This paper presents a synopsis of 2 decades of research contribution to Arctic hydrology carried out at the McMaster basin. Discussions will focus on 2 topics of special significance to the Arcticregion, being snow and permafrost hydrology.

The location of the Arctic front for the winter months are investigated. The Arctic front is identified on every daily synoptic weather chart, and five year mean (1958-62) monthly frequency distribution is examined. Principal Arctic frontal zones
are recognised in the Northern Atlantic-Eurasian region and in the Northwestern part of North America. (L'A.).
Pedogenic zonation in the well drained soils of the Arcticregions
The processes of podzolization, decarbonization-carbonization, pervection, and salinization as models of arctic pedogenesis demonstrate that processes occurring in the temperate region also operate in Far North.
Warming of permafrost in the Arctic National Wildlife Refuge, Alaska
-long warming documented for the central and western Arctic has also occurred in the region near Barter Island and in the northern Arctic NWR.
This paper reports borehole temperature measurements made in permafrost over a period of 2 decades (1985, 1988, and 2004) at sites on Barter Island and in the Arctic National Wildlife Refuge (Arctic NWR). These measurements indicate that the century
Trends in year-to-year fluctuations in surface air temperature, Canadian Arctic
Long term trends in the year-to-year fluctuations in the mean annual temperature anomalies from 1948 to 1983 were obtained for eight regions in the Arctic. The results indicate that the temperatures in the Canadian Arctic as a whole, have become
more variable. The magnitude of the year-to-year fluctuation has increased quite markedly in four of the eight regions since the early 1970 s.
