrivit de nombreuses formes géomorphologiques dont les pingos de système fermé du Delta du Mackenzie. En 1968, lorsque la base logistique d™Arctique de l™Ouest du PPCP fut déménagée à Tuktoyaktuk, il commença des études à long terme sur le pergélisol dans la région du delta. Ses travaux ont contribué de façon majeure à notre compréhension générale des terrains de pergélisol, de la nature de la glace de sol, des facteurs contrôlant la distribution du pergélisol, de la dynamique de la couche active et des effets des perturbations naturelles et anthropiques sur la toundra et les écosystèmes arctiques.
